Description

Technical Field

[0001] This utility model relates to the field of optical module technology, specifically to an optical module based on a silicon photonic chip. Background Technology

[0002] An optical module consists of optoelectronic devices, functional circuits, and optical interfaces. The optoelectronic devices include both transmitting and receiving parts. Simply put, the function of an optical module is to convert electrical signals into optical signals at the transmitting end, transmit them through optical fiber, and then convert the optical signals back into electrical signals at the receiving end. Optical modules are classified according to their packaging form; common types include SFP, SFP+, SFF, and Gigabit Ethernet Interface Converters (GBIC). The transmitting part works by: receiving an electrical signal of a certain bit rate, processing it through an internal driver chip, and then driving a semiconductor laser (LD) or light-emitting diode (LED) to emit a modulated optical signal at a corresponding rate. It also includes an internal automatic optical power control circuit to keep the output optical signal power stable.

[0003] The receiving section consists of an optical signal input module with a certain bit rate, which is then converted into an electrical signal by a photodetector diode. After passing through a preamplifier, it outputs an electrical signal with the corresponding bit rate. The main function of the optical transceiver module is to realize photoelectric / electro-optical conversion, including optical power control, modulation and transmission, signal detection, IV conversion, and limiting amplification decision regeneration functions. In addition, it also has functions such as anti-counterfeiting information query and TX-disable. Common types include SFP, SFF, SFP+, GBIC, XFP, and 1x9.

[0004] In addition to photoelectric conversion, optical repeater modules integrate numerous signal processing functions, such as MUX / DEMUX, CDR, function control, energy acquisition, and monitoring. Common optical repeater modules include 200 / 300-pin, XENPAK, and X2 / XPAK modules.

[0005] An optical transceiver module, also known as an optical module or fiber optic module, is a crucial component in fiber optic communication systems. D / T stands for datacom / telcom. Data communication primarily includes computer video and other data communication applications. Telcom mainly includes wireless voice communication.

[0006] These products are mostly used in the backbone network of fiber optic networks.

[0007] PON stands for Passive Optical Network. These products are primarily used in access networks within fiber optic network systems. Triplex products can transmit fiber optic signals as well as output analog signals. Optical modules are mainly categorized as GBIC, SFP, SFP+, XFP, SFF, and CFP, with optical interface types including SC and LC. However, SFP, SFP+, and XFP are now more commonly used than GBIC. This is because GBIC is bulky and prone to failure, while the commonly used SFP is smaller and cheaper.

[0008] Types: Single-mode optical modules are suitable for long-distance transmission; multi-mode optical modules are suitable for short-distance transmission. Function: Optical modules are used as carriers for transmission between switches and devices. Compared with transceivers, they are more efficient and secure. Optical modules can have built-in silicon photonics chips to increase their performance. Currently, when silicon photonics chip-based optical modules are installed on devices, the snap-fit ​​structure is prone to breakage during disassembly and assembly due to the snap-fit ​​method, which affects the robustness of the optical module. Utility Model Content

[0009] The purpose of this invention is to provide an optical module based on silicon photonics chips, which solves the problem that current optical modules based on silicon photonics chips are prone to breakage during installation and disassembly due to the snap-fit ​​method, thus affecting the robustness of the optical module.

The inner top wall of the docking groove has a movable groove, and the inner top wall of the movable groove is fixedly connected to a telescopic structure.

When the auxiliary plate is pulled upward, the auxiliary plate moves the optical module mounting block structure into the movable groove via the moving rod. Then, the optical module body is snapped into the mounting hole, so that the left side of the optical module mounting fixing hoop structure contacts the right side of the outer shell of the equipment. Then, the auxiliary plate is released, and the telescopic structure pushes the optical module mounting block structure to move and snap into the snap-fit ​​groove, thereby completing the installation of the optical module body.

[0012] Furthermore, the surface of the optical module mounting block structure is movably connected to the interior of the movable slot.

[0013] Furthermore, the right side of the outer casing of the device is provided with a through hole that communicates with the interior of the movable groove, and a movable rod is movably connected inside the through hole.

[0014] Furthermore, an auxiliary plate is fixedly connected to the right end of the movable rod, and the left side of the auxiliary plate overlaps with the right side of the outer casing of the equipment.

[0015] Furthermore, the left end of the movable rod is fixedly connected to the right side of the optical module mounting block structure.

[0016] Furthermore, the optical module mounting pin structure has two components, which are symmetrically arranged about the central axis of the optical module body.

[0017] This invention provides an optical module based on a silicon photonics chip. It has the following advantages:

[0018] This silicon photonics chip-based optical module achieves more convenient installation through the cooperation of docking slots, optical module mounting pin structures, snap-fit ​​slots, movable slots, telescopic structures, optical module mounting block structures, through holes, moving rods, and auxiliary boards. At the same time, it eliminates concerns about the traditional snap-fit ​​structure breaking and affecting the optical module's robustness. This solves the problem that currently, when installing silicon photonics chip-based optical modules on equipment, the snap-fit ​​structure is prone to breakage during disassembly and assembly, thus affecting the optical module's robustness.
