Description

Ultra-short 400G active optical cable with integrated QSFP-DD transceivers for within-rack or adjacent device links. Provides simple, low-latency 400GbE connectivity where a compact 1m length reduces slack and improves airflow. Ideal for top-of-rack switch to server/NIC connections.

Features

- Compact 1m length minimizes slack and improves airflow
- Integrated QSFP-DD optics for plug-and-play deployment
- Low-latency, low-power 400GbE interconnect
- Flexible jacket eases tight cable routing
- Standards-based for broad interoperability
- Reliable performance for dense top-of-rack environments

FAQs

Q: Is 1m long enough for within-rack connections?
A: Yes, 1m is ideal for devices mounted in close proximity within the same rack.

Q: Why choose a 1m AOC over a DAC?
A: AOCs offer better flexibility and potentially lower electromagnetic interference versus copper DACs.

Q: Does this support 400GbE on all QSFP-DD platforms?
A: It is MSA-compliant and supports standard 400GbE QSFP-DD ports on switches and NICs.

Q: Are the connectors removable?
A: No, the QSFP-DD ends are integrated and not user-removable.

Q: Can it be used for breakout to 8x50G?
A: This is a straight 400G-to-400G AOC; for breakout you would need a dedicated breakout AOC model.
