Description
This product is a 100Gb/s transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE P802.3ba standard.
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 DFB transmitters and high-sensitivity PIN receivers provide superior performance for 100-Gigabit Ethernet applications up to 10km links and compliant to optical interface with IEEE 802.3ba Clause 88 100GBASE-LR4 requirements.
The product has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
