Product Description
Performance Characteristics
1.Full CPU control the machine work, LCD displays the parameters, such as supply voltage. Control downlink input optical power, attenuation, equilibrium, uplink output optical power and laser current etc. variables, operation is convenient and intuitive, and performance is stable. Reduce a large number of optional accessories.
2.Excellent AGC characteristic, when the input optical power range is -9~+2dBm, the output level, CTB and CSO basically unchanged.
3.Optimizing circuit design, SMT production process, optimizing the whole signal path, made the photoelectronic signal transmit more stable, RF linear index higher.
4.Professional RF electrical adjustable attenuation chip, RF electrical adjustable equilibrium circuit, good linearity, high precision.
5.GaAs amplifier device, power doubler output, high gain and low distortion.
6.The return path adopts professional RF electrical adjustable attenuation chip instead of the three-state switch.
.Reserved the data communication interface, can connect the network management responder, access to the network management system, the variables can be remote controlled by the network management.
8.The shell adopts embedded modular design; equipment maintenance, replacement, and debugging are convenient.
