FTTx Wavelength Selective Adapter Cap

Allows any NOYES Optical Power Meter (OPM), including all OPM1, OPM4, and OPM5 models, to measure downstream signal power on FTTx networks carrying both 1490 nm and 1550 nm signals.

Adapter Cap Operation

To operate, the user simply sets the adapter cap and power meter to the same wavelength, either 1490 or 1550 nm. A third ‘unfiltered’ adapter cap position is provided to measure optical power at 1310 nm or any other wavelength supported by the power meter. The new adapter cap is compatible with SC or angled SC connectors.
