Signalling of wavelength divison multiplex networks for fibre-optic communication and transmission method for control information

本发明涉及一种以数字化方式进行光纤信息通信传输的波分复用网络的附加信息的传输方法。按照本发明，所述附加信息是通过与用户信息相同的光信道，特别是以与用户信息相同的波长传输的。附加信息是独立于用户信息编解码的，这样就独立于用户信息而被访问。采用时分多路复用方法使得可对用户信息和附加信息进行不同的编码，从而大大减小与传输附加信息有关的无源光网络的技术复杂性。由此，本发明提供一种在光学WDM网络中简单、经济和透明地传输附加信息的方法。 A method for transmitting signaling and control information for wavelength-division multiplex networks for optical, fiber-bound information transfer in digitized form, the signaling and control information being transmitted via the same optical channel, particularly with the same wavelength, as the useful information, but being encoded and decoded independently thereof, with the result that the control and signaling information can also be accessed independently of the useful information. The use of a time-division multiplex method allowing the different encoding of useful information and control information makes it possible considerably to reduce the technical complexity of passive optical network elements with regard to the routing of the signaling and control information. This method permits the simple, low-cost and transparent transmission of signaling and control information in the optical WDM network.
