Optical waveguide plate and optical fiber coupling connection method, optical waveguide plate and communication transmission system

Abstract

The invention provides an optical waveguide plate and optical fiber coupling connection method an optical waveguide plate and a communication transmission system, which belongs to a communication system. The optical waveguide plate is processed to form a connection groove. The bottom of the groove comprises the core layer of optical waveguide. An optical fiber connection end is embedded into the connection groove, and an optical fiber core layer and the optical waveguide core layer are in butt joint. Compared with the prior art, the connection method, the optical waveguide plate and the communication transmission system have the advantages that the method that a guide pin is inserted into grooves on both sides of an optical waveguide plate core layer to realize the butt joint of the optical fiber core layer and the optical waveguide core layer is eliminated; the optical waveguide plate is processed to form the connection groove; the groove directly accommodates the optical fiber connection end, so that the optical fiber core layer and the optical waveguide plate core layer are in direct butt joint; accurate alignment and connection are realized; the impact of vibration, collision and other environmental forces is avoided; the alignment accuracy of the optical fiber core layer and the optical waveguide plate core layer is improved; the transmission stability of communication transmission is improved; the optical fiber connection end does not need a guide pin; the optical fiber connection end is simply processed; and the core competitiveness of a product is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for coupling and connecting an optical waveguide plate and an optical fiber, an optical waveguide plate and a communication transmission system. Background technique [0002] The rapid development of broadband communications, supercomputers and big data centers has continuously promoted the rapid growth of information transmission bandwidth. The limitations of traditional electrical interconnection technologies in terms of bandwidth, distance, and energy consumption have become more and more prominent. The transmission bandwidth of 10Gbps Electrical interconnection technology can only realize information transmission at a distance of 0.3m to 1m, but it is helpless for high-speed interconnections such as 25Gbps and 40Gbps. In recent years, the optical printed backplane interconnection technology based on the optical waveguide theory has gradually developed, and has been widely s...
