TP-Link TL-SM321A 1000Base-BX WDM Bi-Directional SFP Module

The TP-Link TL-SM321A 1000Base-BX WDM Bi-Directional SFP Module is a high-performance fiber optic transceiver designed for Gigabit Ethernet (1000BASE-BX) applications. TP-Link TL-SM321A It primary uses Wavelength Division Multiplexing (WDM) technology to enable bi-directional data transmission over a single fiber strand. TP-Link TL-SM321A module operates with 1000Base-BX and is designed for long-distance communication, with a reach of up to 20 kilometers (km).

TP-Link TL-SM321A has a bi-directional design of the TL-SM321A also allows it to transmit and receive data on different wavelengths, which improves network efficiency and reduces the need for multiple fiber cables. The module uses LC connectors and is compatible with SFP ports on switches, routers, and other network equipment, providing a reliable and cost-effective solution for expanding network infrastructure.

This SFP module is ideal for applications where long-distance, high-speed data transmission is required, and it is particularly suitable for fiber-optic networks in data centers, campus networks, and enterprise environments.
