Embodiment 1

[0027] Such as figure 2 shown above figure 1 The switch 10 in includes: a system controller 102 and at least two laser transceiver modules 104, wherein:

[0028] The system controller 102 is used to judge in turn whether each laser transceiver module currently has data from an optical communication device (data from an optical communication device connected (or bound) to it), and if so, reads out the data and transmits it. Give the laser transceiver module bound with the target address contained in the data, so that the data is transmitted to the optical communication device indicated by the target address in the form of laser light by the laser transceiver module bound with the target address (that is, the address is the optical communication equipment of the target address);

[0029] Each laser transceiver module 104 is used to receive and save the data sent in the form of laser light (that is, from the optical communication device (such as the first optical communication...

Embodiment 2

[0032] Such as image 3 As shown, each laser transceiver module 104 includes: a transceiver controller 1042, a modulation drive module 1044, a laser emitting tube 1046, and a laser receiving tube 1048, wherein: the laser emitted by the laser emitting tube 1046 is aimed at the laser beam of an optical communication device The receiving tube, and the laser emitted by the optical communication device is also aimed at the laser receiving tube 1048, so that the optical communication device can exchange data with the laser transceiver module through the laser. In order to realize the address binding between each laser transceiver module and an optical communication device after the switch is started, the functions of each module are as follows:

[0033] The transceiver controller 1042 is configured to generate an inquiry command under the control of the system controller 102, serialize the inquiry command and output it to the modulation drive module 1044, receive the address input b...

Embodiment 3

[0040] In order to enable the system controller to determine whether there is data from the optical communication device in the transceiver controller, such as image 3 The transceiver controller 1042 in the laser receiver tube 1048 is also used to save the received data after the laser receiving tube 1048 receives the data sent in the form of laser light (that is, the data sent by the optical communication device indicated by the address bound to itself) , and a data flag is set, and the data flag is used to indicate that the data from the optical communication device has been received. The system controller can know whether the transceiver controller currently has data from the optical communication device through the data flag of a transceiver controller, and when there is data, read the data and send it to the data contained in the data. The transceiver controller to which the target address is bound. After all the data in the transceiver controller is output to the syste...

Abstract

The invention discloses an exchange board, an optical communication device, and a data communication method. The exchange board comprises a system controller and at least two laser receiving and sending modules, wherein the system controller is used for sequentially judging whether data from the optical communication device currently exist in each laser receiving and sending module or not, if yes, data are read and transmitted to the laser receiving and sending modules which are bound with target addresses contained in the data, and therefore the laser receiving and sending modules which are bound with the target addresses send the data to the optical communication device indicated by the target addresses in a laser form. Each laser receiving and sending module is used for receiving and saving the data sent in the laser form, receiving the data sent by the system controller, and sending the data to the optical communication device indicated by the addresses bound with optical communication device in the laser form, wherein each laser receiving and sending module is bound with the address of the optical communication device. The exchange board, the optical communication device, and the data communication method can solve the problems of difficult wire arrangement and electromagnetic interference.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a switch, an optical communication device, and a data communication method.
