Two versions of the COSA-4055 modules
The COSA-4055 is Viavi's new generation of CWDM analyzer modules.
It scans the full wavelength range between 1260 and 1625 nm for
commissioning, upgrade, and trouble shooting of CWDM networks. The
COSA-4055 offers the functionality and speed of an optical spectrum
analyzer in a handheld form at a fraction of the price of an OSA. The
measurement result is displayed in a graphical (trace) and numerical
(table) format providing detailed information of the power level and the
wavelength of CWDM channels.
