Arista SFP-25G-MR-LR-Arista | 10/25G SFP28 Transceiver, Single-Mode, 10km, 1310nm

Q: What speeds does the SFP-25G-MR-LR support?
A: This transceiver is dual-rate and supports both 10G Ethernet (10.31 Gbps) and 25G Ethernet (25.78 Gbps), providing deployment flexibility for mixed-speed environments and future network upgrades.

Q: Can this module interoperate with legacy 10G optics?
A: Yes, the SFP-25G-MR-LR is designed to interoperate with 10GBASE-LR transceivers when operated at 10G speeds. However, attenuation may be required for shorter link distances to ensure the 10G receiver is not overloaded.

Q: What platforms support the SFP-25G-MR-LR transceiver?
A: This transceiver is compatible with Arista switches that have SFP28 or SFP+ ports supporting dual-rate operation. It can be used in various Arista platforms including data center switches and enterprise campus switches with 25G SFP capabilities.

Q: Does this transceiver support Digital Optical Monitoring?
A: Yes, the SFP-25G-MR-LR includes DDM/DOM functionality, enabling real-time monitoring of critical parameters including optical output power, received optical power, temperature, bias current, and supply voltage.

Q: What is the typical application for this transceiver?
A: Common deployments include data center interconnects, ISP fiber-to-the-home aggregation and backbone networks, mobile operator core networks and backhaul, and enterprise campus backbone links requiring reliable 10km single-mode fiber connectivity at 10G or 25G speeds.
