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 is designed for use in 200Gb/s InfiniBand HDR systems or 200G Ethernet netwoking

SR4 multimode parallel transceiver using a single

It is optimized to supercharge hyperscale AI computing workloads

This configuration enables efficient 400G-to-800G interconnection

It features a 4-channel parallel architecture with 100G-PAM4 modulation per lane

NADDOD O2Q56-400G-CUAH is a passive Direct Attach Copper (DAC) cable with an OSFP-based twin-port 2x 200Gb/s connector to two 200Gb/s QSFP56s

which is a 4-channel (CWDM4) QSFP28 transceiver designed for use in 100 Gigabit Ethernet (GbE) links over up to 2km of single mode fibre

The "active" term refers to the passive copper cable with an equalizer integrated circuit to extend the length to 4 and 5-meters while maintaining very low-latency and very low-power

NVIDIA/Mellanox MMS4X00-NM-T Compatible OSFP-800G-2xDR4 optical transceiver is a high-speed

NADDOD O4O112-800G-AC5H is an 800Gb/s twin-port OSFP (Octal Small Form-factor Pluggable) Finned Top to 4x200Gb/s OSFP Flat Top Active Copper Cable (ACC) dual breakout (aka splitter) cable

It uses a single 4-channel MPO-12/APC optical connector and adopts 100G-PAM4 modulation per lane

with ports spanning from 1 to 200GbE and port density that enables full rack connectivity to any server at any speed
