Problems solved by technology

Both of the above two methods have disadvantages: the disadvantage of method 1 is that the dedicated electric regeneration board and wavelength conversion board will lead to the diversity of boards and increase the complexity of engineering construction and system maintenance; Bring waste of board resources
Although method 2 can implement functions such as service access, electrical regeneration, and wavelength conversion through the flexible combination of electrical layer crossover and separated tributary boards and circuit boards, it has disadvantages such as high cost and high power consumption, and the electrical crossover function also increases the point of failure

Abstract

The invention discloses reconfigurable add / drop multiplexer (ROADM) equipment, an optical network system and a transmission method, and relates to the field of optical communication. The ROADM equipment comprises a local uplink and downlink module used for providing an uplink port and a downlink port for transmitting an optical signal; a multifunctional service board card used for processing the received optical signal transmitted by the downlink port, and sending the processed optical signal to client equipment or the uplink port, wherein the processing comprises accessing, electric regeneration and wavelength conversion. According to the ROADM equipment, the optical network system and the transmission method provided by the invention, the multifunctional service board card simultaneouslysupporting the functions of accessing of customer, electric regeneration and wavelength conversion is provided, the simplification of equipment production and engineering configuration is facilitated, the construction cost is reduced, the functions of service accessing, electric regeneration and wavelength conversion can be flexibly configured, staffs only need to go to a site for configuring anoptical module of a client and connecting optical fiber of client equipment when the customer service is accessing, and thus the operating and maintenance cost is reduced.

Description

Technical field [0001] The present invention relates to the field of optical communication technology, in particular to a ROADM device, an optical network system and an optical signal transmission method based on the ROADM device. Background technique [0002] With the popularization of the Internet and the improvement of the level of social information, broadband networks have gradually become one of the most important infrastructures in human society, and optical fiber communication networks, as the physical foundation of broadband networks, are increasingly important. Wavelength Division Multiplexing (WDM) technology enables the mass bandwidth transmission capabilities of optical fiber media to be brought into play, and has become the core technology of optical fiber communication networks. The reconfigurable add / drop multiplexer ROADM (Reconfigurable Add / Drop Multiplexer) device based on the WDM wavelength to provide flexible optical add / drop and multi-directional scheduling ...
