Product Overview

The QAMnet nTRVR-B is a bi-directional outdoor optical node designed for deep fiber implementation in HFC networks. Using the proven Wavelength Division Multiplexing (WDM) technology, a 1550 nm receiver and a 1310 nm transmitter are combined into a common optical input/output port. The nTRVR-B is a versatile, compact, low cost transceiver optical node. With a standard HFC configuration of forward receiver and reverse transmitter, the iTRVR can provide the HD video and QAM data bandwidth capacity of a traditional HFC optical node, but at a small fraction of the cost.

Along with other QAMnet products, the nTRVR-B is an ideal deep fiber solution for delivering Switch Digital Broadcasting (SDB), as well as high-speed QAM data services over existing HFC infrastructure. Using a single optical input/output design, nTRVR-B can be easily integrated ino the next generation HFC networks architectures, such as RF over Glass (RFoG) or Cable Passive Optical Networks (Cable PON).
