Description

Technical Field

[0001] The present invention relates to the field of optical fiber transmission technology, and in particular to a wavelength division multiplexing optical fiber transmission system. Background Art

[0002] Wavelength division multiplexing is a technology that combines two or more optical carrier signals of different wavelengths through a multiplexer at the transmitting end and couples them to the same optical fiber of the optical line for transmission. At the receiving end, the optical carriers of various wavelengths are separated by a demultiplexer, and then further processed by the optical receiver to restore the original signal. This technology of simultaneously transmitting two or more optical signals of different wavelengths in the same optical fiber is called wavelength division multiplexing. Fiber optic transmission is data and signal transmission using optical fiber as the medium. Optical fiber can not only be used to transmit analog and digital signals, but also meet the needs of video transmission.

[0003] At present, the bandwidth capacity of optical fiber transmission is limited, which makes system upgrades difficult and costly. When processed through comb filters, the processing efficiency is low and it is difficult to process and convert quickly.

[0004] When the optical fiber transmission system is transmitting signals, the camera is easily interfered by strong electromagnetic radiation, which causes the monitoring screen to be interrupted and the audio monitoring cannot be performed at the same time. It is difficult to meet the remote online monitoring needs of the system. If the system fails, the remote monitoring will stop, affecting the use effect of the optical fiber transmission system.

[0005] Optical fiber lines on land are usually laid underground or overhead. Environmental changes in the northeast region in winter cause a large temperature difference between day and night, which has a greater impact on the loss of overhead optical fiber. When there are engineering operations at the underground site, it will also affect the quality of the optical fiber line. These will affect the transmission performance of the system, and if a fault occurs during optical fiber transmission, it is easy to cause power outages and cause system crashes.

[0006] Therefore, a new type of wavelength division multiplexing optical fiber transmission system is proposed to solve the above problems. Summary of the invention

[0007] The main purpose of the present invention is to provide a wavelength division multiplexing optical fiber transmission system to solve the problems raised in the above background.

[0014] The optical fiber protection module is used to separate the optical lines from each other through a wavelength division device. When one of the optical fiber lines fails, detection can be achieved by simply plugging and unplugging the failed optical fiber line. At the same time, the solar thermal power generation module can store electricity for the optical fiber transmission system when it is short-circuited, thereby obtaining a power-off-proof optical fiber transmission system.
