Introduction to LC UPC Attenuator
LC UPC Attenuators are devices to reduce the optical fiber power by a certain level within the fiber optic network. LC/UPC Attenuators are usually used when the signal arriving at the receiver is too strong and hence may overpower the receiving elements. This may occur because of a mismatch between the transmitters/receivers (transceivers, media converters), or because the media converters are designed for a much longer distance than for which they are being used. Sometimes LC fiber attenuators are also used for stress testing a network link by incrementally reducing the signal strength (increasing the dB attenuation) until the optical link fails, thus determining the signal’s existing safety margin.
