Note. Fibre Optic Handling
Fibre optic equipment requires careful handling as the fibre components are very
sensitive to dust and dirt. If the fibre is disconnected from the modem, the protective
plug on the transmitter/receiver must be replaced. The protective plug must be kept on
during transportation. The fibre optic cable must also be protected in the same way.
If this recommendation is not followed, it can jeopardise the warranty.
Cleaning of the optical connectors
In the event of contamination, the optical connectors should be cleaned by using forced
nitrogen and some kind of cleaning stick.
Recommended cleaning fluids:
• Methyl-, ethyl-, isopropyl- or isobutyl-alcohol
• Hexane
• Naphtha
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.
