| Description
OPCA-1100E outdoor unidirectional amplifier is mainly used for the transmission of CATV television image signal, digital TV signal, and 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.
Product feature
(1) 45~ 862/ 1003 MHz bandwidth design.
(2) It is more convenient to debug because of the adjustable equalizer/attenuator, plug-in output tap and the scientific and reasonable on-line detection ports.
(3) 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.
