Description

The Arista SFP-25G-MR-SR is a dual rate 10/25GBASE-SR SFP28 optical transceiver designed for multimode fibre deployments in data centre and enterprise environments. Operating at either 10G or 25G in a single module, it delivers up to 300m/400m over OM3/OM4 MMF at 10G and up to 70m/100m over OM3/OM4 MMF at 25G. Its ability to optically interoperate with standard 10G-SR transceivers when running at 10G makes it an ideal solution for phased network upgrades from 10G to 25G infrastructure.

Built around an 850nm VCSEL transmitter with LC duplex connectivity, the SFP-25G-MR-SR supports Digital Optical Monitoring (DOM) for real-time diagnostics and is fully RoHS compliant. It conforms to SFP28 MSA, IEEE 802.3by, and SFF standards for broad platform compatibility. Get it now at iptrading.com.au — authentic hardware, reliable service.

Features

- Dual rate 10G/25G operation in a single SFP28 module — simplifies inventory and sparing
- Optically interoperates with standard 10G-SR SFPs at 10G for seamless migration
- Extended 10G reach: up to 400m over OM4 MMF — ideal for campus and data centre runs
- Digital Optical Monitoring (DOM) for real-time transceiver diagnostics and health visibility
- Hot-swappable SFP28 form factor for zero-downtime installation and replacement
- MSA-compliant (SFP28 MSA, IEEE 802.3by) for broad multi-vendor interoperability
- 850nm VCSEL transmitter for reliable, cost-effective multimode fibre performance
- RoHS compliant and Class 1 laser safety certified

FAQs

Q: What fibre distances does the Arista SFP-25G-MR-SR support?
A: At 25G, it reaches up to 70m over OM3 and 100m over OM4 multimode fibre. At 10G, it extends to 300m over OM3 and 400m over OM4, making it suitable for both short and medium intra-data-centre runs.

Q: Can the SFP-25G-MR-SR interoperate with existing 10G-SR transceivers?
A: Yes. When operating at 10G, the SFP-25G-MR-SR optically interoperates with standard 10G-SR SFP transceivers. This enables seamless phased upgrades from 10G to 25G without replacing the entire fibre infrastructure simultaneously.

Q: What Arista switches and platforms is this transceiver compatible with?
A: The SFP-25G-MR-SR is designed for use with Arista 25G-capable switches and platforms such as the 7050X, 7060X, and 7280R series. It is also MSA-compliant, providing broad interoperability across compatible third-party equipment.

Q: Does this transceiver support Digital Optical Monitoring (DOM)?
A: Yes, DOM is supported, allowing real-time monitoring of key transceiver parameters including optical power levels, temperature, and supply voltage. This simplifies fault diagnosis and proactive network management.

Q: Can I purchase the Arista SFP-25G-MR-SR in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller stocking genuine Arista optics including the SFP-25G-MR-SR. Contact us for pricing, availability, and volume enquiries.

Q: What type of connector and fibre cable does this transceiver require?
A: The SFP-25G-MR-SR uses an LC duplex connector and requires OM3 or OM4 multimode fibre patch cables. OM4 is recommended for maximum reach at both 10G and 25G speeds.
