Attenuation In Single Mode Fiber Details
The FC APC attenuator uses a brand-new metal material and features either a one-piece or separate component structure. After passing factory testing, each connector is fitted with a dust cap.
This fixed optical attenuator can only attenuate a fixed optical power, such as 3dB, 5dB, 15dB, 20dB, 25dB, etc. It is an attenuator designed for FC connectors, with a female-to-female connection. It is secured by screwing it in after insertion.
All Yingda fiber optic attenuators built-in single-mode attenuating fibers and are tested at 1310nm and 1550nm wavelengths before shipment. They utilize high-quality ceramic ferrules to secure the fibers, ensuring high attenuation accuracy and excellent stability, with a mating cycle of up to 1000 times. They are widely used in optical transceivers, optical modules, distribution frames (ODF), optical power meters, test equipment, medical equipment, and other products.
