Description

The Arista SFP-10G-RA-1G-SX is a rate adapting SFP+ transceiver designed to bridge 10G switch ports with existing 1G SX fibre infrastructure — eliminating the need to replace legacy cabling or switches prematurely. Operating with a 10G XFI host-side interface, it automatically adapts down to 1000BASE-SX (1.25 Gbps) on the media side, with internal Clause 37 auto-negotiation ensuring seamless link establishment. Transmitting at 850nm over multi-mode fibre via duplex LC connector, it supports reach up to 550m on OM2 (500 MHz·km) MMF — ideal for enterprise campus and data centre migration scenarios.

Digital Optical Monitoring (DOM) enables real-time diagnostic visibility into optical power, temperature, and voltage, supporting proactive network management. The hot-swappable SFP+ form factor and MSA compliance make it straightforward to deploy, and it integrates natively with Arista EOS and CloudVision for centralised management. Compatible with specific Arista platforms — consult the Arista Transceiver and Cable Guide for supported hardware. Need it fast? iptrading.com.au delivers across Australia — shop now.

FAQs

Q: What problem does the SFP-10G-RA-1G-SX solve?
A: This transceiver allows a 10G SFP+ switch port to connect to a 1G (1000BASE-SX) fibre link. It rate-adapts from the 10G host interface down to 1G on the media side, enabling organisations to leverage existing 1G MMF infrastructure without replacing switches or cabling when upgrading to 10G-capable hardware.

Q: What type of fibre cable is required?
A: The SFP-10G-RA-1G-SX requires multi-mode fibre (MMF) with a duplex LC connector. It operates at 850nm and supports link distances up to 550m over OM2 (500 MHz·km) fibre, or shorter distances over lower-grade MMF.

Q: Is auto-negotiation supported?
A: Yes. The transceiver includes internal Clause 37 auto-negotiation support on the media interface, ensuring reliable and automatic link establishment with connected 1G SX equipment without requiring manual speed configuration.

Q: Which Arista switches support this transceiver?
A: This transceiver is supported on specific Arista platforms. Refer to the Arista Transceiver and Cable Guide (available on arista.com) for the full list of compatible switch models and EOS software versions.

Q: Does it support Digital Optical Monitoring (DOM)?
A: Yes. DOM is supported, providing real-time diagnostic data including optical transmit/receive power, temperature, supply voltage, and bias current — accessible via Arista EOS CLI or CloudVision for proactive fault detection.

Q: Can I purchase this transceiver in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) stocks Arista optics and delivers across Australia. Contact our team for pricing, availability, and volume purchasing enquiries for the SFP-10G-RA-1G-SX.
