Arista QDD-400G-ER4 Compatible 400GBASE-ER4 QSFP-DD PAM4 LWDM4 1310nm 40km SMF Duplex LC DOM/DDM Optical Transceiver Module Breakout DAC The QSFP112-to-QSFP112 cable assembly integratesDescription NADDOD Arista QDD 400G ER4 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,
