MOR-RFoG-A RFoG Node

Query


MOR-RFoG-A is a 1 GHz compact size two-way node for DOCSIS FTTH architecture. It provides excellent forward and reverse path performance combined with high reliability and a user-friendly layout. It provides excellent forward and reverse path performance combined with high reliability and a user-friendly layout. There is optical AGC function in forward path to ensure same RF output level in every home. The return transmitter adopts burst mode (turn on the laser by return signal) to greatly reduce return fibers.

  

Features

  l Supports 1 GHz RF pass band

  l One fiber WDM for forward and return path

  l AGC optical input range of - 10 to + 2 dBm

  l 31 dBmV RF output level

  l RF test points for forward and reverse path

  l Laser status switch point for installation easily

  l LED indicators for optical input, output and power

  l Reverse laser OMI adjustment

  l Low power consumption
