Abstract

The invention discloses an automatic photoelectric signal conversion method. The method comprises the specific steps that pulse command analysis is carried out during signal transmission; whether theconfiguration is conducted or not is selected; if the configuration is selected, the configuration selection is turned on, and the hardware selection is turned off; if the configuration is not selected, the configuration selection is turned off, and the hardware selection is turned on; after the configuration is selected, the mode type judgment is carried out; if the user inputs an instruction 00,a 2M PDH electric signal is output; if the user inputs an instruction 01, a 2M PDH optical signal is output; when configuration is not selected, a 2M PDH electrical signal is output. According to theinvention, when a user needs to use 2M PDH optical signals, coding conversion is carried out to output the 2M PDH optical signal, and when the 2M PDH electric signal needs to be used, the 2M PDH electric signal is output by default. Accordingly, the requirement that a user not only needs to use the 2M / PDH optical signal but also needs to use the 2M PDH electric signal is met, two discs for powersupply and light port are not required to be configured, and the cost and power consumption are saved.

Description

technical field [0001] The invention relates to the technical field of photoelectric signal conversion, in particular to a photoelectric signal automatic conversion method. Background technique [0002] In the past, 2M PDH in the transmission network was transmitted through cables, and HDB3 code conversion was adopted to output 2M PDH electrical signals. The transmission distance of this transmission method is short, and it is easily disturbed by the environment, so it is only suitable for the application in the telecommunications room with good environmental conditions. However, in the originally established power control system, due to poor environmental conditions, strong electromagnetic interference, and long transmission distance, it is not suitable to use 2M PDH electrical signal transmission for modern power control signal systems. In current network applications, optical fiber transmission has become the main transmission means of modern communication networks. In a...
