Description

Optical Transceivers and Optical Switches

The present disclosure generally relates to optical transceivers, and more particularly, to a dual socket transceiver that allows sequential connection of optical and electrical sockets.

With the advent of cloud computing applications, decentralized network systems have been widely adopted. Network systems contain many connected devices, including servers, switches, and other components that exchange data. In the past, the connections between such devices were largely wired, but with the increased demand for speed and data volumes, faster optical signal cables have been used. For example, the transmission speed in recent optical systems exceeds 10Gbps and reaches 100Gbps, thus meeting the need for increasing data capacity and speed.

Optical signals are sent and received through transceivers, which have electronic components that are the necessary electronic components to relay optical signals and convert such signals into standard electrical signals. An optical transceiver transmits and receives optical signals through an optical connector, the optical connector is matched with an optical actuating device, and the optical actuating device includes a light-emitting device and a light-receiving device, each made of semiconductor material . An optical transceiver includes electronic components and an optical connector. A plug-in optical transceiver is one type of optical transceiver. The optical transceiver is inserted into or removed from a transceiver cage, which is provided on a printed circuit board in an optical switching device. The optical connector of the transceiver is fitted with an optical socket in the optical switching device.

Optical transceivers convert optical signals to electrical signals and are often used to integrate optical switches into components that are connected via traditional copper wire-based networks. At present, the optical network switch will have a series of optical signal sockets, such as multi-fiber pull off (MPO) sockets, which can transmit and receive optical data to and from the optical network. Such switches will also feature a range of sockets for transmitting and receiving lower bandwidth electrical signals, such as Quad Small Form-factor Pluggable (QSFP) sockets. Data communication between the optical receptacle and the electrical receptacle requires an electrical-to-optical transceiver interface that connects the optical receptacle to the electrical receptacle in the optical switch. Since such transceivers are prone to damage, they need to be able to be plugged into and unplugged from the appropriate sockets so that they can be replaced if damaged. Currently, separate optical transceivers must be used in conjunction with separate connector cables to connect to the corresponding electrical sockets.

The order of connection is also important, since the optical connection to the optical transceiver should be made before the connection to the electrical outlet. Providing a separate cable for connecting a known optical transceiver may therefore result in the wrong order of connecting the cable to the electrical socket before inserting the transceiver into the optical socket.

Therefore, there is a need for an optical transceiver that allows connection between optical and electrical signal receptacles. There is also a need for an optical transceiver that can be locked and unlocked to allow sequential connection of the two types of connectors. There is also a need for an optical transceiver that can be easily deployed to connect optical and electrical receptacles.

The present disclosure is directed to an optical transceiver assembly having an optical connector and an electrical connector. The optical transceiver allows simultaneous connection of an optical connector to an optical signal socket and an electrical connector to an electrical signal socket. Optical transceivers allow optical connectors to be connected before electrical signal connectors to ensure proper connection sequence. The optical transceiver includes a handle that allows a user to engage and disengage the optical and electrical connectors from corresponding sockets on an optical signaling device (eg, an optical switch). The optical and electrical connectors are movable relative to a housing of the optical transceiver assembly. Pulling the handle disengages the connector from the receptacle and then allows the optical transceiver assembly housing to be pulled away.

FIG. 1A is a cutaway perspective view of an example optical communication device, which in this example is an optical switch 100 . Optical switch 100 includes a housing 110 that holds supporting components such as power supplies, fans, storage devices, and controllers. Optical switch 100 routes optical signals transmitted and received from optical fibers to external networking devices, such as servers. Optical switch 100 is based on a co-packaged optical assembly that manages the transmission and reception of optical signals from optical fibers. A controller, such as a processor, acts to switch the signal between the optical fiber and the conventional electrical port. The optical switch 100 allows high-speed exchange of signals between different nodes in a network environment, such as a data center.

The optical assembly includes a high density organic substrate circuit board 112 , a switching logic controller 114 and an optical module 116 . In this example, there are sixteen optical modules 116 arranged on the circuit board 112 in groups of four. In this example, the light modules 116 are arranged around the switching logic controller 114 . The switching logic controller 114 in this example is a specific application An application specific integrated circuit (ASIC), including switching logic, is used to transmit signals between the optical modules 116 through connection pins. Each optical module 116 has three fiber array ports on the outside facing the switching logic controller 114 . One of the optical fiber array ports transmits the optical signal, and the second optical fiber array port receives the optical signal. The third fiber array port is optically connected to the external light source module to receive the continuous wave laser signal to drive the light module 116 . Each optical module 116 is optically coupled to a series of fiber array ports or optical receptacles 120 . In this example, the optical receptacles are multi-fiber receptacles, but other types of optical receptacles can also be used. Optical switch 100 has a controller, such as a central processing unit, also coupled to standard electrical interface circuitry, which is connected to electrical signal port 122 . In this example, the electrical signal ports 122 are quad small form factor pluggable receptacles, each receptacle including receptacles 124 that allow insertion of a four channel small form factor pluggable connector. Other types of electrical signal connectors can be used.

FIG. 1B is a perspective view of the housing 110 of the optical switch 100 shown in FIG. 1A , showing a rear panel 130 holding the optical socket 120 . The series of electrical sockets 122 are located between the optical sockets 120 on the top row of the rear panel 130 . Electrical signals from electrical receptacle 122 may be converted to optical signals for optical receptacle 120 . Another series of optical network sockets 132 are arranged below the row of optical sockets 120 and electrical sockets 122 . The optical network socket 132 allows communication with network nodes, such as servers, which are connected to the optical switch 100 by fiber optic cables.

In this example, a high-speed optical signal from one of the optical receptacles 120 may be converted to a low-speed electrical signal for reception by one of the electrical receptacles 122 . Similarly, low-speed electrical signals transmitted by one of the electrical sockets 122 may be converted to high-speed optical signals for reception by one of the optical sockets 120 . To connect one of the optical receptacles 120 to an adjacent electrical receptacle 122, an example optical transceiver assembly 150 may be inserted to connect one of the optical receptacles 120 to an adjacent electrical receptacle One of 122. FIGS. 1A-1B show an example optical transceiver assembly 150 of one of the optical switches 100 attached to the rear panel 130 , and the optical transceiver assembly 150 detached from the optical switch 100 .

Figure 2A is a perspective view of the example dual optical transceiver assembly 150 of Figures 1A-1B. FIG. 2B is a perspective exploded view of the components of the example optical transceiver assembly 150 . FIG. 3A is a top perspective view of the housing 210 and the handle 212 . FIG. 3B is a front view of an example optical transceiver assembly 150 . FIG. 3C is a bottom view of an example optical transceiver assembly 150 . Figure 3D is a side view of an example optical transceiver assembly 150. FIG. 3E is a top view of an example optical transceiver assembly 150 . Referring to FIGS. 2A to 2B and 3A to 3E, the optical transceiver assembly 150 is a two-in-one connector carrier for the connection of an optical socket and an electrical socket. The example optical transceiver assembly 150 includes a housing 210, a handle 212, an electronics enclosure 214, a four-channel small package pluggable latch mechanism 216, a four-way small package pluggable connector 218, a multi-core Fiber latch mechanism 220 and a multi-core fiber connector 222. The example optical transceiver assembly 150 has a two-in-one connector configuration including a four-channel small form factor pluggable connector 218 for electrical signals and a multi-fiber fiber connector 222 for optical signals. The electronics enclosure 214 contains circuitry that converts electrical signals from the quad small form factor pluggable connector 218 to optical signals for the multi-core fiber optic connector 222 . The electronics enclosure 214 has a bottom panel and walls closed by a cover plate 224 . The bottom panel of the electronics enclosure 214 has various slots that allow the housing's registration features to attach to the four-channel small package pluggable latch mechanism 216 and the multi-fiber latch mechanism 220 . The cover plate 224 may be attached to the electronic equipment housing 214 by fastening means, such as screws. The housing 210 is attached to the four-channel small package pluggable latch mechanism 216 and the multi-fiber latch mechanism 220 and moves relative to the electronics enclosure 214 . The handle 212 is connected via the housing 210 to the four channel small package pluggable latching mechanism 216 and the multi-fiber latching machine Structure 220 to assist in insertion of optical transceiver assembly 150. When the optical transceiver assembly 150 is attached to the optical switch 100, the configuration of the optical transceiver assembly 150 allows the four-channel small package pluggable receptacle 122 and the multi-fiber fiber receptacle 120 to be connected in sequence, as shown in FIG. 1A.

Housing 210 of optical transceiver assembly 150 includes sidewall 230 and sidewall 232 joined by bottom plate 234 . The housing 210 is attached to the electronic device housing 214 to cover the electronic device housing 214 . The rear plate 236 is attached to the side of the electronics housing 214 to provide a stop for one end of the two springs 238 . The springs 238 are mounted in conduits formed on the bottom panel of the electronics enclosure 214 . The four-channel small package pluggable latch mechanism 216 and the multi-fiber latch mechanism 220 are fixedly attached to the handle 212 via the housing 210 . Accordingly, the four-channel small package pluggable latch mechanism 216 and the multi-fiber latch mechanism 220 , the housing 210 and the handle 212 all move relative to the electronics enclosure 214 . Opposite ends of the springs 238 contact protrusions extending from the bottom plate 234 of the housing 210 .

The handle 212 includes a curved grip portion 240 having two opposite ends 242 and 244 . The opposite end 242 and the opposite end 244 each include an outer slot 246 . Grip portion 240 includes a crossbar member 248 connecting end 242 and end 244 . A connecting member 250 extends from the crossbar member 248 to connect the handle 212 with mating registration features in the housing 210 . The connecting member 250 moves through the aperture in the rear plate 236 . Sidewall 230 and sidewall 232 each have individually extending end tabs 252 and end tabs 254 that are inserted into slots 246 in ends 242 and 244 of handle 212 . The slots 246 of the handle 212 may be secured to the end tabs 252 and 254 via rivets, screws or other connectors.

Sidewall 230 of housing 210 includes internal registration features that contact electronics housing 214 to guide movement of housing 210 relative to the electronics housing. Sidewall 230 includes guide tabs 256 at the opposite end of end tabs 252 to assist in positioning housing 210 Positioned relative to the electronics housing 214 is maintained. Sidewall 232 of housing 210 includes internal registration features that guide movement of housing 210 relative to the electronics enclosure. A guide protrusion 260 extends from the end of the side wall 232 opposite to the end protrusion 254 . The opposing guide tabs 262 extend parallel to the guide tabs 260 . The bottom plate 234 includes a cutout parallel to the side wall 232 , and the cutout includes a support arm 264 extending downward to support the guide protrusion 262 . Guide tabs 260 and 262 include internal registration features that guide movement of housing 210 relative to electronics chassis 214 that retains the portion of four-channel small package pluggable latch mechanism 216 .

The multi-fiber latch mechanism 220 is attached to the housing 210 and can be moved relative to the electronics enclosure 214 by moving the handle 212 . The bottom plate 234 of the housing 210 has two upwardly extending projections 270 and 272 . The tabs 270 and 272 extend through slots in the bottom panel of the electronics housing 214 and mate with registration features of the multi-fiber latch mechanism 220 . The four-way small package pluggable latch mechanism 216 is attached to a registration feature of the housing 210 that is located inside the guide tabs 260 and 262 facing the four-way small form factor pluggable latch mechanism 216 . The four-channel small package pluggable latch mechanism 216 is thus movable relative to the electronic device chassis 214 by moving the handle 212 . As shown in FIG. 3A , the bottom plate 234 includes two retaining tabs 310 extending through corresponding slots in the bottom panel of the electronic device housing 214 . The stop tab 310 retains one end of the spring 238 . Moving the housing 210 thus causes the springs 238 to compress between the stop tabs 310 and the rear plate 236 of the electronics housing 214 .

As will be explained, the four-channel small package pluggable latch mechanism 216 and the multi-fiber latch mechanism 220 are movable relative to the electronics housing 214 between an extended position and a retracted position. Figure 3F shows the housing 210 between the extended and retracted positions of the four channel small package pluggable latch mechanism 216 and the multifiber latch mechanism 220 positioning between.

The spring tension of the spring 238 in the unconstrained state generally maintains the four-channel small package pluggable latch mechanism 216 and the multifiber latch mechanism 220 in the extended position, as shown above in Figure 3F. Pulling the handle 212 moves the four channel small package pluggable latch mechanism 216 and the multifiber latch mechanism 220 to the retracted position while compressing the spring 238 against the stop tab 310 . The stop tabs 310 contact the stop features of the bottom panel of the electronics housing 214 in the fully retracted position, as shown below in Figure 3F.

FIGS. 4A-4F are bottom and bottom perspective views showing the sequence in which the optical transceiver assembly 150 is removed from the optical switch 100 in FIG. 1 . Similar elements are marked with the same symbols in Figures 4A to 4F as their counterparts in Figures 1 to 3. FIGS. 4A-4B show the optical transceiver assembly 150 fully inserted into the housing 110 of the optical switch 100 . The optical switch 100 includes a circuit board 400 holding one of the multi-core fiber receptacles 120 and one of the four-channel small package pluggable receptacles 122 . The multi-core fiber receptacle 120 has a body 410 with optical interface electronics. The body 410 includes a mating connector 412 and two pins 414 and 416 that engage the multi-fiber latch mechanism 220 to maintain the multi-fiber in the multi-fiber connector 222 and the mating connector 412 of the multi-fiber receptacle 120 of optical communication.

The quad small package pluggable receptacle 122 includes a receptacle 124 having walls that guide the quad small package pluggable latch mechanism 216 . The receptacle 124 has an open end 432 to allow insertion of the four-way small package pluggable latch mechanism 216 . The opposite latched end of the jack 124 has a four-way small package pluggable socket 434 that mates with the four-way small form factor pluggable connector 218 to allow electrical signal communication. Receptacle 124 has two prongs 440 and 442 near open end 432 that mate with four channel small package pluggable latch mechanism 216 .

When the optical transceiver assembly 150 is inserted into the enclosure 110 , the handle 212 is pushed in relative to the electronics enclosure 214 . Therefore, the spring 238 between the rear plate 236 of the electronic device housing 214 and the retaining protrusion 310 is in an unconstrained state. In the inserted position, the four-channel small package pluggable latch mechanism 216 and the multi-fiber latch mechanism 220 are in an extended position relative to the electronics enclosure 214 . The multi-fiber latch mechanism 220 is thus mated with both pins 414 and 416 , and the four-channel small package pluggable latch mechanism 216 is mated with pins 440 and 442 .

The optical transceiver assembly 150 can be removed from the housing 110 by pulling the handle 212 . The handle 212 moves the housing 210, and thereby the attached four-channel small package pluggable latch mechanism 216 and multifiber latch mechanism 220, to the retracted position and holds the spring 238 on the stop tab 310 and the rear plate 236 compressed between. By retracting the four-channel small package pluggable latch mechanism 216 and the multi-fiber latch mechanism 220, the multi-fiber fiber latch mechanism 220 is disengaged from the two pins 414 and 416, and the four-lane small package pluggable latch mechanism 216 is disengaged from pins 440 and 442.

FIGS. 4C-4D show the optical transceiver assembly 150 as the user pulls the handle 212 and housing 210 away from the rear plate 236 . Pulling the handle 212 causes the housing 210 to move the four-channel small form factor pluggable latch mechanism 216 and the multifiber latch mechanism 220 to a retracted position relative to the electronics enclosure 214 . As the four-channel small form factor pluggable latch mechanism 216 and the multifiber latch mechanism 220 are attached to the handle 212 and housing 210 , they move toward the rear plate 236 . The stop tab 310 of the housing 210 compresses the spring 238 against the rear plate 236 .

Movement of the four-way small package pluggable latch mechanism 216 within the electronics enclosure 214 to the retracted position disengages it from the pins 440 and 442 so that the four-way small package pluggable connector 218 is removed from the four-way small package pluggable connector 218. Package pluggable socket 122 off Leave. At the same time, the movement of the multifiber latch mechanism 220 within the electronic equipment housing 214 to the retracted position disengages the multifiber connector 222 from the multifiber receptacle 120 , disengaging it from the pins 414 and 416 .

Once the quad small package pluggable latch mechanism 216 and the multi-fiber fiber latch mechanism 220 are disengaged from the quad small package pluggable receptacle 122 and the multi-fiber fiber receptacle 120, the pulling force from the handle 212 causes the quad small package pluggable The extraction latch mechanism 216 and the multi-fiber latch mechanism 220 are fully retracted and the electronics enclosure 214 is removed from the optical receptacle 120 and electrical receptacle 122 . The optical transceiver assembly 150 can thus be completely removed, as shown in Figures 4E-4F. When the optical transceiver assembly 150 is completely removed, the handle 212 and housing 210 are no longer pulled away from the electronics housing 214 . The spring 238 thus returns to an unconstrained state, and the four-channel small package pluggable latch mechanism 216 and the multifiber latch mechanism 220 return to the extended position in the electronics enclosure 214 .

Reinserting the optical transceiver assembly 150 involves holding the handle 212 and pushing the quad small package pluggable latch mechanism 216 and the multifiber fiber latch mechanism 220 into the corresponding quad small package pluggable receptacle 122 and multifiber latch mechanism 220 Fiber receptacle 120 . The optical transceiver assembly 150 may be pushed forward toward the chassis 110 . The distance between the extended and retracted positions of the multi-fiber latch mechanism 220 is shorter than the distance between the extended and retracted positions of the four channel small package pluggable latch mechanism 216 . The multi-fiber connector 222 is flexible and thus can be compressed after the multi-fiber latch mechanism 220 is engaged with the multi-fiber receptacle 120 . The length of the expansion and retraction strokes of the multi-core fiber optic connector 222 matches the sliding distance of the gold finger connection in the four-channel small package pluggable connector 218 . Therefore, the pins 414 and 416 are first engaged with the multi-fiber latch mechanism 220 . The multi-fiber connector 222 is compressed as the optical transceiver assembly 150 is moved forward until the pins 440 and 442 engage the four-channel small package pluggable latch mechanism 216, as shown in FIGS. 4A-4B. with this In this way, the optical connection through the multi-core optical fiber socket 120 is performed first, and then the electrical signal connection through the four-channel small package pluggable socket 122 is performed. This ensures that the optical transceiver assembly 150 is designed so that the connection sequence of optical connections followed by electrical connections is automatically followed correctly.

FIGS. 5A-5B are top and top perspective views of an example optical transceiver assembly 150 showing the four-channel small package pluggable latch mechanism 216 and the multi-fiber latch mechanism 220 mated to the corresponding four-channel small package Pluggable socket 122 and multi-core fiber socket 120.

A transverse portion 514 engages the first arm portion 510 and the second arm portion 512 and holds electronics (not shown) that convert electrical signals to optical signals. The parallel inner walls of the first arm portion 510 allow the multi-fiber latch mechanism 220 to move between a retracted position and an extended position. Movement of the multi-fiber latch mechanism 220 away from the extended position is limited by the backstop 516 shown in Figure 5B. A portion of the 4-channel small package pluggable latch mechanism 216 extends outward from the second arm portion 512 to fit a mating 4-channel small package pluggable socket such as the 4-channel small package pluggable socket 122 . The parallel inner walls of the second arm portion 512 provide guidance for movement of the four-channel small package pluggable latch mechanism 216 between the extended and retracted positions. The stop tabs 310 of the housing 210, as shown in Figure 3A, contact corresponding stops formed on the bottom panel of the electronics housing 214, allowing the housing 210 and the attached four-channel small package to pluggable latch mechanisms 216 and the multi-fiber latching mechanism 220 are approaching Stop when the rear plate 236 .

As shown in close-up inset 520 in FIG. 5A and close-up inset 522 in FIG. 5B , multi-fiber receptacle 120 includes two pins 414 and 416 , each of which is defined at one end by hook member 530 . The multi-core fiber latch mechanism 220 includes an inner housing 532 having two opposing sides 534 and 536 . Side 534 and side 536 each have a notch 538 that fits the hook member 530 of the respective pin 414 and pin 416 . When the multifiber latch mechanism 220 is fully pushed into the multifiber receptacle 120 , the hook members 530 of the pins 414 and 416 mate with the notches 538 on the sides 534 and 536 of the inner housing 532 . The outer shell 540 of the multi-core fiber latch mechanism 220 encloses the inner shell 532 . Housing 540 includes parallel protrusions 542 and 544 extending from one end of housing 540 . When the multi-fiber latch mechanism 220 is in the extended position, the parallel tabs 542 and 544 are positioned on the pins 414 and 416 of the multi-fiber receptacle. In the extended position, parallel tabs 542 and 544 retain hook member 530 in recess 538 .

Similarly, as shown in close-up inset 550 in FIG. 5A and close-up inset 552 in FIG. 5B , receptacle 124 of quad small package pluggable receptacle 122 includes two prongs cut from respective sides of receptacle 124 440 and pin 442. Both pins 440 and 442 can thus bend inwardly from the sides of socket 124 . As shown in FIG. 5C , the second arm portion 512 includes two opposing sides 560 and 562 that retain the four-channel small package pluggable latch mechanism 216 . The four-channel small package pluggable latch mechanism 216 moves between the inner surfaces of the opposite side 560 and the opposite side 562, between an extended position and a retracted position. The outer surfaces of opposite side 560 and opposite side 562 include a groove 564 that defines a stop end 566 . A central groove 568 is formed in groove 564 . Guide tabs 260 and 262 of housing 210 include respective hook members 570 and 572 that fit within slots created between the inside surface of receptacle 124 and groove 564 . Hook member 570 and hook member Lateral movement of 572 stops against stop end 566 . The ends of hook member 570 and hook member 572 include a triangularly extending tab 574 that abuts stop end 566 . Hook member 570 and hook member 572 each have an elongated body including portions that fit within groove 564 and central groove 568 . Because of the grooves 564 and the central groove 568, the hook members 570 and 572 fit under the respective prongs 440 or 442 to allow the prongs 440 and 442 to flex inwardly and engage the respective hook members 570 and 442. Triangularly extending projection 574 of hook member 572 . Thus, when the four-way small package pluggable latch mechanism 216 is fully pushed into the four-way small package pluggable receptacle 122, the hook members 570 and 572 flex inwardly through the pins 440 and 442, and It is held in place in contact with the individual triangular extension tabs 574 .

When the handle 212 of the optical transceiver assembly 150 is pulled, the locking mechanism is unlocked between the optical receptacle 120 and the electrical receptacle 122 and the four-channel small package pluggable latching mechanism 216 and the multi-fiber latching mechanism 220, as shown in Figure 6A to Figure 6B. Similar elements are marked with the same symbols in Figures 6A to 6B as their counterparts in Figures 1 to 2. As shown in close-up inset 600 in FIG. 6A and close-up inset 602 in FIG. 6B, pulling handle 212 in FIG. 5A causes multifiber latch mechanism 220 to be pulled away from multifiber receptacle 120 and the electronics enclosure. 214. This causes the parallel tabs 542 and 544 of the housing 540 of the multi-fiber latch mechanism 220 to be pulled away from the pins 414 and 416 of the multi-fiber receptacle 120 . Once parallel tabs 542 and 544 are fully pulled away from pins 414 and 416 , as shown in inset 604 , pins 414 and 416 may flex outwardly, thereby allowing hook members 530 to move out of notches 538 . The beveled sides of the notch 538 force the hook members 530 of the prongs 414 and 416 out of the notch 538 when the multi-fiber latch mechanism 220 is pulled out. In this manner, the multi-fiber latch mechanism 220 can be detached from the multi-fiber receptacle 120 . As the handle 212 continues to be pulled, the multi-core fiber The latch mechanism 220 is pulled to the rear barrier 516 . Once the multi-fiber latch mechanism 220 contacts the rear barrier 516, the electronics housing 214 is also pulled along with the handle 212, allowing the complete optical transceiver assembly 150 to be pulled away.

Similarly, FIGS. 6C and 6D show close-up perspective views of the quad small package pluggable latch mechanism 216 disengaged from the quad small package pluggable receptacle 122 . As described above, the four-channel small package pluggable latch mechanism 216 is pulled back via the handle 212 to a retracted position relative to the electronics housing 214, as shown in Figure 5A. When the four-channel small package pluggable latch mechanism 216 is pulled back, the respective guide tabs 260 and the hook members 570 and 572 of the guide tabs 262 of the housing 210 are pulled away from the electronic device housing 214. The side portion 560 of the second arm portion 512 and the stop end portion 566 of each notch 564 on the side portion 562 are shown in FIG. 6C. When the hook member 570 and the hook member 572 are further pulled back, the triangular extension protrusion 574 is pulled back and pushes the pins 440 and 442 on the side of the receptacle 124 of the four-channel small package pluggable socket 122 toward the Bend outwards, thereby releasing the hook members 570 and 572 of the guide tabs 260 and 262 of the housing 210, as shown in Figure 6D. Since the triangular extension tabs 574 are no longer secured between the stop ends 566 and the pins 440 and 442, the four-channel small package pluggable latch mechanism 216 can move freely. The four-lane small package pluggable latch mechanism 216 can thus be disengaged from the four-lane small package pluggable receptacle 122, and both the second arm 512 and the four-lane small package pluggable latching mechanism 216 can be fully disengaged.

Since the first arm portion 510 and the second arm portion 512 of the electronic device housing 214 secure the four-channel small package pluggable latch mechanism 216 and the multi-fiber latch mechanism 220 in position relative to each other, the optical transceiver assembly The 150 allows connection to optical and electrical sockets without the use of cables.
