StarTech.com AR-SFP-10G-LR-ST — Arista Compatible 10G LR SFP+
Arista coded10GBASE-LRLC single-modeUp to 10 km
The StarTech.com AR-SFP-10G-LR-ST is a 10 Gbit SFP+ transceiver coded to work as Arista’s SFP-10G-LR, the long-reach optic for Arista switches. It runs at 1310 nm over single-mode fibre with an LC duplex connector, reaches up to 10 km and supports digital diagnostics. It suits data centres and campuses on Arista gear that need 10G links between rooms, floors or buildings. In practice, single-mode optics are the choice when a link leaves the building or runs several hundred metres: the OS2 fibre used by carriers and campus backbones carries the signal for kilometres with little loss. Before you order, confirm the fibre is single-mode at both ends and note the length and the number of patch panels on the way.
Compatibility — check before buying:
It is coded for Arista SFP-10G-LR; StarTech.com lists Arista switches and routers without naming models, so tell us yours. It needs single-mode fibre and a 10GBASE-LR module at the far end — it will not link to an 850 nm SR optic or run over multimode fibre. For short multimode runs, Arista’s SR coding is a different StarTech.com part. Keep the dust cap on until you connect the fibre, and clean both connector ends before every mating — dirt is the most common cause of a link that will not come up. Not sure? Send us your switch model and the cable run and we check it before you order.
Best For

✓ Keeping a spare on the shelf
✓ Floor-to-floor risers on single-mode fibre
✓ Budget-conscious 10G rollouts
Key Features
Coded for Arista
Programmed to identify as Arista’s SFP-10G-LR, so Arista switches accept it as a 10 km single-mode optic.
Single-mode fibre, long reach
Built for single-mode (OS1/OS2) fibre, the type used between buildings, floors and sites. It will not run over the orange or aqua multimode fibre found in many racks — the fibre type has to match at both ends.
Monitoring you can read
Digital diagnostics (DDM) let the switch report temperature, laser power and received light, so a dirty connector or a failing link shows up in the switch before users call.
Hot-swappable
Modules plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch to remove it.

Frequently Asked Questions
Singular Expert Insight
We offer the AR-SFP-10G-LR-ST as the cost-effective alternative to Arista’s own LR optic for single-mode links up to 10 km. Order both ends together so the coding and wavelength match. For short in-rack links a DAC or SR optic is cheaper. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status from the switch and we help you find out whether it is the optic, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.
Buyer’s Guide
Buy it if
You run Arista switches and need 10G single-mode links up to 10 km.
Skip it if
Your fibre is multimode, the link is inside one rack, or your switch is not Arista.
