Optical fiber repeater is a mobile communication repeater that uses optical fiber as the transmission medium, but the optical fiber itself also has signal loss during transmission, mainly due to the loss caused by connection and length
The more optical fibers are connected, the longer the length is, the greater the loss is, so the output power of the optical fiber repeater also follows the loss in actual use. The traditional improvement method is to minimize the loss of optical fiber link transmission. The traditional optical fiber repeater After installation, its rated output power is correspondingly lost due to the loss of optical fiber transmission, and the actual output power is less than the rated output power

The invention provides a fiber optic repeater power compensation method which includes the following steps: an optical receiver receives an optical signal from optical fiber; an optical power detection device receives the optical signal and converts the optical signal into optical power value; a CPU samples the optical power value and compares the optical power value with reference optical power value; if optical path loss is detected; CPU controls a power amplification device to increase the input power inputted to an optical transmitter. The fiber optic repeater power compensation method increases the output power of the fiber optic repeater to compensate power consumed by optical fiber, so as to realize constant power output on the premise that the optical fiber transmission loss is reduced.
Description
technical field [0001] The invention relates to the communication field, in particular to a power compensation method for an optical fiber repeater. Background technique [0002] With the continuous development of wireless communication, the requirements for signal transmission are getting higher and higher, and the transmission medium is required to have the following properties: long transmission distance, large transmission bandwidth, small transmission loss, and strong anti-interference. Optical fiber has the above advantages, so it is widely used in various communication transmissions. Optical fiber repeater is a mobile communication repeater that uses optical fiber as the transmission medium, but the optical fiber itself also has signal loss during transmission, mainly due to the loss caused by connection and length. The more optical fibers are connected, the longer the length is, the greater the loss is, so the output power of the optical fiber repeater also follows ...
