Product Description

FC / APC Optical Fiber Attenuator For Telecom Networks / Variable attenuator

Fiber optic attenuators FC/APC are designed to give accurate attenuation over a wide range of wavelengths. The plug type configuration allows them to be used directly on the end of a patch cord, which in turn can insert directly into an adaptor.


Optical attenuator FC/APC are capable of withstanding over 1W of high power light exposure for extended periods of time, making them well-suited to EDFA and other high-power applications. Low Polarization Dependent Loss (PDL) and a stable and independent wavelength distribution makes them ideal for DWDM.


Variable fiber optic attenuators are hand-held devices that are used for testing and measurement, or equalizing the power between different signals. They can offer a range of attenuation values with flexible adjustment. Because variable attenuators work by directly blocking the beam, they are polarization insensitive. Like fixed attenuators, variable optic attenuators are also offered with singlemode, multimode, or polarization maintaining fibers.
