Description

The Arista AOC-S-S-25G-20M is a 25GbE SFP28 to SFP28 Active Optical Cable (AOC) engineered for high-density, low-latency direct-attach fibre connectivity in modern data centres. Spanning 20 metres over multimode fibre with 850nm VCSEL technology, it delivers a cost-effective, low-power alternative to discrete optical transceivers paired with patch cables — ideal for intra-rack and adjacent rack-to-rack 25Gbps interconnects. Full plug-and-play interoperability with Arista's 25G switching platforms ensures seamless deployment with no additional configuration required.

Compliant with 25GBASE-AOC, SFF-8402, SFF-8431, and SFF-8472 SFP28 MSA standards, this AOC supports 25 Gigabit Ethernet, InfiniBand, and Fibre Channel applications. Digital Optical Monitoring (DOM) provides real-time visibility into temperature, voltage, and optical levels, simplifying diagnostics in production environments. RoHS compliant and drawing less than 1W typical power, it suits high-density spine-leaf and top-of-rack deployments.

FAQs

Q: What switch platforms is the AOC-S-S-25G-20M compatible with?
A: The AOC-S-S-25G-20M is fully qualified for plug-and-play interoperability with Arista's broad range of 25G SFP28 data centre switching platforms, including the 7050X, 7060X, and 7280R series. It is also compliant with the SFP28 MSA standard, making it broadly compatible with third-party 25G SFP28 ports.

Q: What fibre type does this AOC require?
A: This cable uses multimode fibre (MMF) with an 850nm VCSEL light source. It is designed as a fixed-length direct-attach assembly — no separate patch cable or transceiver is required. Simply plug it into any compatible SFP28 port on both ends.

Q: How does an Active Optical Cable differ from a DAC or discrete transceiver pair?
A: A DAC (Direct Attach Copper) cable is limited to shorter distances (typically up to 5m) and is heavier. Discrete transceivers with patch cables offer maximum flexibility but at higher cost and power. An AOC like the AOC-S-S-25G-20M bridges the gap — offering fibre's low EMI and lighter weight at a longer reach (up to 20m in this case) while consuming less than 1W, making it ideal for cross-rack data centre links.

Q: Does this cable support Digital Optical Monitoring (DOM)?
A: Yes. The AOC-S-S-25G-20M supports DOM, providing real-time diagnostics including temperature, supply voltage, and optical power levels. This simplifies troubleshooting and ongoing monitoring in production data centre environments.

Q: Is Forward Error Correction (FEC) enabled on this cable?
A: FEC is disabled by default on all Arista 25G AOC cables, including the AOC-S-S-25G-20M. Ensure your switch port FEC settings align accordingly. Consult Arista's compatibility documentation or the IP Trading team if you require specific FEC configuration guidance.

Q: Can I purchase the AOC-S-S-25G-20M in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller stocking Arista networking products including AOC cables. The team can assist with bulk orders, compatibility queries, and delivery across Australia. Visit iptrading.com.au or contact the team directly for pricing and availability.
