Home / What are the features of a 40G DWDM optical module
T1-QSFP-40G-DWDM-C-XX's pluggable optical transceiver modules are designed for multiple 40GE links up to 80km distance over standard G. several kilometers, no EDFA and dispersion compensation modules (DCM) are required. 2Gbps per channel bandwidth Aggregate bandwidth of > 40Gbps Duplex LC connector Compliant. This solution has the larger link budget, can realize data transmission, 60 km, 80G without adding extra fiber, 40G optical signal is divided into 4 all the way road 10G optical signal, through OEO.
