DWDM Wavelength Monitoring Module

Introduction

In case the fiber being monitored is carrying many multiplexed frequencies using Dense Wavelength Division Multiplexing (DWDM) technology then these multiplexed wavelengths will need to be demultiplexed into individual wavelengths for further processing to derive the content from each wavelength. Traditionally, determining the network content of all 96 wavelengths within the DWDM C-Band grid required several equipment’s and could be a lengthy trial and error process.

The Shoghi is the first purpose-built full-duplex DWDM Wavelength Monitoring solution capable of discovering which DWDM C-Band wavelengths are in use and reporting the details of the traffic carried over each of these wavelengths, without any previous knowledge of the network's provisioning. This includes identification of signalling speeds from 2.5G to 100G and transport technologies including OTN, SONET/SDH and native Ethernet. The details of the discovered DWDM network can be used to direct individual wavelengths to the desired network monitoring tool(s).
