Optical module

Abstract

The invention provides an optical module including a light receiving sub-module, a limiting amplifier LIA, and a filter. the light receiving sub-module receives the light signals carrying two signals and converts the light signals into electric signals, the input end of the filter is connected with the light receiving sub-module in order to filter the electric signals output from the light receiving sub-module to obtain a first signal, the LIA is connected with the light receiving sub-module to perform amplitude limit and amplification on the electric signals output from the light receiving sub-module and to obtain the second signal from the electric signals. The optical module realizes the separation of two signals.

Description

Technical field [0001] The present invention relates to the technical field of optical fiber communication, in particular to an optical module. Background technique [0002] In the optical communication network, the optical module realizes the conversion of optical signals into electrical signals. Specifically, the received optical signal is converted into an electrical signal through the Receiver Optical Sub-Assembly (ROSA for short) in the optical module. [0003] In the process of implementing the present invention, the inventor found that there are at least the following problems in the prior art: ROSA can only receive an optical signal containing a single channel of information, and for an optical signal containing two channels of information, the two channels of information cannot be separated. . Summary of the invention [0004] The invention provides an optical module to overcome the problem that the two channels of information cannot be separated in the prior art. [0005]...
