Description

This Arista 10/25G dual-rate SFP28 transceiver is built for duplex single-mode fibre links with LC connectors. It operates at 1310nm and reaches up to 10 km, making it suited to data centre top-of-rack and leaf uplinks as well as campus and inter-building runs. Because it runs at either 25GbE or 10GbE, it also suits teams migrating from 10G to 25G without changing optics.

The module is a 25GBASE-MR-LR optic in the standard SFP form factor. Transmit power is -7 to 2.0 dBm and receive power is -13.3 to 2.0 dBm, with a maximum power draw of 1.5 W taken from the host switch port, so no separate power supply is needed. When run at 10G it can link to 10GBASE-LR optics, although attenuation may be required to keep the optical input power within the limits of the 10G module. Proper attenuation is also needed on shorter links to protect the receiver.

It fits SFP and SFP28 ports on supported Arista platforms. Check Arista's Transceiver and Cable Guide for the supported platform and EOS list before deployment.

FAQs

Q: Can this module link to a 10G LR optic?
A: Yes. When run at 10G it interoperates with 10GBASE-LR optics. Attenuation may be required to keep the optical input power to the 10G module within allowable limits.

Q: What fibre does it need?
A: It uses duplex single-mode fibre (G.652) with LC connectors and reaches up to 10 km at 1310nm.

Q: Does it need external power?
A: No. It draws a maximum of 1.5 W from the host switch port and needs no separate power supply.

Q: Do I need attenuation on short links?
A: Yes. Proper optical attenuation is required on shorter links to protect the receiver from permanent damage.

Q: Which switches does it work with?
A: It fits SFP and SFP28 ports on supported Arista platforms. Check Arista's Transceiver and Cable Guide for the supported platform and EOS list.
