Abstract

The invention discloses an adjustable all-optical signal format conversion assembly, device and conversion method, relates to the field of communication systems, and solves the problems that in the prior art, a photoelectric-optical conversion mode is adopted for 8QAM format conversion, signal transmission time delay is increased, high-speed large-capacity transmission of data traffic is not facilitated, and the conversion efficiency is high. A coupler, a high-nonlinearity optical fiber, a phase shifter and an attenuator are used for forming a nonlinear optical loop mirror, the nonlinear optical loop mirror is used for adjusting the amplitude state of an 8QAM signal, parameters of all assemblies in the nonlinear optical loop mirror are set, and the 8PSK or rectangular 8QAM signal is obtained. Therefore, network attacks on an electric layer can be effectively prevented, the processing of all-optical format conversion on signals of different modulation formats avoids a photoelectric-optical conversion mode, signal transmission time delay is reduced, and transmission of data traffic in a high-speed large-capacity transmission line is easier.

Description

technical field [0001] The invention relates to the field of communication systems, more specifically, it relates to an adjustable all-optical signal format conversion component, device and conversion method. Background technique [0002] With the rapid growth of data traffic in the network, the optical transport network has become the supporting network for high-speed data transmission. All-optical information processing technology can reduce the processing delay of network nodes and improve transmission bandwidth. At the same time, due to different network types such as long-distance networks and short-distance networks, the signal modulation formats for carrying data traffic are also different. Therefore, at network nodes, it is of great significance to construct all-optical format conversion nodes for existing modulation formats. As a high-order modulation signal, 8QAM signal is widely used in high-speed and large-capacity optical network, and different network types n...
