Overview
The 3HE10552AA-FL is a 103 Gbps transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE P802.3ba standard. The module converts 4 input channels of 25 Gbps electrical data to 4 optical CWDM channels and then multiplexes them into a single channel for 103 Gbps optical transmission. Reversely on the receiver side, the module de-multiplexes a 103 Gbps optical input into 4 channels of CWDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 LAN WDM channels are 1270, 1290, 1310 and 1330 nm as members of the CWDM wavelength grid. The high performance cooled DML DFB transmitters and high sensitivity PIN receivers provide superior performance for 100G applications up to 2km links. The product is designed with form factor, optical/electrical connection and digital diagnostic interface per the QSFP+ Multi- Source Agreement (MSA).
