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

Q: What speeds does the SFP-10G-MRA-T support?
A: The SFP-10G-MRA-T supports 10G, 1G, and 100M BASE-T over a copper RJ-45 interface. It is rate-adapting, meaning a single transceiver can automatically negotiate and communicate with connected devices at any of these three speeds depending on the endpoint capability.

Q: What cable type is required for 10G performance?
A: For 10G speeds, Cat6a or Cat7 cable is required with a maximum reach of 30 metres. For 1G or 100M operation, Cat5e or Cat6 cable is sufficient and supports distances up to 100 metres.

Q: Do I need a media converter to connect legacy 1G or 100M devices to a 10G Arista switch?
A: No. The SFP-10G-MRA-T eliminates the need for an external media converter by handling the speed conversion internally. It plugs into any 10G SFP+ port on a supported Arista switch and negotiates the appropriate speed with the connected copper device automatically.

Q: What Arista platforms support the SFP-10G-MRA-T?
A: The SFP-10G-MRA-T is supported on specific Arista platforms running EOS 4.28.1 or later. Refer to the Arista Transceiver and Cable Guide Table 11.1 for a complete list of compatible platforms and any restrictions before deployment.

Q: Is this transceiver suitable for data centre or enterprise environments?
A: Yes, the SFP-10G-MRA-T is ideal for enterprise networks and data centres with mixed-speed copper cabling where infrastructure consolidation is required. It enables direct copper connections to legacy or mixed-speed endpoints without additional hardware, reducing complexity and cost.
