100G QSFP28 ZR4 光模块

Description
This product is a 100Gbps transceiver module designed for optical communication applications compliant to 100GBASE-ZR4. The module converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of LAN WDM optical signals and then converts them to 4 output channels of electrical data.
The central wavelengths of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm as members of the LAN WDM wavelength grid defined in IEEE 802.3ba. The high performance cooled LAN WDM EML transmitters and high sensitivity PIN+SOA receivers provide superior performance for 100Gigabit Ethernet applications up to 80km links.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
