Example (b):

referring to fig. 1 to 4, the 86 panel optical fiber transceiver in the preferred embodiment of the present invention includes a bottom case 4 that can be embedded in the 86 bottom case, wherein the bottom case 4 is a box-shaped structure with an opening at one side, and a cavity for accommodating the circuit board assembly 3 is formed inside the bottom case 4. Accordingly, the upper cover 2 and the panel 1 are disposed corresponding to the opening side of the bottom case 4, and the circuit board assembly 3 can be packaged in the bottom case 4 by matching the upper cover 2 with the opening side of the bottom case 4, and a 86 panel structure is formed.

Specifically, the bottom case 4 in the preferred embodiment is not a regular square box structure, and has a multi-step structure formed on the outer peripheral wall surface thereof, as shown in fig. 1, and after the bottom case 4 is fittingly inserted into the bottom case 86, a space for accommodating the optical fiber plug 6 and the power plug 7 is formed between the inner wall surfaces of the bottom cases 4 and 86. Accordingly, through holes are respectively opened on the bottom case 4 corresponding to the optical fiber plug 6 and the power plug 7, and an optical module, i.e., BOSA305, for matching the optical fiber plug 6 is correspondingly provided in the bottom case 4, and a power input socket 306 for matching the power plug 7 is correspondingly provided in the bottom case 4.

In order to better save space inside bottom case 4, BOSA305 and power input socket 306 in the preferred embodiment are stacked in the axial direction of bottom case 4, as shown in fig. 1 and 2. Since BOSA305 tends to be larger in size than power input socket 306, power input socket 306 is preferably disposed at the bottom of bottom case 4, and the size of the space inside bottom case 4 increases from the bottom of bottom case 4 toward the opening side. Obviously, inside the bottom shell 4, a step structure is also formed, respectively for the placement of the corresponding components of the circuit board assembly 3.

As shown in fig. 2, the circuit board assembly 3 in the preferred embodiment is embedded in the bottom case 4, and is used for receiving and converting optical signals and electrical signals, and correspondingly outputting the converted signals to an optical switch or a terminal device. For example, an optical signal from an optical switch in a communication network (ethernet network) is received, processed into an electrical signal, and then output to a terminal device; or receiving the electric signal of the terminal equipment, converting the electric signal into an optical signal and outputting the optical signal to the optical switch.

In particular, the circuit board assembly 3 in the preferred embodiment comprises a main circuit board 301, which main circuit board 301 is horizontally housed in the bottom shell 4 and is provided with at least one network interface 304, such as the one shown in fig. 3, on its end face facing the open side of the bottom shell 4. Correspondingly, through holes are formed in the panel 1 and the upper cover 2 corresponding to the network interface 304, so that after the panel 1 and the upper cover 2 are matched on the bottom case 4, the network interface 304 can be communicated with the external environment of the panel 1, and network connection of external equipment is realized.

Preferably, a dustproof board assembly 5 is disposed on a side of the upper cover 2 opposite to the main circuit board 301 corresponding to the opening of the network interface 304, so that the dustproof board assembly 5 is exactly aligned with the corresponding network interface 304 after the circuit board assembly 3 is packaged in the bottom case 4 by the upper cover 2. The dust guard assembly 5 in the preferred embodiment includes a horizontally openable and closable closure plate that closes the network interface 304 when it is not operating and releases the closure when the network interface 304 is operating.

In more detail, the network interface 304 in the preferred embodiment is an RJ45 network interface. Meanwhile, in the preferred embodiment, the network interfaces 304 on the main circuit board 301 may also be arranged in multiple numbers as required, for example, two networks arranged side by side, three networks distributed in a triangular manner, four networks distributed in a grid pattern, etc., so as to meet different setting requirements.

Further, a power circuit board 302 is disposed on a side of the main circuit board 301 away from the network interface 304, and is used for processing an input voltage to supply power to the photoelectric receiver. In order to save the accommodation space in the bottom case 4, a BOSA305 for connecting the optical fiber plug 6 and a power input socket 306 for connecting the power plug 7 are respectively disposed on one side of the power circuit board 302, as shown in fig. 2. Obviously, the size of the power circuit board 302 is smaller than that of the main circuit board 301.

Meanwhile, the power input socket 306 is electrically connected with the power circuit board 302 through a conducting wire, and the power circuit board 302 is electrically connected with the main circuit board 301 through a conducting wire, so that the introduced electric energy can complete voltage conversion at the power circuit board 302 without supplying power to all parts on the main circuit board 301.

In actual installation, at least one optical fiber transceiver chip 303 is further disposed on the main circuit board 301, and is configured to process an input optical signal, convert the optical signal into an electrical signal, and output the electrical signal via the network interface 304. The optical fiber transceiver chip 303 may be disposed on the front side (the side where the network interface 304 is disposed) or the back side (the side opposite to the power circuit board 302) of the main circuit board 301 according to the actual installation requirement.

When the network interface 304 on the main circuit board 301 is set to be one, the workload pressure of the optical transceiver chip 303 is small, and the heat generated by the operation of the optical transceiver chip is also low, and the heat can be dissipated by forming heat dissipation holes on the periphery of the bottom case 4 and/or the periphery of the panel 1.

However, when the network interface 304 on the main circuit board 301 is provided in plural, it is necessary to provide a fiber transceiver chip 303 with larger power or provide a plurality of fiber transceiver chips 303, and the workload of the fiber transceiver chip 303 is also increased significantly, and the amount of heat generated during operation is also increased significantly. Because the heat generation and accumulation are mainly concentrated near the optical fiber transceiver chip 303, different parts on one side of the main circuit board 301 have uneven temperature, or obvious temperature difference exists on the front side and the back side of the main circuit board 301, so that the main circuit board 301 is likely to be bent and deformed, and the problems of part of components damage, welding leg falling and the like are caused, thereby affecting the normal work and the service life of the optical fiber transceiver.

In this regard, in the preferred embodiment, a sub circuit board 307 is further provided corresponding to the optical fiber transceiver chip 303, as shown in fig. 5, which is provided between the main circuit board 301 and the upper cover 2, has a size smaller than that of the main circuit board 301, and is correspondingly provided in the space on the side of the network interface 304, making full use of the internal space of the bottom case 4 vacated by the arrangement of the network interface 304. Accordingly, a plurality of network interfaces 304 are arranged side by side on one side of the main circuit board 301.

Further preferably, in order to improve the heat dissipation effect of the secondary circuit board 307, a heat dissipation plate is disposed on a side of the upper cover 2 facing the secondary circuit board 307, so that heat generated on the secondary circuit board 307 can be quickly absorbed by the heat dissipation plate, thereby reducing the temperature on the secondary circuit board 307. Correspondingly, heat dissipation holes are formed in the two sides of the bottom shell 4 and/or the panel 1 respectively, so that the heat dissipation holes can be horizontally aligned with the heat dissipation plate after the panel 1 is matched with the bottom shell 4, and then the heat can be quickly dissipated.

By utilizing the arrangement, the space of the bottom shell 4 on one side of the network interface 304 and one side of the power circuit board 302 can be fully utilized, the effective arrangement of each part in the bottom shell 4 is realized while the use function of the optical fiber transceiver is ensured, and further, the possibility is provided for the arrangement and the use of the optical fiber transceiver in the 86-type bottom box.

The 86 panel type optical fiber transceiver is simple in structure and convenient to set, the arrangement form and the arrangement position of each component of the circuit board assembly are optimally designed, the internal space in the bottom shell is fully utilized, the bottom shell can be accurately matched with the 86 type bottom box and the arrangement is completed, the 86 type design of the optical fiber transceiver is effectively realized, the use of the optical fiber transceiver is simplified, the use convenience and the attractiveness of the optical fiber transceiver are improved, the 86 panel type optical fiber transceiver has very important promoting significance on the transformation of the existing network line, and the 86 panel type optical fiber transceiver has great application prospect in the design of a small-sized optical fiber communication system.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the utility model, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
