Arista 100GB Transceivers - QSFP28 - Refurbished, Used, New
Arista 100G QSFP28 transceivers plug into the 100G ports on Arista 7050X, 7060X, 7280R and 7500R series switches to link spine and leaf switches, connect servers at 100G, and carry traffic between data halls and buildings. The QSFP28 form factor carries 100G as four 25G lanes, and the optic you choose sets the fiber type, the connector and the reach, from 70 m over multimode to 40 km over single-mode. NetworkTigers sells Arista-coded 100G QSFP28 optics for short-reach multimode, parallel single-mode and duplex single-mode links, refurbished, used and new. Every transceiver is tested before it ships so it links up when it arrives.

Which Arista 100G QSFP28 do I need?
Decide by the fiber you already have in the ground. Orange or aqua multimode (OM3 or OM4) inside a data hall takes SR4 or XSR4 over an MPO-12 trunk, or SRBD and SWDM4 over ordinary duplex LC patch cords, which lets you reuse the LC cabling that carried 10G and 40G. Yellow single-mode takes PSM4 over MPO for runs up to 500 m, or a duplex LC optic for everything else: DR for 500 m, FR, CWDM4 or LRL4 for 2 km, LR4 for 10 km, and ERL4 for 30 to 40 km links between sites. Both ends of a link must use the same optic type, since CWDM4 will not talk to LR4 and SRBD will not talk to SR4. If you are moving a 40G BiDi link to 100G, the SRBD is dual rate and runs 40G today over the same LC pair before you flip the far end. Tell us your switch model and EOS release and we will confirm the optic is supported.
Frequently asked questions
Can SR4 and PSM4 optics break out to 4x 25G?
Yes. Both use four separate fiber pairs through the MPO-12 connector, so with an MPO to 4x LC breakout cable and the port configured for 4x25G in EOS, one QSFP28 port connects to four SFP28 ports. Duplex optics such as LR4, CWDM4 and SRBD multiplex all four lanes onto one fiber pair and cannot break out.
Will a 100G QSFP28 optic run at 40G in a QSFP+ port?
Only the SRBD is built to run at both 40G and 100G. The other optics in this collection are 100G only, and a QSFP28 optic placed in a 40G QSFP+ port will not link. For 40G links, use the 40G QSFP+ collection.
Do these optics report light levels in EOS?
Yes. The optics carry digital optical monitoring, so show interfaces transceiver reports transmit and receive power, temperature and voltage per lane, which is the first thing to check when a 100G link will not come up.
