Description

The Arista AOC-Q-Q-40G-3M is a QSFP+ to QSFP+ 40GbE Active Optical Cable (AOC) delivering 40Gbps aggregate bandwidth over 3 metres of multimode fibre. Designed for data centre intra-rack and inter-rack interconnects, this pre-terminated, plug-and-play cable assembly eliminates the need for separate transceivers and patch cords. Its 850 nm VCSEL array transmitter delivers reliable signal integrity with lower EMI than copper DAC alternatives, making it ideal for high-density, high-performance computing deployments.

Compliant with IEEE 802.3ba (40GBASE-SR4) and the SFF-8436 QSFP+ standard, this AOC is hot-swappable for zero-downtime deployment and replacement. It is fully supported on Arista 40G Ethernet switches, routers, and servers running EOS version 4.13.0 or later. The lightweight, flexible fibre construction reduces port stress and simplifies cable management in congested rack environments. Available now at iptrading.com.au — competitive prices and local support.

FAQs

Q: What devices is the AOC-Q-Q-40G-3M compatible with?
A: The AOC-Q-Q-40G-3M is supported on Arista 40G Ethernet switches, routers, and servers running Arista EOS version 4.13.0 or later. It uses the standard SFF-8436 QSFP+ connector, making it broadly compatible with any equipment featuring a QSFP+ port rated for 40GBASE-AOC.

Q: What is the difference between an AOC and a DAC cable?
A: An Active Optical Cable (AOC) uses multimode fibre and embedded optical transceivers to transmit data as light signals, offering lower EMI, lighter weight, and longer reach than copper Direct Attach Cables (DAC). AOCs like the AOC-Q-Q-40G-3M are ideal for environments where EMI interference or cable bulk is a concern.

Q: Can this cable be used for inter-rack connections in a data centre?
A: Yes. At 3 metres, the AOC-Q-Q-40G-3M is suited to both intra-rack and short inter-rack high-speed interconnects. The flexible fibre construction simplifies routing through cable management arms and overhead trays without stressing QSFP+ ports.

Q: Is the AOC-Q-Q-40G-3M hot-swappable?
A: Yes. The QSFP+ form factor is hot-swappable, allowing the cable to be inserted or removed without powering down the connected equipment, minimising downtime during installation or replacement.

Q: Can I purchase the Arista AOC-Q-Q-40G-3M in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) stocks Arista transceivers and cables in Australia, offering competitive pricing and local support. Contact the team for volume pricing, lead times, and compatibility advice.

Q: What fibre type is required to use this cable?
A: The AOC-Q-Q-40G-3M is a pre-terminated active optical cable — the fibre is built into the assembly. No external patch cable or transceiver is required. The embedded multimode fibre operates at 850 nm, fully compliant with IEEE 802.3ba (40GBASE-SR4).
