Optical transmission physical channel switching method and physical interface equipment

Abstract

The invention discloses an optical transmission physical channel switching method and physical interface equipment. The method comprises the following steps of: detecting the optical transmission rate of an optical module; and controlling a switch to select an optical transmission physical channel at a corresponding rate according to the optical transmission rate, and connecting the optical transmission physical channel and the optical module. The equipment comprises the optical transmission physical channels at different rates, a detection module, a control module and the switch, wherein the detection module is used for detecting the optical transmission rate of the optical module; and the control module is used for converting the optical transmission rate detected by the detection module into a control signal, controlling the switch to select the optical transmission physical channel at the corresponding rate, and connecting the optical transmission physical channel and the optical module. The embodiment of the invention can make the physical channels at the different rates share one piece of physical interface equipment, and greatly reduces the cost of the equipment in transmission capacity expansion and upgrading.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for switching a physical channel for optical transmission and a physical interface device. Background technique [0002] At present, in the Ethernet communication system, transmission at different rates requires different physical interface devices. For example, in the Ethernet communication interface device, the physical interface devices used for the 100M transmission rate and the Gigabit transmission rate are different, and a separate device needs to be provided to meet the transmission interface specification requirements. Therefore, there are separate interface devices to meet different transmission rate specification requirements. [0003] In some application scenarios where transmission specifications are upgraded and expanded, it is necessary to switch between optical interfaces of different rates, such as switching between 100M optical interfaces and Gig...
