SC Single Mode Fiber Attenuation Structure
Precision engineering, international standard structure with metal bayonet mount, black dust cap, with mounting holes for screws and tabs, single-channel, blue housing. If need APC fiber, should use green housing, if multimode fiber, will use beige, aqua or purple housing.
All single mode fiber atteuation made by yingda are telecom quality, value can be 1dB to 20dB, 1dB gap, and fixed attenuation value. It is high precise, for example 5dB attenuation accuracy is ±0.5dB, with low loss and good repeatability.
This SC UPC attenuator both ends are SC female connectors, similar to a coupler, allowing direct insertion of SC connectors. It features low insertion loss and good stability.
