TP-Link TL-SM321B-2 - Gigabit SFP module, WDM, SM, 2km, 1310/1550nm

Product detailed description

The TP-Link TL-SM321B-2 is a Single mode WDM SFP module with a wavelength of 1310/1550nm (Tx/Rx), which is used for bidirectional connection over only one optical fiber, allowing you to double the link density without the need to replace the optical path. The SFP module supports monitoring, or DDM function. The module can be used over a distance of 2km via a single mode cable terminated with an LC connector. For a fully functional route, a module (TL-SM321A-2) with the opposite wavelength is required on the other side of the route.
