Abstract

The invention discloses a device and a method for generating spectral amplitude code marks based on a tunable optic filter. The spectral amplitude code mark generation device comprises a swept laser source, a random digital signal generator, a Fabry-Perot tunable optic filter and an electro-optic strength modulator; the swept laser source, the Fabry-Perot tunable optic filter and the electro-optic strength modulator are connected with one another; and the random digital signal generator is connected with the electro-optic strength modulator. The spectral amplitude code mark generation process can be finished only by one laser and one tunable optic filter, so that the sensitivity of the coding and marking speed of a spectral amplitude code mark exchange system is improved greatly, the structure of the spectral amplitude code mark generation unit is simplified and the marking speed is improved greatly; and meanwhile, the device and the method are simple and easy and have strong actual operability.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to the design of a spectral amplitude code mark generation device and method based on an adjustable optical filter. Background technique [0002] Since the beginning of the 21st century, with the rapid development of Internet services, the explosive growth of IP data volume and business volume has put forward higher requirements for communication networks. Although the transmission capacity of the optical communication backbone network has reached the Tb / s level, as an indispensable part of the optical communication network - the switching node still needs to perform optical-electrical-optical conversion and electrical domain processing on the data packets. Since the speed of electronic exchange and electronic information processing has reached the limit, it greatly restricts the transmission rate of the existing communication network, resulting in the "ele...
