Problems solved by technology
[0007] In the process of realizing the present invention, the inventor finds that the prior art has at least the following defects: Although the first method satisfies different output specification requirements through different interface boards, it causes waste of board resources and increases the Equipment cost and maintenance cost
Although the second method satisfies the unification requirement of output specifications, the cost is still high for some cost-sensitive devices
Moreover, the interface of the equipment panel is occupied, which brings difficulties to the miniaturization design of the equipment

Embodiment Construction
[0019] figure 1 It is a flow chart of an embodiment of a method for switching an optical transmission physical channel in the present invention. Examples of the method include:
[0020] Step 11, detecting the optical transmission rate of the optical module;
[0021] Step 12: Control the switch according to the detected optical transmission rate to select a physical channel with a corresponding rate to connect to the optical module.
[0022] In the above step 12, the switch may be a high-speed electronic switch, and may be an alternative switch. When it is necessary to switch more physical channels with different rates, the corresponding multi-choice switch can be selected according to the number of physical channels.
[0023] The above step 12 selects the physical channel of the corresponding rate according to the optical transmission rate control switch to connect with the optical module may include:
[0024] When the optical transmission rate is a 100M bit rate, select ...

The invention discloses a method for switching optical transmission physical channels and a physical interface device. The method comprises the following steps: detecting the optical transmission rate of an optical module; and controlling a switch according to the optical transmission rate to select a physical channel with a corresponding rate and connect the channel with the optical module. The device comprises physical channels with different rates, a detection module, a control module and a 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 detection module into a control signal and controlling the switch to select the physical channel with the corresponding rate and connect the channel with the optical module. By applying the method and the device, the physical channels with different rates can share one physical interface device so that the cost of the device during transmission, volume expansion and upgrading is greatly reduced.
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...
