How do I carry out a PON-FMT acceptance test in accordance with ZTV43?
When carrying out acceptance testing on a GPON or XGS-PON connection, it is not enough simply to measure an optical level. What is crucial is whether the measured value corresponds to the actual network topology and whether the technician is in fact at the intended PON branch. The PON-FMT acceptance test…

How do I carry out a full check of an FTTH connection – from the fibre optic cable right through to the internet?
An FTTH connection may be technically flawless yet still fail to work properly for the customer. For example, a good PON signal level does not necessarily mean that the ONT will register correctly, that an IP connection will be established, or that the subscribed data rate will actually be achieved. A comprehensive test…

How do I find out where a fault is on an active PON?
An optically low signal level at a GPON or XGS-PON connection initially only indicates that there is a problem – not where it is located. To carry out targeted troubleshooting, the technician must therefore determine at which point along the fibre-optic link the abnormal attenuation…

How can I test a GPON or XGS-PON connection if the ONT fails to register?
If an ONT fails to register with the OLT, this does not automatically mean that the ONT is faulty. The cause may lie at various levels: with the fibre optic cable and the optical signal level, with the assignment to the correct PON, with ONT authentication, or…

How can I measure GPON and XGS-PON simultaneously on a single fibre?
GPON and XGS-PON can be transmitted in parallel over the same optical fibre, as both technologies use different wavelengths. For the technician, this means that several optical signals may be present simultaneously at a single connection. In order to assess these correctly, the individual…

When do I need a power meter and when do I need an OTDR for FTTH?
During the installation, commissioning or troubleshooting of an FTTH connection, power metres and OTDR s are used for different tasks. An optical power metre (OPM) measures how much optical power reaches a specific measurement point. An OTDR (Optical Time Domain Reflectometer), on the other hand, analyses the…
