Transmission distance and attenuation of optical modules
Long distance transmission refers to distances greater than or equal to 30km. The commonly used wavelengths in optical fibers are 850nm, 1310nm, and 1550nm, which have longer waveforms and therefore have relatively less attenuation. So, what is the relationship between wavelength and transmission distance? Is wavelength a factor affecting the transmission distance of optical. Link budget refers to the calculation of all gains and attenuations in a communication system, including those from the transmitter, communication links, propagation environment, and receiver. It is typically used to estimate the maximum distance over which a signal can be successfully transmitted. According to the different transmission distances of optical modules, they can be divided into three types: short-distance optical module s, medium-distance optical modules, and long-distance optical modules. Among them, long-distance optical modules refer to optical modules with a transmission. The transmission distance of optical transceiver modules is divided into short distance, medium distance, and long distance.
