ZBL-ON-300AC RFoG Mini Optical Node

ZBL-ON -300AC Mini Optical Nodes with burst mode is a bi-directional optical node by one fiber

 transmission that combine the superior proven technologies of both the RF amplifier and optical 

components. In the forward receiver path, the node contains an Automatic Gain Control(AGC) circuit to maintain the output level over an input optical power of -6~+2dBm. In the return path.

 Automatic Optical Control(AOC) circuit is designed to reduce the return noise effectively, to lower the 

power consumption and prolong the working life. It is compact in size, high performance and high reliability, 

and can provide the full comptement of functions required by FTTB,FTTH networks.
