optical receiver

CATV optical receiver feature: Rational structure,High integration Convenience installation and debugging Output return optical receiver is used for forward return receive of TV image signal Digital TV signal telephone sound signal and data signal output optical receiver Advanced automatic power control circuit High-performance multi-band-pass filter Effectively improves signal to noise ratio of reverse channel indicators RF output level constantly Enhances reliability for uplink of cable HFC network Four independent optical receive units are setup in 19 inches 1U standard rack Each unit receives and amplifiers independently Adjustable output level with independent monitoring port E-O low-noise high-sensitivity detector Low receiving optical power and high NPR Low-noise microwave push-pull circuit Low noise figure, but also high output level and good nonlinear index High-performance band-pass filter Effectively control network pool noise which is under 5 to 25MHz band Increases uplink NPR indicators Advanced automatic power control circuit, when input optical power change range of 0 to 8dBm
