Description

OPTICAL TRANSCEIVER FOR CONNECTING AN APC OPTICAL FIBER}

The present invention relates to a receptacle included in an optical transceiver, and more particularly, to an optical transceiver receptacle capable of connecting an angled physical contact (APC) type optical fiber to the optical transceiver.

An optical transceiver is a communication module that performs optical-to-electric conversion and all-optical conversion in an optical communication device. The optical transceiver converts an electric signal to be transmitted through an optical fiber into an optical signal and outputs the optical signal or receives an optical signal received from the optical fiber. It converts into electric signal and transmits to host. As the speed of optical communication devices increases, the optical transmission speed of optical transceivers is also increasing to more than 10 Gb / s, and the size of modules is becoming smaller and smaller.

On the other hand, the recent optical transceiver includes a latch configuration for the pluggable property in order to be easily detached and coupled with the host. Accordingly, the optical fiber and the optical transceiver are configured to be easily connected and detached.

On the other hand, a conventional optical fiber is formed in the form of a physical contact (PC), the angle of the contact surface between the optical fiber and the optical fiber or the optical fiber and ferrule (ferrule) has an angle of 90 ° relative to the plane. That is, the contact surface of the optical fiber has a flat structure. However, in such a configuration, even if the optical axes of the optical fibers or ferrules in contact are well aligned, a problem may occur in which fine reflection of light is generated at the contact surface.

In order to reduce such minimum reflection, a method using an APC type optical fiber having a predetermined angle at a contact surface is known. The angle of the contact surface between the optical fiber and the optical fiber or between the optical fiber and the ferrule is formed to have an oblique angle rather than 90 ° with respect to the plane.

However, the APC type structure has a problem that it is very difficult to accurately align the optical axis of the optical fiber or ferrule. Therefore, in order to selectively detach and couple the optical fiber of the APC type structure to the optical transceiver, it is necessary to improve the configuration of the optical transceiver so that the optical axis of the optical fiber or ferrule can be accurately aligned. In particular, there is a need for an optical transceiver having a configuration capable of accurately aligning the direction of an APC type optical device in the production process of the optical transceiver.

Some embodiments of the present invention provide an optical transceiver that can easily perform coupling and detachment of an APC type optical device.

In addition, some embodiments of the present invention provide an OSA module configured to facilitate assembly of an optical transceiver capable of connecting an APC type optical element.

As a technical means for achieving the above technical problem, the optical subassembly (OSA) module according to the first aspect of the present invention is a sleeve in which an Angled Physical Contact (APC) type optical element is inserted, which displays the protruding direction of the APC optical element And an optical receiver for converting an optical signal received through the direction display unit and the APC optical element into an electrical signal.

In addition, the optical subassembly (OSA) module according to the second aspect of the present invention converts an sleeve into which an Angled Physical Contact (APC) type optical element is inserted, a direction indicator indicating the protruding direction of the APC type optical element, and converts an electrical signal into an optical signal. And an optical transmission device for transmitting to the APC optical device.

In addition, the optical transceiver for the connection of the APC (Angled Physical Contact) optical device according to the third aspect of the present invention is inserted into the APC-type optical device according to a predetermined projection direction, OSA displayed the projection direction of the inserted APC optical device (Optical Subassembly) module, comprising a hooking connection for coupling with the OSA module, the hooking connection for coupling an external optical fiber connector to the OSA module and a housing for storing the OSA module and hooking connection, wherein the housing is a predetermined position And the fixed hooking connection secures the OSA module to a preset position.

In addition, the optical transceiver for the connection of the APC (Angled Physical Contact) optical device according to the fourth aspect of the present invention is inserted into the APC-type optical device in accordance with a preset projection direction, OSA displayed the projection direction of the inserted APC optical device (Optical Subassembly) module, comprising a housing for storing the OSA module, wherein the housing fixes the OSA module in a predetermined position.

According to the aforementioned problem solving means of the present invention, the optical axis alignment between the APC type external optical element and the APC type optical element included in the optical transceiver can be easily performed. In particular, in the assembly process of the optical transceiver, the OSA module including the APC-type optical device can be fixed in a state where the user maintains a high degree of precision, and thus the optical axis alignment between the APC-type optical devices can be easily performed. . As a result, the use of an APC type optical element is also sufficiently possible for an optical transceiver having a pluggable characteristic.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is "connected" to another part, this includes not only "directly connected" but also "electrically connected" with another element in between. . In addition, when a part is said to "include" a certain component, which means that it may further include other components, except to exclude other components unless otherwise stated.

1 is a diagram illustrating a commonly used OSA optical transceiver.

The illustrated optical transceiver 100 includes an OSA module 110, a hooking connection 120, a housing 130, and a PCB board 140.

The OSA module 110 may include an optical transmitter 112 or an optical receiver 114 or may include both an optical transmitter 112 and an optical receiver 114. In the case of including the light transmitter 112 and the light receiver 114, the positions of the light transmitter 112 and the light receiver 114 may be interchanged according to embodiments. When the OSA module 110 includes only the optical transmitter, it is called TOSA (Transmitter Optical SubAssembly). When the OSA module 110 includes only the optical receiver, it is called a Receiver Optical SubAssembly (ROSA).

In general, the OSA module 110 includes an optical device such as a PC type optical fiber or a ferrule.

The hooking connection 120 is inserted into the OSA module 110, fixed by the housing 130, and the optical fiber connector 200 inserted through the opening 150 of the housing 130 is connected to the optical transceiver 100. To be fixed.

In the optical transceiver 100 of such a conventional configuration, when the PC-type optical element included in the OSA module 110 is simply replaced by an APC-type optical element, the optical element and the OSA module 110 included in the APC-type optical fiber connector 200. Accurate alignment of the optical elements included in may be difficult. The connection between the APC type optical elements will be described with reference to the drawings.

2 is a view for explaining the connection between optical elements of the APC type structure.

As shown in (a), in the case of the PC type structure, the cross section of the optical fiber or the ferrule is configured to be perpendicular to the plane, respectively. However, in the case of the APC type structure, as shown in (b), the cross section of each optical element is configured such that a predetermined angle θ, for example, an angle of about 8 ° is formed with respect to the vertical plane. Here, the optical element is defined as a configuration including an optical fiber or ferrule.

Therefore, in the case of (a), when the optical devices 30 and 31 are advanced in a specific direction (for example, Z direction) such that the optical devices 30 and 31 face each other, optical alignment between the optical axes may be completed. have. However, in the case of (b), since a predetermined angle is formed, there is a difficulty in that the X direction and the Y direction are perfectly matched in addition to the Z direction. That is, the point 34 having the maximum height with respect to the optical axis 38 in the optical device 32 and the point 37 having the lowest height with respect to the optical axis 39 in the optical device 33 coincide with each other. Align the optical axis in such a way that the point 36 at the height 36 with respect to the optical axis 39 in the element 33 coincides with the point 35 with the lowest height with respect to the optical axis 38 in the optical element 32. can do. Therefore, the optical axes may be aligned based on the position of the point protruding to the maximum from each optical element 32 or 33 or the direction in which each optical element protrudes.

 In the case of (c), the optical axis of the optical element and a part of its periphery are left while the taper is processed. As in the case shown in (a), when the optical devices 40 and 41 are advanced in the Z-axis direction, the optical alignment can be completed. However, in the case of (d), as in the case of (b), a specific direction must be aligned for optical axis alignment. That is, the point 44 having the maximum height with respect to the optical axis 48 of the optical device 42 and the point 47 having the lowest height with respect to the optical axis 49 of the optical device 43 match with each other. Align the optical axis in such a way as to match the point 46 with the maximum height relative to the optical axis 49 in the element 43 and the point 45 with the lowest height relative to the optical axis 48 in the optical element 42. can do.

As described above, in the case of the APC optical device, the optical axis must be aligned in a specific direction, and thus, the design of the optical transceiver that can guarantee the accuracy thereof is necessary.

3 is a diagram illustrating an optical transceiver to which the present invention is applied.

The illustrated optical transceiver 300 includes an OSA module 310, a hooking connection 320, a housing 330 and a PCB board 340.

The OSA module 310 includes an optical transmitter 312 and an optical receiver 314, but the positions of the optical transmitter 312 and the optical receiver 314 may be interchanged according to embodiments. In addition, the OSA module 310 includes an optical element connecting portion 316 including an APC optical element such as an APC type optical fiber or an APC type ferrule, and a direction display unit 317 indicating a protruding direction of the APC optical element. The detailed configuration of the OSA module 310 will be described later with reference to the drawings.

The hooking connection 320 is inserted into the OSA module 310, fixed by the housing 330, and an optical fiber connector 200 inserted through the opening 350 of the housing 330 to the optical transceiver 300. To be fixed.

At this time, the hooking connection 320 is fixed in the X-axis, Y-axis and Z-axis movement by the structure of the housing 330. In addition, the hooking connection 320 is not only inserted into the OSA module 310, but also includes an OSA coupling part 324 for coupling with the OSA module 310.

A detailed configuration of the hooking connection 320 will be described later with reference to the drawings.

The housing 330 stores and fixes the OSA module 310 and the hooking connection 320. The hooking connecting portion 320 is fixed using the first to fourth walls 331, 332, 333, and 334. In addition, the flanges 319 of the OSA module 310 are stored using the fifth and sixth walls 335 and 336 to limit the movement in the Z direction of the OSA module 310.

Through the drawings, the configuration of the hooking connection 320 and the housing 330 will be described in detail.

4 is a diagram illustrating a configuration of a hooking connection unit according to an exemplary embodiment of the present invention.

The illustrated hooking connection 320 includes a body portion 322, an OSA coupling portion 324, first and second hooking portions 326 and 328, and an OSA insert 329. The housing 330 also includes first to fourth walls 331, 332, 333, 334 for fixing the hooking connections 320.

First, the body portion 322 is inserted into a space formed by the first and second walls 331 and 332 and a space formed by the third and fourth walls 333 and 334 to move in the Z-axis direction. This is limited. At this time, the first and second walls 331 and 332 and the third and fourth walls 333 and 334 are disposed to face each other.

In addition, the flange of the OSA module 310 (not shown) in a space formed by the fifth wall 335 protruding more than the first wall and the sixth wall 336 protruding more than the second wall in the Z-axis direction. ) Is inserted to restrict movement of the OSA module 310 in the Z-axis direction.

In addition, the width of the body portion 322 in accordance with the width (W1) of the housing 330, so that the body portion 322 is coupled to the housing 330, limiting the movement in the Y-axis direction of the hooking connection portion 320 do. In addition, the movement in the X-axis direction may be further limited by the first and second fixing parts 362 and 364 formed on the cover 360 of the housing 330. In this way, the hooking connection 320 is coupled to the housing 330, the movement in the X-axis, Y-axis and Z-axis direction is limited.

The first and second hooking portions 326 and 328 are formed to have an appropriate elasticity to allow free detachment of the optical fiber connector 200.

The OSA insertion hole 329 is inserted into the sleeve of the OSA module 310, thereby facilitating the coupling with the optical fiber connector 200.

The OSA coupling unit 324 is coupled to the OSA module 310 to allow the OSA module 310 and the hooking connection 320 to be fixed. The OSA coupling unit 324 is configured to fit the shape of the OSA module 310.

 According to this configuration, since the OSA module 310 is almost integrally coupled to the hooking connection 320, it is determined whether the OSA module 310 is moved by the movement state of the hooking connection 320. However, as described above, since the hooking connection part 320 is restricted in movement in the X-axis, Y-axis, and Z-axis directions in relation to the housing 330, the OSA module 310 also includes the X-axis, the Y-axis, and the like. Movement in the Z-axis direction is limited. In the conventional case, since there is no configuration similar to the OSA coupling portion 324, even if the OSA module 310 is inserted into the OSA insertion hole 329, its movement could not be completely limited.

Now, the configuration of the OSA module 310 will be described in detail.

The illustrated OSA module 310 includes an optical transmitter 312, an optical receiver 314, an optical device connector 316, a direction indicator 317, and a body 318. In this case, the OSA module 310 may include any one of the optical transmitter 312 and the optical receiver 314 or include both the optical transmitter 312 and the optical receiver 314. That is, the OSA module 310 may be TOSA, ROSA or BOSA.

The optical element connecting portion 316 optically contacts the APC optical element of the APC optical fiber connector 200 inserted from the outside with the APC optical element in the optical element connecting portion 316. A detailed configuration of the optical device connecting portion 316 will be described.

The direction display unit 317 displays the protruding direction of the APC optical element inserted into the optical element connecting portion 316. It may be displayed at a specific position of the optical device connecting portion 316 to display a point having a maximum height based on the optical axis or a point having a minimum height based on the optical axis. The direction indicator 317 is displayed, so that the worker assembling the optical transceiver can proceed with the assembly work much faster.

7 and 8 are views showing the detailed configuration of the optical element connecting portion, Figure 9 is a view showing the connection state of the optical element connecting portion and the OSA coupling portion.

(a) is a figure which shows one side surface of an optical element connection part, (b) is sectional drawing which cut | disconnected the optical element connection part in the 1-1 'direction, and (c) is sectional drawing which cut | disconnected the optical element connection part in the 2-2' direction. (d) is a perspective view of an optical element connection part, and FIG. 8 is an exploded view of the optical element connection part.

The optical element connecting portion 316 includes an APC type optical element 610, an inner sleeve 620, an outer sleeve 630, and a fixing ring 650, and specifies the direction of the APC type optical element 610.

The APC type optical element 610 is fixed in a state of being inserted into the inner sleeve 620 and the outer sleeve 630. In this case, the APC type optical device 610 has an APC form in which both one end 612 and the other end 614 inserted into the OSA module 310 are in contact with the external optical fiber connector 200. To this end, the PC type optical device may be inserted into the inner sleeve 620 and the outer sleeve 630 after being polished by the APC optical device.

Alternatively, in the case of the other end 614, the optical device may be inserted into the inner sleeve 620 and the outer sleeve 630, and may have an APC shape through a polishing process. That is, an APC type optical element is formed through a process of grinding the end portion of the PC type optical element to have a predetermined angle. As such, when the polishing process is performed after the insertion of the PC-type optical device, the APC-type optical device may be formed according to a predetermined direction, and thus more precise processing may be possible.

The inner sleeve 620 fixes the APC type optical element 610 and is inserted into the outer sleeve 630. The inner sleeve 620 may be formed using zirconia (ZrO ₂ ), and as shown, is formed in the form of a tube having a predetermined thickness. In this case, the inner sleeve 620 may be formed in a form in which a part of the side is open.

The outer sleeve 630 guides the optical elements of the optical fiber connector 200 to contact the APC type optical elements 610 therein. The outer sleeve 630 also includes a first flange 640, a second flange 642, a flange coupling portion 644, and one or more direction keys 646.

The first flange 640 is formed on the outer circumferential surface of the outer sleeve 630 such that its diameter is greater than the diameter of the outer sleeve 630 based on the central axis of the outer sleeve 630 and has a predetermined thickness. It is fixed at, limiting the movement of the OSA module 310 in the Z direction. That is, the first flange 640 in the space formed by the first wall 331 and the fifth wall 335 of the housing 330 and the space formed by the second wall 333 and the sixth wall 336. ) Is stored, the movement of the OSA module 310 is limited. In addition, in the present invention, the flange coupling portion 644 is formed on a portion of the first flange 640 so that the OSA module 310 is coupled to the hooking connection 320 including the sleeve coupling portion 644.

The second flange 642 is formed on the outer circumferential surface of the outer sleeve 630 such that its diameter is smaller than the diameter of the first flange 640 based on the central axis of the outer sleeve 630 and has a predetermined thickness. It is formed adjacent to 640, and a flange coupling portion 644 is formed in a portion of the second flange 642, so that the OSA module 310 is coupled. In this case, the diameter of the second flange 642 may be the same as the outer sleeve 630.

The flange coupling portion 644 is formed to have a planar shape across the first flange 640 and the second flange 642. In this case, the plane may be two or more. That is, as illustrated in FIG. 7A or 9, two planes may be formed at positions facing each other to configure the first and second flange coupling parts 644 and 645. In this case, the OSA coupling portions 324 and 325 coupled to the flange coupling portions 644 and 645 are also configured in two planar forms. That is, the first OSA coupler 324 in contact with the first flange coupler 644 and the second OSA coupler 325 in contact with the second flange coupler 645 are configured. At this time, the distance W between the OSA coupling portions 324 and 325 facing each other is set to be equal to the distance between the flange coupling portions 644 and 645 facing each other, so as to contact the flange coupling portions 644 and 645. The spacing of the OSA coupling units 324 and 325 is minimized. That is, the OSA module 310 is coupled to the hooking connection 320 so that the flow is minimized.

In addition, one or more direction keys 646 are formed to display the protruding direction of the APC type optical element 610. At this time, the direction key 646 is configured in a protruding shape, the groove 652 is formed in the fixing ring 650, so that the direction key 646 is inserted into the groove 652.

At this time, the direction key 646 and the flange coupling portion 644 may be formed adjacent to each other, so that the flange coupling portion 644 itself can be configured to display the protruding direction of the APC optical device.

As such, by using the hooking connection part 320 fixed by the housing 330, the OSA module 310 is fixed so as not to move in the X-axis, Y-axis, and Z-axis directions, thereby including an APC type optical element. The 310 can be fixed to a preset position. Through such a configuration, even when various PCB boards are connected to the OSA module 310, it is possible to accurately fix the position in advance by the designer. In addition, by configuring the projection direction of the APC on the OSA module itself, it is possible to improve the working accuracy and speed of the operator.
