Usage Tips:Product features: Use high-quality E-O photoelectric conversion and gallium arsenide amplification integrated light receiving module.Fully automatic optical AGC control, input optical power -7 ~ 15dBm output level unchanged, CTB, CSO basically unchanged. RF channel full gallium arsenide low noise amplifier device. Reliability: The average trouble-free working time is higher than 40, 000 hours. Low power consumption design, using high-efficiency switching power supply, specially designed for CATV, to ensure high reliability and high stability of the power supply. The power consumption of the whole machine is less than 5W, which will greatly reduce the power consumption when used on a large scale.Built-in Lightning-Pattern protection device (TVS ient suppression diode), the Lightning-Pattern protection system is strict to ensure the safe operation of the equipment. Adopt high-quality shell with good heat dissipation function.220V power supply, using external power supply, easy to maintain.The components are clean and tidy, the internal and external craftsmanship is good, and the components of the whole machine are not loosened, which conforms to the standard.
