Your VIAVI OTDR has a breakdown ? You wish to send it back for a repair service ? Or just a calibration ? You are more than welcome to open an After Sale ticket through our customer service contact describing the nature of the problem.

We provide a local calibration service in our Paris premises for rapid support of VIAVI Solutions Singlemode OTDR.

If your OTDR has a Multimode or QUAD module (Singlemode + Multimode), the calibration service will be carried out in the European maintenance center located in Madrid.

In case of repair, the service is also carried out in Madrid.

In order to be able to validate the form, it is mandatory to fill in the serial numbers of the equipment.
