10G LR SFP Modules

LR stands for "Long Range," indicating the transceiver's transmission distance capability. In 10GBASE-LR SFP+ modules, LR designates support for links up to 10km over single-mode fiber, distinguishing it from short-range (SR) optics limited to multimode fiber and shorter distances, typically under 400 meters.

10G LR SFP+ modules use single-mode fiber (SMF), not multimode. The single-mode design, paired with a 1310nm laser wavelength, allows signals to travel up to 10km without significant attenuation, making it suitable for longer data center and campus interconnects compared to multimode SR optics.

Yes, when sourced from a reputable reseller. Terabit Systems' refurbished 10G LR SFP+ optics undergo a rigorous 5-step QA and testing process to verify optical performance, connector integrity, and compatibility before shipment, and are backed by a 1-year replacement or refund warranty for added assurance.

Compatibility depends on the switch vendor and platform. Brocade 10G-SFPP-LR modules are designed for Brocade equipment, while Juniper EX-SFP-10GE-LR modules are built for Juniper EX Series switches. Confirm your specific hardware model when ordering to ensure proper interoperability and firmware support.

Most 10GBASE-LR SFP+ modules, including the Brocade and Juniper options offered, use LC connectors. LC connectors are compact duplex connectors standard for single-mode fiber applications, allowing straightforward integration with existing single-mode fiber patch panels and cabling infrastructure in data centers.

Pricing varies by manufacturer and model. Refurbished Brocade 10G-SFPP-LR modules are listed around $2,745 MSRP, while Juniper EX-SFP-10GE-LR modules list around $4,000 MSRP. Volume and custom pricing may be available, and refurbished units typically cost significantly less than new OEM equivalents.
