Wavelength Division Multiplexing (WDM) is a fiber-optic transmission technique that enables the use of multiple light wavelengths (or colors) to send data over the same fiber. Dense WDM (DWDM) uses tighter wavelength spacing to fit more channels onto a single fiber.

Monitoring DWDM networks is complex and expensive. Determining the signaling and network content of each of the DWDM C-Band grid’s 96 wavelengths requires complex monitoring equipment and the traffic discovery process can be a lengthy trial and error process.

The NetQuest I-9196 is a purpose-built full-duplex DWDM Wavelength Monitoring solution that leverages the latest technology innovations to automatically discover and identify the wavelengths and multiplexing techniques being used along with the traffic types for each of the Lambdas transported.

The NetQuest I-9196 auto discovers and intercepts 2.5 Gbps through 100 Gbps services including Ethernet over DWDM, GFP, PoS, OTN, SONET/SDH and channelized services. The I-9196 automates the discovery of the content of a DWDM optical network to enable instant access to individual wavelengths of interest without knowledge of the network’s provisioning. The I-9196 directs individual wavelengths to the targeted network monitoring tools via its colorless wavelength and speed agnostic internal switching fabric.
