Problems solved by technology

[0002] With the development of society, people's requirements for information transmission continue to increase, from cables to optical fibers; and the current communication requirements are getting higher and higher. When the transmission volume is large, multiple optical fibers are required, resulting in bloated transmission lines; secondly , when optical fiber resources are insufficient, users also hope to transmit more signal volume through fewer optical fibers to reduce the usage of optical fibers; therefore, it is urgent to develop an optical module that can realize multiplexing and demultiplexing

Abstract

The invention relates to the field of photoelectric communication, in particular to a WDM optical module and a manufacturing method. A WDM optical module comprises a PCB, the PCB is provided with a PLC chip, the lower end of the left side of the PLC chip is provided with an installation port, the PCB is provided with n optical signal processing units 5 in the installation port, each optical signalprocessing unit 5 comprises t VCSELs and f PDs, t + f = n, n is a natural number larger than 1, and t and f are larger than or equal to 0 and smaller than or equal to 1; a filter assembly is arrangedin the middle of the PLC chip and comprises n filters in one-to-one correspondence with the mounting positions; the PCB is provided with an optical fiber interface at the right end of the PLC chip. By arranging the PLC chip and the filter plate, multiple paths of optical signals can be combined and shunted.

Description

technical field [0001] The invention relates to the field of photoelectric communication, in particular to a WDM optical module and a manufacturing method. Background technique [0002] With the development of society, people's requirements for information transmission continue to increase, from cables to optical fibers; and the current communication requirements are getting higher and higher. When the transmission volume is large, multiple optical fibers are required, resulting in bloated transmission lines; secondly , when optical fiber resources are insufficient, users also hope to transmit more signal volume through fewer optical fibers to reduce the usage of optical fibers; therefore, it is urgent to develop an optical module that can realize multiplexing and demultiplexing. Contents of the invention [0003] The purpose of the present invention is to provide a WDM optical module for the deficiencies of the prior art. The WDM optical module has the functions of multip...
