400G QSFP-DD Optical Transceiver Series

EN-QDD-FR4

AT A GLANCE
E.C.I. NETWORKS’s QSFP-DD or QSFP56-DD transceiver module is designed for use in 200/400 Gigabit
Ethernet links up 10km single mode fiber. QSFP-DD ports is mechanically and electrically compatible withQSFP28 and QSFP+. The module is hot pluggable when mated to a compliant 76-pin connector thatdelivers a supply voltage of 3.3 V.
EN-QDD-FR4 is a 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module
designed for 2km optical communication applications. The module converts 8 channels of 50Gb/s (PAM4)electrical input data to 4 channels of CWDM optical signals and multiplexes them into a single channel for400Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a400Gb/s optical input into 4 channels of CWDM optical signals and converts them to 8 channels of 50Gb/s(PAM4) electrical output data.

EN-QDD-FR4
EN-QDD-FR4 Direct Connectivity
The 400G-FR4/LR4 modules use duplex LC fiberconnectors – the same connectors that are used on
existing 100G and 40G QSFPs that use duplex SMF (e.g.
100G-CWDM4, 40G-LR4 etc).
