Attenuators]Attenuators are a type of optical passive device in fiber optics that can attenuate fiber optic signals, calibrate and correct optical instruments, and debug optical power performance to stabilize and maintain the optical power level in the link without altering the original transmission wave ^^ SpecificationsSC/APC singlemode fixed fiber optic attenuator 5 dB, return loss 60 dB ^^ CharacteristicHigh attenuation accuracy, low added loss and good stability ^^ FunctionUsed for attenuation of input optical power, avoiding damage to receiving fiber optic equipment due to excessive input optical power ^^ ApplicationsFiber optic CATV, fiber optic communication systems, high power optical device measurement
