Fiber optic attenuators are devices to reduce the optical fiber power by a certain level within the fiber optic network. Fiber 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 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. This LC APC fiber attenuator contains doped fiber suitable for both 1310nm and 1550nm operation. Fixed attenuation values are available in 1dB increments from 1 to 25dB. We have a mature attenuator production process, and can fully meet customer needs. Each attenuator is shipped with a test report that makes it easy for customers to check the optical performance quickly
