These devices may be used for driving data across single or multi-mode optical fiber. The fiber may either be the "local loop" of an end-to-end leased line, or just a point-to-point local communication circuit.

red_arrow They allow data devices to benefit from optic fiber's immunity to electrical and electromagnetic noise and interference, reduced data errors, and increased equipment safety and reliability.
red_arrow Variety of DTE interfaces. Some models provide multiple DTE interfaces to allow several connected devices to share the fiber link.
red_arrow All models support both Single Mode and Multimode Fiber. Some of them offer the option of a second, hot standby fiber link.
