Tempo OWS202 - Optical Wavelength Splitter, 1490nm / 1577nm

The Optical Wavelength Splitter (OWS200) is used to separate the various wavelengths that may be present in a NGPON2 system to measure each specific signal level. 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 marginal influence on the measurements.

Currently the OWS200 supports 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.

• OWS201 - 1490 / 1570nm
• OWS202 - 1490 / 1577nm

How the OWS200 is used

1. Connect the fiber under 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, i.e. for 1577nm select the 1550nm calibration.

*Make sure to clean and inspect all connectors and bulkheads prior to connection.
