Introduction
Assembled with forward optic receiving main-board and reverse transmitting mounting part(or reserve), equipped with American well-known optic receiving parts as EO, ORTEL or PHTEROLA brands, and low noise microwave push-pull and imported PHILIPS, MOTOROLA low noise pre-position module and 2 power doubler modules for signal amplification at front stage, it ensures high-parameter signal output. With built-in equalizer, attenuator, and optic power indication, reliable switching power supply and rigorous anti-shock system, it ensures long time safe and sound operation.
Imported well-known optic transmission module as made by Japanese Mitsubishi Co. is used as reverse optic transmission mounting part for setting up the CATV reverse transmission system of images and language, etc.
Features
l With modularized inserted optic receiving PCB, it is suitable for different PIN.
l GaAs pre-positioned amplifier module gives super low noise and low optic power receiving.
l Built-in 6-band optic power meter accurately displays input power.
l Large power at 2 terminals of downlink signal, good parameters output, adjustable power level.
l With protection circuit both for power supply and control circuit, supported by low power consumption design, it enables operation more stable and reliable.
l With independent feeder interface, it enables power supply more practical and easy.
