Fiber Optic Modems and Multiplexers
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.
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.
Variety of DTE interfaces. Some models provide multiple DTE interfaces to allow several connected devices to share the fiber link.
All models support both Single Mode and Multimode Fiber. Some of them offer the option of a second, hot standby fiber link.
