The QAMnet iTRVR-G is a bi-directional analog Optical Network Unit (ONU) designed for combining GEPON-based systems with RFoG applications.
Product Overview
The QAMnet iTRVR-G is a bi-directional analog Optical Network Unit (ONU) designed for combining GEPON-based systems with RFoG applications. The iTRVR-G contains a fully function burst mode RFoG mini-node and an internal multiplexer for combining external GEPON signals. With advanced Wavelength Division Multiplexing (WDM) technology, optical wavelengths from the analog ONU, which are 1550 nm in forward-path and 1570-1610nm in return-path, can be added to with the GEPON ONU signals, which are 1490 nm down-stream and 1310 nm upstream.
With a forward 1550nm forward-path receiver and a return-path CWDM DFB laser, the iTRVR-G can provide the HD video and QAM-based return data bandwidth as in a conventional HFC optical node. With its fast Burst Mode operation,the iTRVR-G Mini-Node is designed for next generation FTTH applications such as RF over Glass (RFoG) or Cable Passive Optical Networks (Cable PON). The iTRVR-G is a very versatile and powerful mini-node. It can be used for enhancing GEPON transmission in HFC, Deep Fiber and RFoG networks. The return path bandwidth capacity of the RFoG systems can be increased by a factor of 3, by using return path laser with from 3 different CWDM wavelengths.
