Used SFP Modules in Kenya, Link-Tested

Tested, not refurbished

Plenty of sellers call used optics refurbished. We do not, because it is not what happens. Refurbishing implies reconditioning, and there is nothing inside a transceiver to recondition: no moving part, no consumable, nothing that wears.

What we do is test. Every used module is cleaned, inspected, powered up and link-tested in hardware matching the platform it is coded for, then graded on cosmetic condition, because a module either passes the optical and electrical tests or it does not go on the shelf.

A used optic that passes those tests performs identically to a new one, which is why we back both with the same 12-month warranty.

When to buy new instead

If your support contract or tender requires factory-sealed parts with an unbroken chain of custody, buy new. If you are filling an access layer, building a lab, or keeping spares on the shelf, used is usually the better use of the budget.
