Description

Technical Field

[0001] The utility model relates to the technical field of optical modules, in particular to a dual-fiber bidirectional transceiver integrated optical module. Background Art

[0002] A dual-fiber bidirectional optical module is a device used for optical fiber communication, which can convert electrical signals into optical signals and transmit them. This module uses two optical fibers for data transmission, one optical fiber is used to send data signals, and the other optical fiber is used to receive data signals. This design improves the stability and reliability of data transmission. A dual-fiber bidirectional optical module usually includes an integrated optical transceiver module, whose main function is to realize photoelectric conversion, including optical power control, modulation transmission, signal detection, IV conversion, and limiting amplification judgment regeneration. However, when the existing dual-fiber bidirectional optical module is connected to the optical fiber, the optical fiber is prone to bending. If the bending radius of the optical fiber is too small, the light will not be fully reflected at the interface between the core and the coating of the optical fiber, causing part of the light to leak out of the coating, resulting in incomplete signal transmission or transmission errors. Therefore, those skilled in the art provide a dual-fiber bidirectional transceiver integrated optical module to solve the problems raised in the above background technology. Utility Model Content
