Bi-Directional Mini-Node (iTRVR-B)

Data Sheet

The Optilab iTRVR-B is a bi-directional analog Optical Network Unit (ONU) designed for Deep Fiber and RFoG applications.

Product Overview

The Optilab iTRVR-B is a bi-directional analog Optical Network Unit (ONU) designed for Deep Fiber and RFoG applications. Available in Burst Mode or CW, the iTRVR-B uses Wavelength Division Multiplexing (WDM) technology to combine 1550 nm forward-path signals and 1310 nm or CWDM return-path signals on a single optical port. The iTRVR-B can provide the HD video and QAM data bandwidth capacity of a traditional HFC optical node, but at a fraction of the cost. The return-path bandwidth capacity of the RFoG systems can be increased greatly by using return-path lasers from 7 different CWDM wavelengths. Additionally, this versatile, compact mini-node is well-suited for a node splitting solution of a deep fiber system that enhances an existing HFC infrastructure.
