BTF N/B/R OPTICAL MULTIPATH FILTER		print pdf version

Application Universal optical filter utilized for decoupling of wavelength bands for Broadcast - (BC), Narrowcast - (NC) und Return path - (R) signals Distribution of optical signals in DWDM CATV networks Features Transmission of BC signals with minimum loss in DWDM networks Low insertion loss for all 3bands Extension of networks with bands for NC and R are not effecting the BC path Two versions available for different signal directions: Headend (HE) and Hub (HUB 19“/1HE – chassis with E2000- adaptors
