The TP-Link TL-SM321B 1000Base-BX WDM bi-directional SFP module connects network switches, routers, and media converters to fibre optic networks. It fits into standard SFP slots and supports data transfer rates of up to 1.25 Gbit/s. By using WDM technology to transmit and receive data on different wavelengths, the module allows both traffic paths to operate over a single fibre strand, reducing cabling requirements.
Cables connect via the unit’s LC simplex connector. The integrated optics transmit at a wavelength of 1430 nm. The module complies with the IEEE 802.3z standard and requires a compatible transceiver at the other end of the link.
Key Features:- Supports distances up to 20 km
- Designed for single-mode fibre (SMF)
- 1000 Mbit/s Ethernet data rate
- Integrated Digital Diagnostics Monitoring (DDM)
