Arista SFP-10G-MRA-T | 10G SFP+ Transceiver, Multi-Rate Copper RJ-45, 30m

Q: What speeds does the SFP-10G-MRA-T support?
A: The SFP-10G-MRA-T is a rate-adapting transceiver supporting 100M, 1G, 2.5G, 5G, and 10G BASE-T. It automatically negotiates the appropriate speed with the connected copper device, allowing a single transceiver to handle multiple data rates without reconfiguration.

Q: What cable types are required for different speeds?
A: For 10G operation, Cat6a or Cat7 cable is required with a maximum reach of 30 meters. For 1G, 2.5G, and 5G speeds, Cat5e, Cat6, Cat6a, or Cat7 can be used with distances up to 100 meters. Lower speeds (100M) also support up to 100m over Cat5e or better.

Q: Does this transceiver replace the need for external media converters?
A: Yes. The SFP-10G-MRA-T eliminates the need for external media converters when connecting Arista switches to legacy 1G or 100M copper endpoints. It plugs into any supported 10G SFP+ port and handles speed conversion internally through automatic rate adaptation.

Q: Is the SFP-10G-MRA-T compatible with all Arista switches?
A: The transceiver is compatible with Arista switches running EOS 4.28.1F or later. Refer to the Arista Transceiver and Cable Guide (Table 11.1) for specific platform compatibility and deployment requirements before installation.

Q: What are typical use cases for this transceiver?
A: Common applications include enterprise LAN deployments with mixed-speed endpoints, data center intra-rack and inter-rack connections, connecting Wi-Fi access points or IP phones, and server-to-switch connectivity where copper cabling is preferred over fiber. It is particularly useful in environments transitioning from 1G to 10G infrastructure.
