Description

This Arista 400G active optical cable is a pre-terminated assembly with a QSFP-DD connector at each end, built for short-reach 400GbE links inside a data centre. It suits leaf-spine uplinks, switch-to-switch connections and AI and HPC cluster links where a rack or row-length run of up to 30 m is needed.

The cable is the 400GBASE-AOC type, running over 850 nm multi-mode fibre with the transceivers permanently fitted to the cable. This SKU is the QSFP-DD to QSFP-DD, 30 m version. It draws a maximum of 12 W from the host switch port, so no separate power supply is needed, and it is hot-swappable for simple servicing.

It fits 400G QSFP-DD ports on Arista switches. Breakout variants such as QSFP-DD to 4x QSFP28 are separate SKUs, so choose this one only for straight QSFP-DD to QSFP-DD links.

Enquire with XS Network Tech for new or used pricing and availability.
