TL-SM321B-2 1G Base-BX WDM Bi-Directional SFP Module (2km)

Overview

The TP-Link TL-SM321B-2 1G Base-BX WDM Bi-Directional SFP Module is a high-performance SFP transceiver designed for long-distance, single-fiber bidirectional communication. It enables efficient and cost-effective fiber-optic network expansion, ideal for enterprise and service provider applications requiring up to 2 km transmission range.

Installation & Usage

1. Unboxing & Inspection - Ensure the package includes the TL-SM321B-2 module and a user manual.

2. Switch Compatibility Check - Verify that the switch or router supports BiDi SFP modules and has a compatible WDM counterpart (TL-SM321A-2).

3. Insertion into SFP Slot - Carefully insert the TL-SM321B-2 into an available SFP slot on a compatible device.

4. Fiber Cable Connection - Use a single-mode fiber-optic cable with an LC connector to connect the module to another WDM-compatible device.

5. Pairing with TL-SM321A-2 - Ensure the module is connected to a TL-SM321A-2 transceiver for bidirectional operation.

6. Power On & Initialization - Power on the switch/router and verify LED indicators for connection status.

7. Testing & Monitoring - Use network management tools to monitor link stability and performance.

Services, Licenses, and Plans

The TL-SM321B-2 1G Base-BX WDM Bi-Directional SFP Module is a hardware-based solution that does not require any additional licenses or subscription plans. It is a plug-and-play module designed for seamless integration with TP-Link and third-party networking equipment.

Key Differences

• TL-SM321B-2 (Single-Fiber, WDM BiDi): Supports 1.25 Gbps data rate over a single fiber with an LC connector.

• TL-SM321A-2: Required counterpart for bidirectional communication.

• Dual-Fiber SFP Modules: Require two fiber strands instead of one, increasing cable requirements.
