PASSIVE OPTICAL COMMUNICATION NETWORK OF WAVELENGTH DIVISION MULTIPLEX SYSTEM WITH LIGHT SOURCE OF SELF-IMPLANTATION LOCKED FABRY-PEROT LASER DIODE

摘要

PROBLEM TO BE SOLVED: To provide a passive optical communication network of a wavelength division multiplex system which can align a wavelength of an optical signal with a passband wavelength of a waveguide type lattice router in the passive optical communication network of a wavelength division multiplex system without a temperature monitoring function.

SOLUTION: The passive optical communication network of the wavelength multiplex system is characterized to include a central base station which creates downward optical signals of different wavelengths each other, and receives upward optical signals of different wavelengths each other; local base stations which are connected to the central base station through a first optical fiber, and have wavelength distribution units that are set to reflect the wavelength already established; and a plurality of optical subscribers which are connected to the local base stations through a second optical fiber; and the respective optical subscribers have light sources which oscillate in multiplexing modes, generate the upward optical signals in a single mode by self-implantation locked by the established wavelength, and offer to the local base stations through a third optical fiber.
