These reasonably priced modules offer the funcionality and speed of an OSA in a handheld form - for metro/access links and CWDM systems.
The COSA (compact optical spectrum analyzer) is the smallest CWDM OSA on the market. Compared to conventional OSA modules, it has the same functionality and speed but is cheaper. This module is used with the MTS-2000 or MTS-4000 platform.
For service providers, the COSA is the ideal testing unit for installation, maintenance, and the upgrade of metro/access networks and CWDM systems. It measures the power level and wavelengths of CWDM channels and displays the complete spectrum.
