Used Arista Compatible QSFP-100G-SR4 100GBASE 850nm 100M QSFP Transceiver Module

Need a 100G module for your network gear without paying retail?

Here's a used Arista-compatible QSFP-100G-SR4.

It's rated for 100GBASE, runs at 850nm, and is good for up to 100 meters over multimode fiber.

This one's been used—might have a little scuff from being in a switch—but it's fully tested and works like it should.

Could be a pull from an old setup or a return.

If you're labbing or expanding on a budget, these are perfect.

No brand name on this one, just solid performance.
