Bandwidth demand keeps increasing, thanks to the growing popularity of data-hungry applications such as video-on-demand and videoconferencing. Service providers therefore need to deploy faster, more reliable networks, using novel technologies such as reconfigurable optical add-drop multiplexers (ROADM) or 100G+ networks.

Optical Spectrum Analyzers to Characterize CWDM and DWDM Networks

Reducing downtime in CWDM and DWDM networks calls for an accurate measurement of optical signal-to-noise ratio (OSNR) . However, ROADM and 100+ Gbit/s networks present a new and unique challenge, as the existing OSNR measurement methods yield incorrect results.

EXFO’s in-band, Pol-Mux OSNR and in-service Pol-Mux OSNR methods are the answer to this new challenge, providing reliable measurements on a per-channel basis.

 

Truly portable solution allowing one-button operation, for easy setup and automated measurements.
