LC/APC Fixed Fiber Optic Attenuators

These LC/APC Fixed Fiber Optic Attenuators are designed to reduce optical signal power in singlemode fiber networks where excessive input power may overload receiving equipment. Available in 5 dB, 10 dB, 15 dB, and 20 dB attenuation levels, they support 1310 nm and 1550 nm operating wavelengths, feature APC polish with a return loss of at least 65 dB, and provide wavelength-independent performance for reliable use in fiber links, test environments, telecom systems, and other optical network applications.
