100G QSFP28 SR4 optical module connection solution
As a member of the new QSFP28 family, the 100 G QSFP28 S R 4 optical module is a very ideal solution in the short distance transmission of 100g network. The application of 100 G will be more and more put into the actual environment. So what is the connection solution of 100 G QSFP28 S R 4 and what fields are it applied in? ETU-Link will unveil it for you. Technology development of 100 G optical module Compared with 2.5G, 10 G or 40 G WDM systems, 100 G optical transmission uses digital coherent receiver to map all optical attributes of optical signal to the electric domain through phase diversity and polarization state diversity. Using mature digital signal processing technology, polarization demultiplexing, channel damage equalization compensation, timing recovery, carrier phase estimation, symbol estimation and linear decoding are realized in the electric domain. While realizing 100 G ...
