Cisco QDD-400G-ER4-S Compatible 400GBASE-ER4 QSFP-DD PAM4 LWDM4 1310nm 40km SMF Duplex LC DOM/DDM Optical Transceiver ModuleDescription NADDOD Cisco QDD 400G ER4 S Compatible 400G QSFP DD ER4 is a 400Gb s QSFP DD optical transceiver module designed for long haul transmission. It converts eight 50Gb s PAM4 electrical inputs into four LAN WDM optical channels, multiplexed into a single 400Gb s optical signal. On the receive side, the 400Gb s signal is demultiplexed and converted back into eight 50Gb s PAM4 electrical outputs. Operating at LAN WDM wavelengths of 1295. 56,

It features Type B polarity and a magenta LSZH (OFNR) jacket for maximum protection and signal integrity over long reaches

Built with Trunk polarity and a magenta 2

0mm cable assembly ensures signal integrity with an insertion loss of ≤ 0
