Description
TP-Link TL-SM321A-2 1000Base-BX WDM Bi-Directional SFP Module – High-Performance Gigabit Fiber Link
Extend your commercial networking range cleanly and cost-effectively with the TP-Link TL-SM321A-2 1000Base-BX WDM Bi-Directional SFP Module . Designed for switches, routers, and enterprise servers, this high-performance MiniGBIC transceiver enables ultra-fast gigabit optical transmissions over a single strand of single-mode fiber .
By leveraging advanced Wavelength Division Multiplexing (WDM), the TL-SM321A-2 transmits data at 1550 nm and receives at 1310 nm over one single fiber strand . This cuts physical cabling deployment costs in half by removing the need for traditional dual-strand fiber configurations .
Key Features & Performance Benefits
