IF 636-0-3 is a high-speed single-mode fiber optic cable developed by Industrial FiberOptics, Inc. It is designed for Ethernet, Fast Ethernet, and Gigabit Ethernet applications, and also for very high-speed applications such as 10G and 40G Ethernet. The cable is designed to industry standards and is very tough, with superior resilience to withstand temperature extremes and ambient moisture. Its low-loss characteristics make it an ideal choice for long distance links. The cable has an orange sheath that is flame retardant, a Kevlar strength member, a black-coloured non-refractive jacket, and rugged stainless steel connectors that make it suitable for outdoor installation.
