Abstract

A dispatch device in optical communication network is prepared as forming photoelectric integrated unit by wavelength division multiplexing / de-multiplexing component for decomposing multi-wavelength optical signal to be multiple single wavelength optical signal and photoelectric / electro-optic conversion component for converting single wavelength optical signal to be single wavelength electric signal, and using electric layer dispatching unit to dispatch electric signal of single wavelength.

Description

technical field [0001] The invention relates to scheduling technology in communication, in particular to a scheduling device and a scheduling method in an optical communication network. Background technique [0002] With the rapid growth of packet services, future communication network design should focus on optimizing support for packets, especially IP services. Therefore, it is very important to improve service scheduling capabilities and achieve high-efficiency service transmission. At present, the scheduling methods mainly include: wavelength-level electrical crossover or optical crossover, such as reconfiguration optical add / drop multiplexing (Reconfiguration Optical Add / Drop Multiplexing, ROADM), which can selectively transmit up and down local services and certain wavelengths, and Transmission of other wavelengths is not affected. [0003] The existing ROADM is ROADM based on wavelength selective switch (Wavelength Select Switch, WSS). Its structural block diagram is...
