[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.[Specifications] SC/APC singlemode fixed fiber optic attenuator 10dB,Polarization dependent loss ≤0.2dB and return loss ≥60dB[Characteristic] High attenuation accuracy, low added loss and good stability[Applications] Fiber optic CATV, fiber optic communication systems, high power optical device measurement[Function] Used for attenuation of input optical power, avoiding damage to receiving fiber optic equipment due to excessive input optical power
