Measurement methode
Check a PON (Passive optical networks)
1. Connect the cleaned end of the optical cable (begin PON) to the
measurement socket of OME 100. Pay attention to the notch!
2. Switch the optical transmitter OME 100 on, pay attention to the switch-off
automatic and deactivate this if necessary (page 11).
3. At the display of OME 100 is now the measurement wavelength shown. For
SAT-IF transmission is regularly used 1310 nm. CATV-systems with
forward- and return path can be measured with 1310 nm and 1550 nm.
4. Connect the OME 200 to the cleaned end of the PON you want to measure.
Pay attention to the notch!
5. Switch the optical measuremrent device on, pay attention to the switch-off
automatic and deactivate this if necessary (page 11)
6. At the display is the selected wavelength and the incoming optical power
shown. The wavelength has to match with the selected value of the source.
SAT-IF normally 1310 nm.
7. The displayed level is the result of the source level (at OME 100 -7 dBm)
minus the attenuation of all connected components (cables, splitter,
adapters, etc.).
Typical attenuation values:
2-way splitter (e.g.: Polytron OSF 200) 3,6 dB
3- way splitter (e.g.: Polytron OSF 300) 5,8 dB
4- way splitter (e.g.: Polytron OSF 400) 7,0 dB
8- way splitter (e.g.: Polytron OSF 800) 10,2 dB
Each connector typ. 0,2 dB
Optical cable typ. 0,2 dB / km
