Single-Unit is RoHS 3 compliant and all multimode and singlemode cables (except OM1) utilize bend-insensitive optical fibers. Each fiber is color coded for easy identification, flexible and easy to handle with lightweight aramid yarns to enhance strength. Single-Unit constructions are an ideal intra-building cable solution that will support applications including Gigabit, 10 Gigabit and 40 Gigabit Ethernet. Proterial Cable America is proud to utilize Corning Optical Fiber as our standard optic fiber.
