TP-Link TL-SM321A, 1G SFP optical module WDM, SM, 1550nm, 1x LC connector, 20km

Product detailed description

The TP-Link TL-SM321A supports the 1000Base-BX standard and transmits Gigabit Ethernet over a single-mode (SM) fiber, using a different wavelength for each direction of communication. On the opposite side of the fiber optic link, you can use, for example, a TP-Link TL-SM321B SFP module or a TP-Link TL-FC311B-20 media converter. With TP-Link routers, switches and media converters, you can extend the network range up to 20 km while ensuring high speed and stability. Notice WDM modules must be used in pairs, i.e. A and B - see related products for the counterpart.
