The SAFENET II draft Military Handbook, MCCR-0036-DRAFT, establishes requirements and provides guidance for the implementation of a Survivable Adaptable Fiber Optic Network. SAFENET II. The fiber optics communications channel essentially adopts the ANSI Fiber Distributed Data Interface FDDI physical Layer Medium Dependent PMD specification, modified by a requirement for increased transmitter optical output power and decreased minimum receiver optical input power increased sensitivity to provide a 21 dB overall optical flux budget between and including the equipment fiber optic interface connectors FOIC. A network of cables, optical bypass switches, and spliced fiber joints is described in the Handbook which permit ring operation through up to 5 bypassed nodes while maintaining a minimum 6 dB link optical power margin.
