Knowing how to test the sensitivity of a fiber optic receiver is an important skill. A fiber optic receiver provides optimal performance when the optical input power is within a certain range. But how do you test the receiver to see if it will provide optimal performance at the lowest optical input powers? One way […]

Advanced Optical Components – Optical Attenuator
What is Optical Attenuator? Optical Attenuator (or fiber optic attenuator) is a passive device that is used to reduce the power level of an optical signal. The attenuator circuit allows a known source of power to be reduced by a predetermined factor, which is usually expressed as decibels (dB). Optical attenuators are generally used in […]
