Abstract

The invention relates to the technical field of optical signal regeneration, and discloses a regenerator suitable for wavelength division multiplex-differential phase shift keying (WDM-DPSK) optical signals. The regenerator comprises a first pump laser, a second pump laser, a first polarization controller, a second polarization controller, a first coupler, a second coupler, a first medium, a second medium and a phase regulating module. The second pump laser is connected with an input end of the first polarization controller, and an output end of the first polarization controller is connected with the first coupler. An output end of the first pump laser is connected with an input end of the first coupler. An output end of the first coupler is connected with an input end of the second coupler. The optical signals are incident from an input end of the second polarization controller, an output end of the second polarization controller is connected with the input end of the second coupler, and an output end of the second coupler is connected with the second medium through the first medium. The phase regulating module is connected with two ends of the second medium. By means of the regenerator suitable for the WDM-DPSK optical signals, regeneration of the WDM-DPSK optical signals is achieved.

Description

technical field [0001] The invention relates to the technical field of optical signal regeneration, in particular to a regenerator suitable for WDM-DPSK optical signals. Background technique [0002] Since the appearance of optical fiber communication technology, the optical fiber communication system has maintained a rapid development. In recent years, with the increasing number of users using broadband and the extensive promotion of fiber-to-the-home (FTTH) services, people have higher and higher requirements for the traffic and bandwidth of the backbone network. At present, the actual transmission system uses optical signal of intensity modulation coding (OOK), the transmission capacity of a single channel has been upgraded from 2.5Gb / s to 40Gb / s, and the commercialization of 100Gb / s optical signal transmission system The application is also gradually advancing, and at the same time, 400Gb / s optical signal transmission has also received more and more attention. However,...
