Product Description
E-8130 outdoor two-way trunk amplifier is mainly used for two-way trunk transmission of CATV video signal, digital TV signal, telephone sound signal and data (or compressed data) signal. With sophisticated advanced circuit design, scientific and reasonable technology and structure, careful materials selection, and built-in high performance ATCI automatic temperature compensation and control circuit, it ensures excellent performance and parameters of the finished product. It is the first choice product for large and medium sized CATV two-way transmission network.
With imported PHILIPS or Motorola low noise push-pull amplifier module or NEC GaAs amplifier module for forward path, it enjoys high output level, good nonlinear parameters; With PHILIPS or Motorola reverse special amplifier module for return path, it enjoys small distortion, high S/N ratio.
Inserted diplex filter, inserted fixed (or adjustable) equalizer, fixed (or adjustable) attenuator, inserted output tap, are scientifically and reasonably laid out at test port, allowing easier engineering debugging.
Al casting waterproof casing, highly reliable switching power supply, rigorous anti-thunder system, ensure the product's constant stable operation under outdoor abominable condition.
