Product information

Description

TP-Link TL-SM321A is a single-strand fiber SFP transceiver module that implements the 1000Base-BX standard. The module supports bidirectional transmission over one optical fiber using different wavelengths in each direction and provides a maximum data transfer rate of 1250 Mbit/s. It operates from a 3.3 V supply, comes in a metallic housing and is CE and FCC certified for interoperability and regulatory compliance.

Advantages

The TL-SM321A enables duplex communication over a single fiber, reducing cabling requirements and enabling long-distance links up to 10 km when paired with a compatible WDM module. Its SFP form factor ensures hot-pluggable installation in switches and media converters, while the metallic enclosure improves mechanical durability and thermal performance.

Suitable for

  • Extending Gigabit Ethernet links up to 10 km in enterprise or campus networks
  • Use with TP-LINK TL-SM321A, MC112CS or compatible third-party WDM modules for single-fiber duplex links
  • Installation in switches, routers or media converters with SFP ports

Key specifications

  • Interface type: SFP
  • Standard: 1000Base-BX (single strand, bidirectional)
  • Maximum data transfer rate: 1250 Mbit/s
  • Operating voltage: 3.3 V
  • Link distance: up to 10 km (with compatible WDM module)
  • Certifications: CE, FCC
  • Product colour: Metallic

How to use

Insert the TL-SM321A into an available SFP slot on a compatible switch, router or media converter while the device is powered on or off per the host equipment instructions. Connect the fiber cable to the transceiver using the appropriate connector and ensure the paired module at the far end supports the complementary wavelength for BX operation. Verify link status indicators on host equipment and configure network settings as required.

Usage recommendations

Use the TL-SM321A together with TP-LINK TL-SM321A, MC112CS or other compatible WDM modules that support the complementary transmit/receive wavelengths. Ensure fiber type and connectors match host equipment requirements and observe ESD precautions when handling the SFP module.
