Abstract

The embodiment of the invention relates to the field of optical communication, in particular to a 1 * N type Twins wavelength selective switch device. The device comprises an input and output device,a Twins separation device, a first adjustment assembly, a dispersion device, a second adjustment assembly, a deflection device and a deflection conversion device, wherein the input and output device comprises a first input and output assembly and a second input and output assembly, the first input and output assembly is used for inputting and outputting Twins1 optical signals, and the second inputand output assembly is used for inputting and outputting Twins2 optical signals; and the Twins separation device is used for forming separation between the input Twins 1 optical signal and the inputTwins 2 optical signal. The device has the advantages that the same device packaging and control system can be adopted, the Twins1 optical signals and the Twins2 optical signals are processed at the same time, the height of the optical path is reduced, the structure is more compact and installation and adjustment are simpler.

Description

technical field [0001] The embodiment of the present invention relates to the field of optical communication, and in particular to a 1×N type Twins wavelength selective switch device. Background technique [0002] The wavelength selective switch (WSS) is an important optical component of the wavelength division multiplexer, and it is also the core component device for constructing the optical mesh network and the reconfigurable optical add-drop multiplexer (ROADM). Wavelength division multiplexing (WDM) optical signal, and output the signal to any output port. Usually, an optical network node needs to be equipped with multiple wavelength selective switches, which puts great pressure on the operator's cost and cabinet space. [0003] The Twins wavelength selective switch is based on a single wavelength selective switch device, by adding a small number of components to realize at least two sets of mutually independent wavelength selective switch devices. At present, the Twin...
