Tempo OWS202 Optical Wavelength Splitter - 1490nm & 1577nm, SC/APC

The Optical Wavelength Splitter (OWS200, OWS201, OWS202, OWS203) is used to separate the various wavelengths that may be present in GPON, 10G PON, XGPON, and NGPON2 networks 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 for 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. Currently, 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 they intend to measure, which determines the model of OWS200.

The OWS202 allows the technician to measure 1490nm and 1577nm in overlaid 1G and 10G networks without influence from the adjacent wavelength.

DWDM and CWDM networks increase the amount of data that can be transmitted over a given fiber by simultaneously transmitting two or more wavelengths on one fiber. The ITU grid specifies the wavelengths over the C and L Bands at an approximate spacing of 0.8nm. The conventional measurement method uses a DWDM/CWDM OPM, and the cost of these meters prevents most technicians from being equipped to test individual channel signal levels in NGPON2 and XGPON networks.

The OWS200 is a cost-effective solution that allows all technicians who currently have a standard OPM to measure signal levels in DWDM/CWDM networks. The OWS200 "splits" the specified wavelengths into individual ports that are then connected to a conventional OPM.
