Arista compatible SFP-10G-RA-1G-SX Description
EdgeOptic's SFP-10G-RA-1G-SX compatible is an Arista-coded version of the EdgeOptic 10G-SFP-300 multi-vendor multi-rate SFP+ transceiver, configured as a rate-adapting optic. SFP-10G-RA-1G-SX is Arista Networks' ordering code for a 10G-host-to-1G-media rate-adapting SFP+, where the host-side electrical interface runs at 10G XFI and the fiber-side optical interface runs at 1000BASE-SX. The optic carries Arista-recognized EEPROM identification so switch firmware registers the module under the standard transceiver-acceptance policy.
The host-side interface presents 10G XFI to the Arista switch port, while internal rate-adaptation circuitry drives the optical engine at the 1000BASE-SX 1.25 Gbps line rate per IEEE 802.3z. The fiber link runs at 1G, not at 10G; this is the critical distinction from a standard 10GBASE-SR SFP+. Fiber reach follows the 1000BASE-SX specification at 850 nm: up to 220 m on OM1, 550 m on OM2, with OM3 and OM4 reach per the 1000BASE-SX profile rather than the 10GBASE-SR profile. DDM telemetry per SFF-8472 exposes the standard transceiver health parameters: temperature, supply voltage, TX bias, TX power, and RX power. Form factor is SFP+ (SFF-8431 MSA) at the standard commercial operating range.
The rate-adapting profile suits deployments where an Arista 10G switch port needs to connect to legacy 1G 1000BASE-SX fiber infrastructure without swapping the switch-side optic to a 1G SFP. The host-side rate adaptation absorbs the 10G-to-1G signaling difference inside the module, so the switch port remains a 10G XFI cage from the host perspective. Verify the SFP-10G-RA-1G-SX ordering code against the current Arista transceiver compatibility documentation for the target switch generation, since rate-adapting optic support varies across Arista 7050, 7060, and 7280 platforms by EOS release. SFP+ optics do not auto-negotiate at the optical layer; the rate-adapting function is a host-side electrical bridge, not an optical negotiation.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For Arista 10G-to-1G fiber migration planning, mixed-rate switch deployment, or bulk SFP-10G-RA-1G-SX inventory, contact our sales team.
Frequently Asked Questions
What fiber reach does the SFP-10G-RA-1G-SX support, 10GBASE-SR reach or 1000BASE-SX reach?
1000BASE-SX reach. The fiber link runs at the 1.25 Gbps 1000BASE-SX line rate per IEEE 802.3z, so the reach envelope follows 1000BASE-SX (typically up to 220 m on OM1, 550 m on OM2) and not the 10GBASE-SR 300 m OM3 / 400 m OM4 envelope. On OM3 and OM4 fiber, reach follows the 1000BASE-SX specification per IEEE 802.3z Table 38-6 rather than the 10GBASE-SR envelope; plan cable-length budgets against 1000BASE-SX specifications for the installed fiber grade. The 10G XFI rate exists only on the host-side electrical interface between the switch ASIC and the module; the optical signal on the fiber is 1G.
