• Separate wavelengths present in GPON, XG PON, and NGPON2 to measure optical power at each wavelength independent of other network signals
• Wavelengths: 1550nm and 1577nm
• Eliminates the need for expensive DWDM power meters – enables standard optical power meters to measure each signal
• High accuracy to measure specific channel wavelengths
• SC/APC connections

The Optical Wavelength Splitter (OWS200 series) is used to separate the various wavelengths that may be present in GPON, XG PON, and NGPON2 networks to measure the optical power at each wavelength independent of other network signals. A standard optical power meter such as the OPM510 or OPM210 can then be used to measure each signal without the need to purchase a costly DWDM OPM. The optical loss of the OWS200 is typically less than 0.1dB and as a result, has a marginal influence on the measurements. The typical loss of the OWS204 is 0.5dB.

All models of the OWS200 support two individual wavelengths but systems with four and eight are also possible. The user selects the model that supports the system wavelengths that they intend to measure, which determines the model of OWS200.

1. Connect the fiber under the test to the input port.

2. Connect a standard power meter to each of the output ports.

3. Set the power meter to the closest possible calibrated wavelength for each measured signal.
