Arista 10GB Transceivers - SFP+ | Refurbished, Used, New
Arista 10G SFP+ transceivers are the hot-swappable optics that give Arista 7050, 7150, 7280 and 7500 switch ports a 10G link over fiber, copper or a DWDM wavelength. The same SFP+ cage takes a short-reach multimode optic for a rack-to-rack link, a long-reach single-mode optic for a building or campus run, an RJ45 copper module for an existing Cat6a cable, or a tunable DWDM module for a metro wavelength. NetworkTigers sells Arista SFP-10G-SR, SRL, LR, LRL, ER, ZR, T and DZ-T modules refurbished, used and new. Every transceiver is tested in a switch before it ships so it links up when it arrives.

Which Arista 10G SFP+ do I need?
Start with the cable you already have. Orange or aqua multimode fiber takes SFP-10G-SR or, for runs under 100m, the lower-cost SFP-10G-SRL. Yellow single-mode fiber takes SFP-10G-LRL for up to 1km, SFP-10G-LR for up to 10km, SFP-10G-ER for up to 40km and SFP-10G-ZR for up to 80km. Both ends of a link must use the same standard, so pair an LR with an LR, not with an SR. For a server or firewall that only has an RJ45 port, SFP-10G-T runs 10G over Cat6a up to 30m, but it draws more power than a fiber optic and some older switch generations limit how many copper modules a port group accepts, so check your switch before filling a row with them. SFP-10G-DZ-T is for carrier and campus DWDM systems where you set the module to a specific C-band channel. For links inside one rack, a DAC cable is usually cheaper than two optics and a patch cord.
Frequently asked questions
Do Arista switches accept these optics in 1G mode?
SFP+ cages on most Arista switches accept 1G SFP optics as well, but a 10G optic such as SFP-10G-SR runs at 10G only. If you need a 1G link to a legacy device, use a 1G optic or an SFP-10G-T, which negotiates down to 1G on supported switches.
Will an SFP-10G-SR work on OM1 or OM2 fiber?
It links, but reach drops sharply, roughly 26m to 33m on OM1 and 82m on OM2. If the run is short, it is usually fine. For anything longer, plan on OM3 or OM4 fiber or move the link to single-mode.
Do these optics report light levels on the switch?
Yes. Arista SFP+ optics support digital optical monitoring, so the switch shows transmit and receive power, temperature and voltage per port. That is the first place to look when a link comes up with errors or will not come up at all.
