LC FixedFiber Optic Attenuator — UPC & APC, 1-25dB Inline
LC inline fixed fiber optic attenuator with male-female plug-in design. Available in UPC and APC polish types with attenuation values from 1dB to 25dB. 1.25mm zirconia ceramic ferrule for precise optical power level adjustment in single mode fiber systems.
Technical Specifications
Engineered For Performance
Compact Inline Design
Male-female plug-in form factor connects directly into LC adapter panels or equipment ports, adding precise attenuation without additional cables or bulky external devices.
Wide Attenuation Range
Available in fixed values from 1dB to 25dB, allowing engineers to select the exact attenuation needed for signal level balancing across diverse network configurations.
Dual Polish Options
Offered in both UPC (≥45dB return loss) and APC (≥60dB return loss) polish types to match existing network infrastructure and minimize back-reflection in sensitive systems.
High Power Handling
Standard 500mW and optional 1000mW high-power variants handle elevated optical power levels in amplified DWDM and CATV systems without performance degradation.
Typical Applications
Signal Level Balancing
Reduces optical power to optimal receiver sensitivity range in FTTH, PON, and metro networks where short fiber runs deliver excess signal strength.
Receiver Overload Prevention
Protects sensitive photodetectors and optical receivers from saturation caused by high-power transmitters or optical amplifiers in DWDM systems.
Test & Measurement
Provides calibrated attenuation for optical power meter testing, OTDR calibration, and link budget verification in laboratory and field environments.
