In today’s optical cable era, optical fiber communication technology has become one of the most widely used technical methods in the field of communication. Optical fiber communication utilizes light as the information carrier and optical fibers as the transmission medium.<\/p>\n
From a macro perspective, the longer the transmission distance of optical fibers, the better. Therefore, researchers have been making new breakthroughs in the transmission distance of optical fibers.<\/p>\n
The optical receiving sensitivity, along with the optical power transmitted by the transmitter and the attenuation of the fiber optic cable line, jointly determine the relay length in the system.<\/p>\n
1) Both an excessively low input fiber optic power to the optical transmitter and an excessively high input fiber optic power to the receiver can affect the transmission distance of the optical communication system.<\/p>\n
2) Impact of power loss: Due to the limited transmission power of the optical transmitter and the internal noise of the optical receiver, sufficient signal optical power output is necessary for normal reception. Coupled with the transmission loss inherent to optical fibers, the transmission distance of the system is inevitably limited, which is referred to as power loss limitation.<\/p>\n
3) Chromatic dispersion: In terms of chromatic dispersion, greater dispersion leads to more severe waveform distortion. As the transmission distance increases, waveform distortion becomes more pronounced. In digital communication systems, waveform distortion can cause inter-symbol interference, reduce optical receiving sensitivity, and affect the system’s relay distance.<\/p>","protected":false},"excerpt":{"rendered":"
