Embodiment Construction

[0045] In the following, the temperature control system of the array optical transceiver module applied to the optical switch of the present invention will be further described in detail in conjunction with the specific embodiments.

[0046] figure 1 It is a schematic diagram of a 32-port optical switch. figure 1 The numbers 1 to 32 in the optical switch represent the 32 optical transceiver modules in the optical switch. The working mode is as follows: the optical signal is first input to the optical transceiver module at the input end, and the optical signal is converted into an electrical signal by the optical receiver in the module. Then complete the signal exchange through the configured switch, and switch to an optical transceiver module at the output end, and complete the electro-optical conversion and output through the optical transmitter in the output module to realize the exchange of optical information in the optical switch. For example, when the first optical signa...

Abstract

The invention discloses an intelligent temperature control method for an array light receiving / transmitting module in an optical switch. The scheme comprises a temperature sensor, a voltage amplifying circuit, an 8-channel 16-bit D / A (digital / analogue) conversion module, an 8-channel 16-bit A / D conversion module, a central processing module, an FPGA (field programmable gate array) configuration module, a semiconductor refrigerator TEC, a keyboard, a liquid crystal display screen, a serial communication module and the like. The temperature sensor bonded with the array light receiving / transmitting module converts a temperature signal into a voltage signal which is amplified and then processed by the A / D conversion module and transmitted to the central processing module; the central processing module calculates a control quantity by using a temperature control algorithm, and the control information is converted into a control quantity of the TEC by the D / A conversion module; and the TEC realizes multi-point intelligent temperature control. The invention can implement temperature control on multiple modules at the same time in a large range and has the characteristics of real-time performance, high precision, high efficiency, large temperature control range, high extensibility and the like.
