DESCRIPTION ADDITIONAL INFORMATION REVIEWS

Upgrade your network with the TP-Link TL-SM321B-2 Bi-Directional SFP Module. This powerful fiber optic transceiver helps you connect devices over long distances using just one single-mode fiber cable, thanks to its clever Bi-Directional (BiDi) WDM technology.

It's designed to deliver reliable gigabit speed connections up to 2 kilometers (about 1.2 miles) away, making it perfect for extending your network between buildings, across large campuses, or to remote areas. The TL-SM321B-2 uses the 1000Base-BX standard, ensuring fast and stable performance.

Key features make this TP-Link SFP module easy to use and manage:
* **Long-Distance Reach:** Connect devices up to 2 km with 9/125 µm single-mode fiber.
* **Single Fiber Solution:** Bi-Directional WDM technology means you only need one fiber cable for both sending and receiving data, saving you money and simplifying wiring.
* **Easy to Install:** It's hot-swappable, meaning you can plug it into your compatible switch or media converter without having to turn off the device, keeping your network running smoothly.
* **Smart Monitoring (DDM):** With Digital Diagnostic Monitoring (DDM) support, you can keep an eye on how your module is performing, helping you troubleshoot issues faster.
* **Universal Compatibility:** Meets the SFP-MSA standard, so it works with many different SFP-compatible networking devices.

Whether you're setting up a new fiber optic link or expanding an existing gigabit network, the TP-Link TL-SM321B-2 provides a robust and efficient solution
