Specialty Multi-Mode Fibers Nufern’s specialty multi-mode fibers are ideal for a variety of diverse applications. They are capable of withstanding extreme environments and large temperature swings. Features include step index and graded index configurations, numerical apertures from 0.06 to 0.45 and core sizes from 10 μm to 700 μm. All fibers are available with a high temperature acrylate, silicone, or polyimide coating. Typical Applications Features & Benefits • Telecom FDDI, FTTH, etc. • Operate over wide frequency range — One fiber serves broad applications • Optical pump & beam delivery • Exceptional uniformity and core/clad concentricity — Minimize fiber induced signal artifacts • Robust duty in extreme • Higher proof test levels — Longest life expectancy environments • CATV and data comm.
