RESERVING METHOD FOR SYNCHRONOUS FIBER-OPTIC COMMUNICATION NETWORK WITH SPECTRAL PACKING SYSTEMS Russian patent published in 2007 - IPC H04B10/00 

FIELD: optical systems, namely communication networks, possible use in synchronous fiber-optic communication networks, both existing and in development.

SUBSTANCE: in accordance to the invention, sets of lengths of optical cables of communication network are selected, breakdown of each of which disrupts all routes between corresponding communication network units and value of total structural reliability coefficient of which is less than allowed, and installed into system are spectral packing terminals, optical routing commutators, optical multi-port commutators, optical power indicators and control blocks in units of communication system, incidental to lengths of cable of communication line, which compose selected sets, with following switching of information traffic to spectral packing terminal in case of loss of optical power in one of optical fibers.

EFFECT: reduced material costs of building of communication network, while preserving its reliability.
