1000BASE-LX SFP Modules

In SFP terminology, 'LX' stands for 'Long Wavelength'. This designates the transceiver for long-reach applications, typically over single-mode fiber optic cables. This contrasts with 'SX' or 'Short Wavelength' modules, which are designed for shorter distances over multimode fiber. LX modules are the standard for links up to 10 km.

1000BASE-LX SFP modules are designed primarily for use with single-mode fiber (SMF) to achieve their maximum reach of up to 10 km. While they can sometimes operate over short distances on multimode fiber (MMF) with a special mode-conditioning patch cable, their standard and optimal application is with single-mode fiber for long-distance connectivity.

The standard maximum transmission distance for a 1000BASE-LX SFP module over single-mode fiber is 10 kilometers (approximately 6.2 miles). This makes them a reliable choice for connecting buildings across a campus, linking data centers, or for service provider network extensions where long-distance, high-speed connectivity is required.

Absolutely. Every SFP module we sell undergoes a rigorous 5-step Quality Assurance and testing process to ensure it meets or exceeds original manufacturer specifications for performance and reliability. We stand behind our hardware with a rock-solid warranty, giving you peace of mind and dependable network operation.

Our 1000BASE-LX SFP modules are backed by a comprehensive warranty, which includes a 1-year replacement or full refund guarantee if you encounter any issues. This commitment to quality ensures you receive hardware that performs reliably from day one, protecting your investment and minimizing network downtime.

Our modules are tested for compatibility with their respective manufacturer's equipment, such as Juniper EX Series switches or Brocade routers. To ensure compatibility, please verify the product identifier (e.g., EX-SFP-1GE-LX) matches the requirements for your specific device. Our technical support team is available to assist with any compatibility questions.
