TP-LINK SM321B WDM Bi-Directional SFP Module | Single-Fiber Gigabit

One strand of fibre. Two-way traffic. That's the whole point, and it saves you a cable run you'd otherwise be chasing through a ceiling or a trench.

The SM321B is a WDM bi-directional SFP module that handles full-duplex gigabit over a single fibre strand. You pair it with an SM321A at the other end and you've got a clean link without doubling your fibre count. Drop it in, check the link, walk away.

Only one left on the shelf. If this is the module your site needs, add to cart now so it's not gone by the time you're ready to order
