MODEL:8912-GK

Features:

※ 4-ports output, level of esch port is 108dBμV.

※ Import ORTEL or PHILIPS optical module used for optical receiving, import GI and PHILIPS GaAs

※ module used for RF amplification, to guarantee good performance and high-reliablity of the whole set.

※ Working band width is 860MHz, the function of fiber optic return can be expanded, to meet the reqirements

※ of CATV system to carry out the function for service.

※ The whole set use switching power supply, less tempreture rise, adapt to a wide voltage range, high-reliablity,
220VAC and 60VAC optional.

※ Have the display circuit of optical power alarm, the green LED light on when receiving in -5~2dBm,
ease of maintenance.
