The SMFIBLCSC7 7m LC to SC single-mode duplex fiber cable features 9/125 micron fiber for high-speed, high bandwidth data transmissions over Gigabit Ethernet and fiber channel networks, with support for duplex single-mode applications. This LC-SC patch cable is housed in a LSZH (Low-Smoke, Zero-Halogen) flame retardant jacket, to ensure minimal smoke, toxicity and corrosion when exposed to high sources of heat, in the event of a fire - an ideal solution for use in industrial settings, central offices and schools, as well as residential settings where building codes are a consideration. Each duplex 9/125 (OS1) single-mode fiber patch cable is individually tested and certified to be within acceptable optical insertion loss limits for guaranteed compatibility and 100% reliability and is backed by our lifetime warranty.
