100G QSFP28 SR4 optical module as a new QSFP28 family one, short-distance transmission network is 100G in an ideal solution for 100G applications will more and more be put to practical environment. So 100G QSFP28 SR4 connection program is how well the application areas in which it easy to communicate to the sky for everyone announced.
Technological development 100G optical modules
Compared with 2.5G, 10G or 40G WDM transmission system, 100G optical transmission using digital coherent receiver by phase diversity and polarization diversity to map all of the optical properties of the optical signal to the electrical domain, the use of sophisticated digital signal processing in the electrical domain implementation of the polarization demultiplexing, channel impairments equalization compensation, timing recovery, carrier phase estimation, and symbol estimation linear decoding. In the transmission of light while achieving 100G, 100G optical module has undergone a series of major technological change, wherein the phase modulator comprises a polarization multiplexing technology and digital coherent receiving technology Super third generation error correction coding technology, thereby meeting the user when both into demand.
