Multi-channel high-density wavelength division multiplexing high-speed optical device

Abstract

The invention discloses a multi-channel high-density wavelength division multiplexing high-speed optical device. The optical device comprises a laser module, an optical path conversion module, a wavelength division multiplexing module, an optical fiber coupling module and an optical fiber which are sequentially arranged along the optical axis direction. The optical device is characterized in thatthe wavelength division multiplexing module comprises a first Z-Block module with four channels and a second Z-Block module with four channels; eight paths of divergent light emitted by the laser module are converted into eight paths of parallel light through the light path conversion module; and eight paths of parallel light are divided into two groups according to four paths as a group, one group of coupled light passes through a first Z-Block module and then is combined into one path, the other group of coupled light passes through a second Z-Block module and then is combined into a secondpath, and two paths of light from the first Z-Block module and the second Z-Block module pass through a wave combining module and then are combined into one path. The multi-channel high-density wavelength division multiplexing high-speed optical device can greatly shorten the optical path.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a high-speed optical device with multi-wavelength division multiplexing function. Background technique [0002] With the upgrading of communication systems and the rapid growth of the demand for communication bandwidth, the existing communication systems are facing two challenges of capacity and energy consumption. Optical modules are required to provide greater bandwidth in a smaller space and lower energy consumption. [0003] Generally, an optical module with a wavelength division multiplexing function includes an optical platform and a wavelength division multiplexing optical component. At present, there are many designs of Z-Block modules for four channels on the market, but when they are extended to eight channels, if an eight-channel Z-Block module is used, the last two or three channels will inevitably encounter too many reflections due to the long optical ...
