Description

technical field [0001] The embodiments of the present application relate to the technical field of optical communication, and more specifically, relate to an optical module, a ferrule, and an optical fiber connector. Background technique [0002] With the advancement of information technology and the needs of network applications, single-fiber bidirectional optical modules are widely used in communication networks because they can save one fiber resource and improve the capacity of communication systems compared with traditional dual-fiber bidirectional optical modules. . like image 3 As shown, when the single-fiber bidirectional optical module is applied to the communication between the baseband processing unit (baseband unit, BBU) and the active antenna unit (active antenna unit, AAU), it may appear that the multiplexer and demultiplexer receive through fiber #1 at the same time The optical signal and the situation of sending the optical signal cause conflicts.

Problems solved by technology

like image 3 As shown, when the single-fiber bidirectional optical module is applied to the communication between the baseband processing unit (baseband unit, BBU) and the active antenna unit (active antenna unit, AAU), it may appear that the multiplexer and demultiplexer receive through fiber #1 at the same time The optical signal and the situation of sending the optical signal cause conflicts. Therefore, the single-fiber bidirectional optical module cannot be applied to the scene directly connected to the multiplexer / demultiplexer

In addition, if the communication system needs to expand to a larger capacity, the single-fiber bidirectional optical module may not be able to meet the demand for capacity expansion
