Arista SFP-10G-RA-1G-LX-Arista | Rate-Adapting Transceiver, 1G-LX to 10G, 10km SMF, LC

Q: What problem does the SFP-10G-RA-1G-LX solve?
A: It allows organisations to upgrade their switch infrastructure to 10G platforms without replacing existing 1000BASE-LX single-mode fibre cabling. The module internally rate-adapts between 10 Gbps on the host side and 1 Gbps on the media side, eliminating the need for external media converters.

Q: Is this transceiver compatible with all Arista switches?
A: No, the SFP-10G-RA-1G-LX is supported on specific Arista platforms with 10G SFP+ ports. Consult the official Arista Transceiver and Cable Guide to confirm compatibility with your specific switch model before deployment.

Q: Does this module require special configuration in Arista EOS?
A: No, the SFP-10G-RA-1G-LX is designed to be plug-and-play within supported Arista EOS environments. The rate adaptation and internal Clause 37 auto-negotiation are handled by the module itself, requiring no additional host-side configuration for basic operation.

Q: Can I use this transceiver with multi-mode fibre?
A: This module is designed for single-mode fibre operation over distances up to 10km. If using with FDDI-grade OM1 or OM2 multi-mode fibre, a mode conditioning patch cord is required at the transmitter. OM3 fibre does not require mode conditioning.

Q: What diagnostic capabilities does this transceiver support?
A: The module supports Digital Optical Monitoring (DOM), providing real-time diagnostics of operating parameters including temperature, voltage, transmit power, receive power, and laser bias current. This integrates with Arista EOS and CloudVision for full visibility and management.
