TL-SM321A 1G Base-BX WDM Bi-Directional SFP Module (20km)

Overview

The TP-Link TL-SM321A 1G Base-BX WDM Bi-Directional SFP Module is a fiber transceiver module designed for long-distance Gigabit Ethernet fiber connectivity. It operates on single-mode fiber using Wavelength Division Multiplexing (WDM) technology, allowing bi-directional data transmission over a single fiber cable. This module supports transmission distances of up to 20km, making it ideal for enterprise networks, ISPs, and data centers.

How to Install and Use

1. Unbox the TL-SM321A and inspect for any physical damage.

2. Power off the switch or router before inserting the module.

3. Insert the module into an available SFP slot, ensuring a firm connection.

4. Connect a single-mode fiber optic cable to the module.

5. Ensure the other end of the cable is connected to a compatible TP-Link TL-SM321B module.

6. Power on the switch or router to allow automatic detection.

7. Verify connectivity via the switch’s web interface or CLI.

8. Test data transmission for stable operation.
