Description

This Arista dual-rate SFP28 transceiver runs at either 25GbE or 10GbE over duplex 850nm multimode fibre with LC connectors. It is built for data centre and campus top-of-rack or server-to-switch links, and suits 10G-to-25G migrations because the same optic works at 10G on older ports and at 25G on newer ones.

At 25G it reaches 70m over OM3 or 100m over OM4. At 10G the reach extends to 300m over OM3 or 400m over OM4. It uses 50.0 um core multimode fibre, draws a maximum of 1.5 W from the host port, and operates over a case temperature range of 0 to 70 C. The module is hot swappable and uses the compact SFP form factor.

It fits SFP28 and SFP+ ports on Arista switches that support 25G/10G SFP optics. When operated at 10G it interoperates with standard 10G-SR optics, which makes mixed-speed links straightforward.

FAQs

Q: Does this transceiver need a licence or subscription?
A: No. It is a passive optical module and runs on the host port without any licence.

Q: What power does it draw?
A: Maximum power consumption is 1.5 W, supplied by the host switch or NIC port.

Q: Can it link to a 10G-SR optic?
A: Yes. When operated at 10G it interoperates with standard 10G-SR optics over multimode fibre.

Q: Which ports and fibre does it work with?
A: It fits SFP28 and SFP+ ports on Arista switches that support 25G/10G SFP optics, using duplex LC multimode fibre (OM3 or OM4). Check the Arista transceiver compatibility matrix for your specific platform and EOS version.

Q: How far can it reach?
A: At 25G it reaches 70m on OM3 or 100m on OM4. At 10G it reaches 300m on OM3 or 400m on OM4.
