how to accurately measure optical signal-to-noise ratio (OSNR) on a per-channel
WELLZiON’s Spectral Testing provides customizable CWDM/DWDM testing, in-band OSNR, light source, EDFA, fiber probe, auto testing, and more.

Choose spectral testing that best suits your needs
This last level of optical source integration involves simulating in laboratory the behavior of the transceivers in an optical
network that replicates the topology of real networks: long fiber spans, amplifiers, maybe some reconfigurable add drop
multiplexers (ROADMs), a large number of channels, etc. As such, the spectral measurements carried out on optical
systems in laboratories, usually by verification groups, are very similar to those made in the field, on actual networks.
The relevant tests are:
- Channel central wavelength
- Channel power
- Optical signal-to-noise ratio (OSNR)
