TP-Link Gigabit Single-Mode WDM Bi-Directional SFP Module

This TP-Link TL-SM321B SFP module dramatically simplifies network cabling by transmitting and receiving data over a single strand of single-mode fibre, using different wavelengths for each direction. It enables full-duplex Gigabit Ethernet connections without the need for a second fibre, reducing infrastructure costs and installation time. Designed to comply with the 1000Base-BX standard, this module is ideal for point-to-point links in enterprise, campus, or service-provider environments where fibre pairs are limited. The hot-pluggable form factor makes upgrading or replacing transceivers quick and trouble-free.

- Uses one single-mode fibre strand for bi-directional data transmission (WDM)

- Compliance with IEEE 802.3ah 1000Base-BX10-D standard

- Supports data transfer rates up to 1.25 Gbps with full-duplex operation

- Transmits on 1550 nm wavelength and receives on 1310 nm wavelength

- Maximum cable distance of up to 10 km over single-mode fibre (9/125 µm)

- Durable LC/UPC simplex connector interface

- Low power consumption and hot-pluggable LC interface for ease of deployment

- Digital Diagnostic Monitoring (DDM) for real-time performance tracking

Deliver high-speed, cost-effective connectivity with minimal cabling overhead.
