Método de acondicionamiento y aparato para red de comunicación óptica |
摘要 |
A grooming apparatus for an optical communication network is disclosed. The apparatus mainly includes a first photoelectric integration unit and an electrical-layer grooming unit. The first photoelectric integration unit includes a wavelength division multiplexing/demultiplexing unit and a photo-electric/electric-photo conversion unit. The wavelength division demultiplexing unit is configured to demultiplex a multi-wavelength optical signal into single-wavelength optical signals. The photo-electric conversion unit is configured to convert the single-wavelength optical signals to single-wavelength electrical signals. The electrical-layer grooming unit is configured to groom the single-wavelength electrical signals. The present invention overcomes the fatal defect of light dispersion, light power estimation, light power adjustment, OSNR limitation for a conventional OADM/ROADM system. Also, the flexibility of the electrical-layer grooming eliminates the wavelength broadcast and multicast issue. The processing of the electrical layer also addresses the wavelength monitoring issue and the wavelength conflict issue.
