Description

The Arista SFP-25G-MR-LR is a dual-rate 10/25GBASE-MR-LR SFP28 optical transceiver designed for flexible, long-reach connectivity in enterprise and data centre environments. Operating at 1310nm over duplex single-mode fibre (SMF) with an LC duplex connector, it delivers transmission distances of up to 10km at either 10G or 25G — making it an ideal choice for organisations migrating from 10G to 25G infrastructure without replacing existing fibre runs.

Compliant with SFP28 MSA, IEEE 802.3by, and IEEE 802.3cc standards, this transceiver supports broad interoperability across Arista 25G SFP platforms and 10G SFP+ interfaces. Digital Diagnostics Monitoring (DDM/DOM) provides real-time visibility of optical power, temperature, bias current, and supply voltage for proactive network management. Its hot-swappable design ensures non-disruptive installation and replacement. Order now at iptrading.com.au — trusted by Australian IT professionals.

FAQs

Q: What speeds does the Arista SFP-25G-MR-LR support?
A: The SFP-25G-MR-LR is a dual-rate transceiver that operates at both 10G (10.31 Gbps) and 25G (25.78 Gbps), giving network teams the flexibility to use the same module across mixed-speed environments or during a phased 25G migration.

Q: What fibre type and maximum distance does this transceiver support?
A: This transceiver uses duplex single-mode fibre (SMF) with an LC duplex connector, transmitting at 1310nm for distances of up to 10km — suitable for long-reach data centre interconnects and campus backbone deployments.

Q: Is the SFP-25G-MR-LR compatible with non-Arista switches?
A: The SFP-25G-MR-LR is SFP28 MSA compliant and adheres to IEEE 802.3by and IEEE 802.3cc standards, which provides a strong basis for interoperability with third-party 25G SFP28 interfaces. However, compatibility with specific non-Arista platforms should be verified before deployment.

Q: Does this transceiver support Digital Diagnostics Monitoring?
A: Yes. The SFP-25G-MR-LR supports DDM/DOM (Digital Diagnostics Monitoring), enabling real-time visibility of key optical and electrical parameters including transmit/receive power, temperature, bias current, and supply voltage directly from the switch management interface.

Q: Can I purchase the Arista SFP-25G-MR-LR in Australia?
A: Yes. The Arista SFP-25G-MR-LR is available from iptrading.com.au, a trusted B2B IT hardware reseller serving Australian IT professionals and enterprise networks. Order online or contact the team for volume pricing and availability.

Q: Is this transceiver suitable for 100G breakout configurations?
A: Yes. The SFP-25G-MR-LR supports breakout applications, making it suitable for use in 100G to 4x25G or 4x10G breakout deployments — a common architecture in modern data centre leaf-spine and aggregation layers.
