Used SFP Modules in Kenya, Link-Tested
Link-tested, graded and warrantied for twelve months, at a fraction of the price of new.
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.
