Description

The Arista AOC-S-S-25G-3M is a 25GbE SFP28-to-SFP28 Active Optical Cable (AOC) delivering 25 Gb/s over 3 metres of multi-mode fibre at 850nm — ideal for high-density data centre top-of-rack and inter-switch interconnects. Unlike passive copper DACs, the embedded active optical transceivers provide superior signal integrity, eliminate electromagnetic interference, and reduce cable bulk, making them the preferred choice for high-speed, short-reach connectivity in modern data centre fabrics.

Designed and programmed specifically for Arista Networks platforms, this plug-and-play cable requires no field termination and draws less than 1W per end — ensuring energy-efficient operation across large-scale deployments. Compatible with Arista switches supporting 25GBase-AOC, it integrates seamlessly into spine-leaf architectures and high-performance computing environments. Order direct from iptrading.com.au — Australian-owned and operated since 2001.

Features

- Hot-pluggable SFP28 form factor — tool-free, snap-in installation
- Active optical design with embedded transceivers for superior signal integrity
- Eliminates electromagnetic interference (EMI) — ideal for dense cable environments
- Lightweight construction significantly reduces cable bulk versus copper DACs
- Pre-terminated plug-and-play — no field splicing or termination required
- Designed and programmed specifically for Arista Networks switching platforms
- Low power consumption (< 1W) supports energy-efficient, high-density deployments
- Part of the AOC-S-S-25G-xM series, available in lengths from 3m to 30m

FAQs

Q: What switches is the AOC-S-S-25G-3M compatible with?
A: This cable is designed and programmed specifically for Arista Networks platforms supporting 25GBase-AOC, including the 7050X3, 7060X, 7260X, and other Arista switches with SFP28 ports. Always verify compatibility with your specific switch model via Arista's transceiver compatibility matrix.

Q: What is the difference between an AOC and a DAC cable?
A: A Direct Attach Copper (DAC) cable uses copper conductors and passive signalling, limiting reach to around 5 metres and making it susceptible to EMI in dense environments. An Active Optical Cable (AOC) uses embedded optical transceivers and fibre, offering cleaner signal integrity, reduced cable weight, and support for longer distances up to 30m — at the cost of slightly higher unit price.

Q: Can I use this cable in a third-party switch, such as Cisco or Juniper?
A: The AOC-S-S-25G-3M is programmed specifically for Arista platforms. While the physical SFP28 connector is standard, many vendors enforce transceiver compatibility checks. Using this cable in non-Arista equipment may result in it being unrecognised or unsupported. For multi-vendor environments, consider a third-party branded AOC or contact IP Trading for guidance.

Q: What fibre type is required for the AOC-S-S-25G-3M?
A: This is a fully self-contained Active Optical Cable — the fibre is built into the cable assembly. No separate fibre patch cord or transceiver is needed. Both ends terminate in SFP28 connectors that plug directly into your switches.

Q: Is the AOC-S-S-25G-3M available in other lengths?
A: Yes. Arista offers the AOC-S-S-25G series in multiple lengths including 3m, 5m, 7m, 10m, 15m, 20m, and 30m. Contact IP Trading to check stock availability for other lengths in the series.

Q: Can I purchase the Arista AOC-S-S-25G-3M in Australia from IP Trading?
A: Yes. iptrading.com.au is an Australian-owned and operated IT hardware reseller based in Australia since 2001. We stock Arista optics and cables and can assist with volume orders, compatibility queries, and local pre-sales support. Order online or contact our team directly.
