ST/UPC Fixed Fiber Optic Attenuators

These ST/UPC Fixed Fiber Optic Attenuators are designed to reduce excessive optical signal power and help maintain proper receiver performance in singlemode fiber networks. Available in 5 dB, 10 dB, 15 dB, and 20 dB attenuation levels, they support 1310 nm and 1550 nm operating wavelengths, feature UPC polished interfaces, and provide consistent fixed attenuation for use in telecom systems, fiber distribution networks, testing environments, and other optical installations where signal levels need to be controlled.
