GF-6800-400GQDD – 400G QSFP-DD DWDM Muxponder
The GF-6800-400GQDD is a compact, high-capacity 400G DWDM muxponder designed for Data Center Interconnect (DCI), metro and optical transport networks.
The module provides 4 × 100GE QSFP28 client-side interfaces and a QSFP-DD coherent DWDM line-side interface supporting flexible transmission rates from 100G to 400G. The solution supports multiple optical transmission technologies including FlexO, ZR, ZR+, DR and LR.
Integrated diagnostics, OSNR monitoring, real-time BER monitoring and comprehensive fault-management functions provide reliable operation in high-capacity DWDM networks.
