QSFP28 SR4 optical module connection solution and application field

---

 As a member of the new QSFP28 family, the 100G QSFP28 SR4 optical module is a very ideal solution in the short distance transmission of 100g network. The application of 100G will be more and more put into the actual environment. So what is the connection solution of 100G QSFP28 SR4 and what fields are it applied in? ETU-Link will unveil it for you.

Technology development of 100G optical module

Compared with 2.5G, 10G or 40G WDM systems, 100G 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 100G optical transmission, a series of significant technical changes have taken place in 100G optical module, including polarization multiplexing phase modulation technology, digital coherent reception technology, the third generation of super strong error correction coding technology, etc., which meets the needs of users with the times.
