Fiber Optic Node CATV

Summary
SR1004 outdoor an optical node is two-way optical joint equipment that is based on several years research experience of CATV HFC fiber transmitting equipment, specifically developed for the HFC structure two-way metropolitan area broadband network. This Fiber Optic Node CATV is a great choice to construct the high-quality bidirectional HFC metropolitan area broadband network.
Characteristics
1.Full CPU control the machine work, LCD displays the parameters, such as the input/output level. Variable control operation is convenient and intuitive, and performance is stable. Reduced a large number of optional accessories.
2.This Fiber Optic Node CATV SR1004 adopts advanced optical AGC technology, optical AGC control range: +2dBm ~ -9/-8/-7dBm adjustable.
3.Two-channel optical signal receiver backup each other, can set automatic switching condition arbitrarily, also can be set to manual switching.
4.Optimizing circuit design, SMT production process, optimizing the whole signal path, made the photoelectronic signal transmit more stable, RF linear index higher.
5.Professional RF electrical adjustable attenuation chip, RF electrical adjustable equilibrium circuit, good linearity, high precision.
6.GaAs amplifier device, power doubler output, high gain and low distortion.
7.The return path adopts professional RF electrical adjustable attenuation chip instead of the three-state switch.
