FC FixedFiber Optic Attenuator — UPC & APC, Threaded Coupling
FC fixed fiber optic attenuator with threaded screw-on coupling for secure, vibration-resistant connections. Available in UPC and APC polish types with fixed attenuation values from 1dB to 25dB. Ideal for telecom, test equipment, and industrial fiber applications requiring stable attenuation.
Technical Specifications
Engineered For Performance
Threaded Coupling Security
Screw-on threaded mechanism locks the attenuator firmly in place, preventing accidental disconnection in vibration-prone telecom rooms, test benches, and industrial environments.
Precision Attenuation Control
Factory-calibrated fixed attenuation from 1dB to 25dB with ±1.0dB accuracy provides reliable, drift-free signal level reduction across the full operating temperature range.
Test Equipment Compatible
FC interface is the standard connector on OTDR, optical power meters, and light sources, making this attenuator ideal for laboratory calibration and field testing setups.
Extended Temperature Range
Operating range of -40 to +85 degrees C supports deployment in outdoor cabinets, rooftop equipment, and uncontrolled environments without attenuation drift.
Typical Applications
Telecom Equipment Rooms
Optical power adjustment at OLT line cards, DWDM transponders, and EDFA outputs in central office and cable landing station equipment racks.
Test & Measurement
Calibrated attenuation for OTDR dynamic range testing, receiver sensitivity measurements, and optical link budget verification with FC-terminated test instruments.
Industrial Fiber Networks
Signal level management in factory automation, oil and gas SCADA, and utility monitoring networks where threaded connections resist mechanical vibration.
