| Description
OPCA-1100KL field trunk bi-directional amplifier is mainly used for bi-directional trunk transmission of CATV television image signal, digital TV signal, telephone voice signals and data (or compressed data) signal. Advanced and mature circuits, scientific and reasonable process structures and high quality materials, ensure the excellent performance. It is the best choice for building large or middle-sized CATV bi-directional transmission network.
Product feature
(1) 1000MHz bandwidth design.
(2) The pre-amp of forward path adopts GaAs MMIC amplify module, output stage adopts the latest imported, high index, power double module, achieve the high output level, low distortion and high signal to noise ratio.
(3) It is more convenient to debug because of the plug-in duplex filter, equalizer, attenuator, output splitter and the scientific and reasonable on-line detection ports. (4) The equipment can long time continuous work steadily under outdoor bad environmental condition. Because of the aluminum waterproof housing, high reliability switching power supply and strict lightning protection system.
