Optical back plate interconnection system and communication equipment

Abstract

The embodiment of the invention provides an optical back plate interconnection system and communication equipment. The optical back plate interconnection system comprises a back plate, a front insertion plate, a rear insertion plate and a connector; the front insertion plate and the rear insertion plate are respectively arranged at the two side of the back plate, are orthotropic with each other and are both provided with an optical waveguide channel; and the optical waveguide channels are butted through the connector connected on the back plate to form a light path passed through by optical signals for realize optical signal transmission. In the embodiment of the invention, the front insertion plate and the rear insertion plate are respectively arranged at the two sides of the back plate and are arranged orthotropically with each other and the optical waveguide channels in the front insertion plate and the rear insertion plate are butted directly through the connector to form the light path, thereby realizing the optical signal transmission, shortening an optical link and reducing the loss of the optical signals. In addition, since the optical waveguide channels are adopted, the system can achieve better processing performance and reduces the complexity of the physical implementation of a high-density optical fiber back plate.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to an optical backplane interconnection system and communication equipment. Background technique [0002] In the communication system, as the signal rate continues to increase, the access capacity of the equipment becomes larger and larger, and the system bandwidth increases accordingly. Among them, increasing the number of buses is one of the ways to increase the system bandwidth, but due to the limitations of chip technology, process technology, heat dissipation, etc., the realization of large-capacity electrical interconnection systems is becoming more and more difficult, and optical interconnection due to low loss , low crosstalk, high density, and channel characteristics have nothing to do with the rate and other advantages, the optical backplane interconnection system becomes a better solution. [0003] The optical backplane interconnection system used in the ...

Problems solved by technology

However, in the process of realizing the present invention, the inventors found that the signal loss of the optical waveguide itself is relatively large, and the optical link in this solution is relatively long, resulting in a greater loss of optical signals and a decrease in signal transmission quality
