Product information

Description

The TP-Link Omada Gigabit Single-Mode WDM Bi-Directional SFP Module TL-SM321A-2 is a reliable fiber optic network transceiver designed to establish high-speed connections over single-mode fiber infrastructure. Featuring an SFP interface and supporting a maximum data transfer rate of 1250 Mbit/s, this module ensures efficient data transmission for professional network environments. It operates on an input voltage of 3.3 V and meets RoHS, CE, and FCC compliance standards, providing a secure and stable hardware solution for expanding network infrastructure.

Advantages

This module utilizes WDM Bi-Directional technology, allowing data to be transmitted and received over a single strand of fiber using different wavelengths in each direction, which helps optimize cabling costs and resources. It supports hot-swapping for convenient installation and maintenance without powering down network devices. Built to integrate seamlessly with various compatible network switches and media converters, it offers flexible deployment options for expanding existing network topologies.

Suitable for

  • Expanding professional network infrastructure over single-mode fiber
  • Connecting compatible network switches and media converters
  • Upgrading local area network data transfer capabilities up to 1250 Mbit/s

When it may not be suitable

This module is not suitable for multi-mode fiber optic cabling infrastructures, as it is specifically engineered for single-mode fiber use. It may also not be compatible with network hardware from brands that require strict proprietary transceiver locking.

Key specifications

  • SFP transceiver type: Fiber optic
  • Maximum data transfer rate: 1250 Mbit/s
  • Interface type: SFP
  • Input voltage: 3.3 V
  • Compliance certificates: RoHS, CE, FCC

How to use

To use the module, ensure that the network device is powered on if hot-swapping is supported, or power off the device according to the manufacturer guidelines. Carefully insert the SFP module into the available SFP slot on the compatible network switch or media converter until it clicks securely into place. Connect the appropriate single-mode fiber optic cable with an LC interface to the module port. Verify the link status through the network management interface to ensure a stable connection is established.

What to consider before purchase

  • Verify compatibility with your existing network switches or media converters
  • Confirm that your current cabling infrastructure utilizes single-mode fiber
  • Check the required transmission distance and matching paired module requirements
Usage recommendations: Handle the optical transceiver with care to avoid contamination of the optical bore. Always use dust caps when the fiber optic cable is disconnected, and ensure network compatibility before deployment.
