Single Mode Attenuator 4dB SM 754-1104-4SE00 AFOP Fixed Attenuators control the optical power in a fiber. They are often combined with an active system component to maintain a desired optical power on a network even if the power of the input signal is changing. AFOP’s Fixed Optical Attenuators reduce the optical power within a given optical path without interfering or reducing the optical signal quality. Typically, this function is embedded in an optical connector or adapter element to simplify optical network installation. We utilize attenuating fiber that reduces power while preserving performance characteristics, including optical signal quality.Applications• DWDM • CWDM • Test Equipment • CATV Systems • Point to Point Systems • TelecommunicationsFeatures• Standard Fixed Attenuation Value 4 dB • Precision Polishing for Reduced Back Reflection • Low Input Polarization Sensitivity • Telcorida GR-910 Qualified>>>Click here to view our other listings.
