Black Box 6.5ft OS2 LC-LC Singlemode Fiber Optic Patch Cable (Yellow)

The Black Box EFN310-002M-LCLC is a 6.5 foot patch cable that uses OS2 singlemode fiber and an LC connector at each end. It gives network teams a simple, reliable way to carry high-speed data over distances that would challenge multimode fiber.

The cable’s 9/125 micron glass maintains an insertion loss of about 0.2 dB, so signals stay clean on 1310 nm and 1550 nm wavelengths. That low loss, combined with high return loss, helps keep links stable in applications such as backbone runs, storage networks, or carrier-class equipment interconnects.

Each plug follows the LC format, which saves rack space and fits densely populated patch panels or desktop adapters. The outer jacket is made from PVC with an OFNR fire rating, allowing safe installation in riser spaces. A yellow sheath clearly identifies the cable as singlemode during maintenance or troubleshooting.

The operating range of -4 to 158 °F covers typical wiring closets, data center aisles, and office environments. Use the cable to patch a switch to a patch panel, link a media converter on the bench, or extend an optical transceiver on a workstation. Installers, administrators, and lab technicians will appreciate the dependable performance that Black Box products are known for.
