FC PC Attenuator
Optical fiber attenuator is a passive optical device, mainly used to reduce the optical power of the optical signal, to prevent the optical power reaching the optical receiver from exceeding its carrying range and causing signal distortion; there is also a case in the optical fiber of the multi-wavelength channel In the system, the optical signal power of each channel needs to be roughly the same, so the optical fiber attenuator is used to balance the optical power of each channel. This tutorial will give a detailed introduction to the types and working principles of optical fiber attenuators.
Good repeatability and interchangeability
Small attenuation change with wavelength
Low additional loss
Fiber optic communication network
Fiber data network
Fiber CATV network
Fiber test system
Measurement of high power optical devices
With the development of the optical communication industry and the improvement of the level of manufacturing technology, the loss of optical fiber devices such as optical cables and connectors is continuously reduced, which is less than the designed attenuation. This may cause the optical receiver to receive a large optical power that exceeds it. Tolerable range, saturation and distortion appear. Therefore, in order to reduce the signal received by the optical receiver, an optical attenuator is needed to control the optical power within a certain range.
