As a member of the emerging QSFP28 family, 100G QSFP28 SR4 optical module is a very ideal solution for short-distance transmission in 100G network. 100G applications will be put into the actual environment more and more. So what is the connection scheme of 100G QSFP28 SR4 and in which areas is it applied? Yi Tianguang Communications will reveal it for you.

Technical Development of 100g Optical Module

Compared with 2.5G, 10G or 40G wavelength division transmission systems, 100G optical transmission uses a digital coherent receiver to map all optical properties of optical signals to the electrical domain through phase diversity and polarization diversity. Mature digital signal processing techniques are used to realize polarization demultiplexing, channel damage equalization compensation, timing recovery, carrier phase estimation, symbol estimation and linear decoding in the electrical domain. While realizing 100G optical transmission, a series of major technological changes have taken place in 100G optical module, including polarization multiplexing phase modulation technology, digital coherent receiving technology, the third generation super error correction coding technology, etc., so as to meet the needs of users to keep pace with the times.

Connection scheme of 100g optical module

100G is composed of four 25G channels, and the 100G QSFP28 SR4 optical module is directly connected to transmit data by using MPO/MTP backbone jumper.

Application field of 100g QSFP28 SR4 optical module

Easy sky optical communication ETU-LINK 100G QSFP28 SR4 optical module, mainly applies data center high-speed optical module. IEEE 802.3bm 100GBASE SR4 and 40GBASE SR4 and Infiniband FDR/EDR fourteen times speed / enhancement times speed. High-efficiency optical modules can be provided to customers through proprietary design.

With the wide application of 100G network technology, 100G QSFP28 optical module and 40G QSFP+ optical module are becoming more and more common and cost-effective.
