Product information

Description

The TP-Link 1000Base-BX WDM Bi-Directional SFP Module is a compact metallic fiber optic transceiver compatible with standard SFP interfaces. It supports 1000Base-BX and WDM bi-directional technology to transmit and receive on a single strand of fiber, enabling network extension up to 10 km at a line rate up to 1250 Mbit/s. The module uses an LC (UPC) connector, operates from an internal +3.3 V supply and is FCC/CE certified.

Advantages

This SFP module reduces fiber cabling costs by using WDM bi-directional transmission over a single fiber strand while maintaining gigabit performance. Its compact metallic housing and standard SFP form factor ensure wide compatibility with routers, switches and media converters. The plug-and-play design requires no configuration and the module is intended to be used in pairs (TL-SM321A with TL-SM321B) for correct wavelength pairing.

Suitable for

  • Extending Ethernet links up to 10 km over single-mode fiber
  • Integration with TP‑Link routers, switches and media converters
  • Replacing or upgrading SFP ports that require LC (UPC) connectors

Key specifications

  • Standard: 1000Base-BX (WDM Bi-Directional)
  • Data rate: up to 1250 Mbit/s
  • Wavelengths: TX 1550 nm / RX 1310 nm
  • Maximum distance: 10,000 m (10 km)
  • Connector type: LC (UPC)
  • Power supply: internal +3.3 V
  • Form factor: SFP, metallic housing
  • Certifications: FCC, CE

How to use

Insert the TL-SM321A SFP module into an available SFP port on a compatible device (router, switch or media converter). Use this module paired with a complementary TL-SM321B module at the remote end to achieve WDM bi-directional communication (different wavelength in each direction). Connect the LC (UPC) fiber cables and verify link status on both devices. No additional configuration is required for basic operation.

Usage recommendations

For reliable operation, use single-mode fiber rated for the stated distance, ensure correct pairing with TL-SM321B, and avoid bending the fiber beyond recommended radii. Verify device compatibility with standard SFP modules and confirm firmware or device notes if a vendor-specific restriction exists.
