General Description
Hi-Optel’s 200G QSFP-DD transceiver module is designed for use in 200G Ethernet interfaces over single mode fiber. It is compliant with both the QSFP-DD MSA and 200GBASE-LR4 specification. 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 DML TOSA transmitters and PIN-PD receivers provide superior performance for 200G Ethernet applications up to 10km links with FEC. Digital diagnostics functions are available via the I2C interface, as specified by QSFP-DD MSA. This product is intended to support data center applications.
