FC/APCFiber Optic Pigtail — High Return Loss, Threaded Coupling
FC/APC single mode fiber optic pigtail combining threaded screw-type coupling with 8-degree angled polish for maximum return loss of 60dB or greater. 0.9mm tight buffer with G.652D 9/125μm fiber. Green connector body for APC identification. Engineered for analog CATV, high-sensitivity optical systems, and precision measurement applications.
Technical Specifications
Engineered For Performance
Ultimate Back-Reflection Suppression
Combines FC threaded coupling stability with APC 8-degree angle polish for the highest return loss performance, eliminating optical reflections in sensitive analog systems.
CATV & RF-over-Fiber Ready
≥60dB return loss meets the stringent requirements of analog CATV head-end equipment, RF-over-fiber systems, and wavelength-sensitive DWDM applications.
Secure Threaded Connection
Screw-type coupling prevents accidental disconnection in vibrating equipment racks and ensures stable optical alignment during continuous operation.
Precision Factory Polish
Every FC/APC pigtail undergoes automated interferometric inspection to verify angled end-face geometry and surface quality before shipping.
Typical Applications
Analog CATV Networks
FC/APC pigtails at CATV head-end transmitters, EDFAs, and receivers where back-reflections cause composite second order (CSO) and composite triple beat (CTB) distortion.
High-Sensitivity Optical Systems
Precision fiber termination for optical sensors, interferometric measurement systems, and coherent detection receivers requiring minimal back-reflection.
DWDM & Amplifier Splicing
FC/APC pigtail termination on DWDM multiplexers, optical amplifiers, and dispersion compensating modules in long-haul telecom transmission systems.
