Tunable multichannel optical network

Optical networks with tuned architecture intending to internetworking with Ethernet connection and possessing improved resistivity to unfavorable external influences are considered. The main operation principle is using of a photoelectrical supply mode for Ethernet RJ45 to Fiber Optic Media Converter. An offered schematic can involve as electro-optical converters as Erbium Doped Fiber Amplifiers with remote optical pumping. Especially for presented network routing architecture is designed. The offered technics can be applied also both for Free Space Optics and Quantum Criptography Protected Systems. Recommendations on practical application are given.
