Product Overview

The Optilab iTRVR-G is a bi-directional analog Optical Network Unit (ONU) designed for combining GEPONbased systems with RFoG applications. The iTRVR-G contains a full-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 nm -1610 nm in return-path, can be added to with the GEPON ONU signals, which are 1490 nm downstream and 1310 nm upstream. The iTRVR-G can provide the HD video and QAM-based return data bandwidth as in a conventional HFC optical node, and 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 lasers with 3 different CWDM wavelengths. All contained within a compact, versatile mini-node, the iTRVR-G is the most cost-effective solution available. Contact Optilab for more
