Quick Overview

Why Choose the TP-Link TL-SM321B-2?

We understand that finding the right SFP module for your network can be challenging. That’s why we’ve designed the TP-Link TL-SM321B-2 to meet your needs for fast, reliable, and efficient fiber connections. Whether you’re setting up a small office network or managing a larger data center, this module ensures seamless communication over single-mode fiber.

Key Features

1. WDM Bi-Directional Communication

The TL-SM321B-2 uses Wavelength Division Multiplexing (WDM) technology to send and receive data on a single fiber. This means you can achieve bi-directional communication without needing two separate fibers, saving you time and resources.

2. High-Speed Data Transfer

With a data rate of 1.25Gbps, this SFP module delivers lightning-fast gigabit connections. It’s perfect for applications that require high-speed data transfer, such as video streaming, large file transfers, and more.

3. Digital Diagnostic Monitoring (DDM)

We’ve included DDM functionality, which is compatible with SFF-8472. This feature allows you to monitor real-time parameters like optical power, temperature, and transceiver current. It’s a great way to ensure your network is running smoothly and to troubleshoot any issues quickly.

4. Long Transmission Distance

The TL-SM321B-2 supports data transmission up to 2 km on ⁹⁄₁₂₅ µm single-mode fiber. This makes it ideal for short- to medium-distance fiber networks, such as those in office buildings or campuses.

5. Wide Compatibility

This SFP module works seamlessly with all TP-Link products that have SFP ports, including JetStream switches and the MC220L media converter. It’s also developed in accordance with the Small Form Pluggable Multi-Source Agreement (SFP-MSA), ensuring broad compatibility.

How to Use the TL-SM321B-2

1. Keep the Dust Plug On: Always keep the protective dust plug on the SFP’s optical bores until you’re ready to connect it. This prevents dust and debris from damaging the module.
   
2. Insert into SFP Port: Insert the module into the SFP port of your compatible device, such as a switch or router.
   
3. Connect the Fiber: Use an LC simplex fiber cable to connect the module to your network.
   
4. Monitor Performance: Use the DDM feature to monitor the module’s performance and ensure optimal operation.
   

Applications

The TP-Link TL-SM321B-2 is versatile and can be used in various scenarios, including:
- Enterprise Networks: Connect switches, routers, and servers in your office or data center.
- Campus Networks: Extend your network across multiple buildings.
- Telecommunications: Ensure reliable communication for service providers.
