1 Introducing the FOT-5200
CWDM Analyzer
The FOT-5200 CWDM Analyzer is designed to measure and mark
wavelengths in order to measure the exact power independently for each
coarse wavelength division multilplexing (CWDM) channel. This
instrument is portable and made to be appropriate to the outside
environment.
When using a broadband powermeter, only the total optical power of the
combined CWDM channels can be measured. When several wavelengths
are sent at once, the exact value of each wavelength cannot be measured.
Thus for CWDM, which functions over several wavelengths, a device that
can distinguish the wavelengths must be used.
The FOT-5200 is developed to measure exact power and is adaptable to
the various network conditions. It is especially suitable for outer
environments and is compact, therefore easy to carry.
