Description

This Arista 25G SFP28 active optical cable is a pre-terminated 30 metre link with SFP28 connectors at both ends, running over 850nm multimode fibre. It is part of the Arista Optics Modules and Cables portfolio and is built for short-reach, high-density 25GbE connections between Arista switches and servers or NICs.

The 30m length is the longest in the 25G AOC range, which spans 3, 5, 7, 10, 15, 20, 25 and 30 metres. It suits top-of-rack and end-of-row runs where 25GBASE-CR twinax copper, limited to 1 to 5 m, cannot reach and where lighter cabling is preferred. As a pre-terminated active optical cable, it removes the need for separate optics or fibre patching. It is hot swappable, so it can be fitted or replaced without powering down the host, and it draws its power from the host port. Operating case temperature is 0 to 70 C.

It fits SFP28 (25GbE) ports on Arista switches and on servers or NICs with SFP28 ports. Check Arista's transceiver compatibility matrix for the exact switch platforms and EOS versions.

FAQs

Q: How long a run does this cable support?
A: This cable is a fixed 30 metre length. The 25G AOC range is also made in 3, 5, 7, 10, 15, 20 and 25 metre lengths for shorter runs.

Q: What ports does it connect to?
A: It has SFP28 connectors at both ends and fits SFP28 (25GbE) ports on Arista switches and on servers or NICs with SFP28 ports.

Q: Do I need separate optics or fibre patching?
A: No. It is a pre-terminated active optical cable with the optics built into each connector, so it plugs straight into two SFP28 ports.

Q: When should I choose this over a 25G twinax copper cable?
A: Choose it when the link is longer than the 1 to 5 m reach of 25GBASE-CR twinax copper, or when lighter fibre cabling is preferred for dense racks.

Q: Can it be installed while the switch is powered on?
A: Yes. The cable is hot swappable, so it can be inserted or removed without powering down the host.
