Title:
SINGLE-WAVELENGTH 100G LIGHT MODULE AND 5G FRONTHAUL NETWORK
Document Type and Number:
WIPO Patent Application WO/2020/103312
Kind Code:
A1
Abstract:
Disclosed a single-wavelength 100G light module. The light module comprises a light emitting unit and a light receiving unit; the light emitting unit receives a 100G/s-rate NRZ electrical signal, encodes and converts the 100G/s-rate NRZ electrical signal into a 50G/s-rate four-level electrical signal, and converts the 50G/s-rate four-level electrical signal into a 50G/s-rate PAM4 light signal and transmits same; the light receiving unit receives the 50G/s-rate PAM4 light signal, converts the 50G/s-rate PAM4 light signal into the 50G/s-rate four-level electrical signal, and decodes and converts the 50G/s-rate four-level electrical signal into the 100G/s-rate NRZ electrical signal and outputs same. The single-wavelength 100G light module of the present invention can support single-path 100Gb/s-rate transmission service, reduce the number of light devices in use, reduce the costs of the light module, and be completely compatible with the existing 100G switch interfaces.
