400G QSFP-DD DAC
400G QSFP-DD Passive Direct Attach Copper Twinax Cable 0.5m to 3m
Description
400G QSFP-DD Direct Attach Passive Copper Cable
QSFP-DD uses PAM4 signals for transmission which doubles the data transfer rate. Arkoptics 400G QSFP-DD passive copper cable assembly features eight differential copper pairs, providing four data transmission channels, each channel up to 56Gbps (PAM4). It meets 400G Ethernet and InfiniBand Enhanced Data Rate(EDR) requirements. The QSFP-DD-to-QSFP-DD copper direct attach solution is suitable for very short links and offers a cost-effective method to establish a 400 Gigabit link between QSFP-400G ports of switches and routers within racks and across adjacent racks.
Arkoptics currently offers 400G QSFP-DD DAC in lengths of 0.5m, 1m, 1.5m, 2m, 2.5m and 3m, with a variety of wire gauges from 28AWG to 32AWG. It is compliant with Hot Pluggable QSFP-DD MSA, IEEE 802.3bj, IEEE 802.3cd Standard.
