1.6. Connector care and cleaning
Connectors for single mode optical fibre are designed for sub micron tolerances. Such a
connector has an optical section of only 9 µm diameter. The optical connector is a high
precision device. It must be handled with care, to avoid scratches and other mechanical/optical
damages that will impair or reduce the system’s performance
The following rules must be carefully followed:
ü Do not leave optical connectors open, as they will attract dirt.
ü Do not touch the connector tip. Clean it with a proper tissue before inserting it into the sleeve.
ü Use pure ethyl alcohol for improved cleaning.
ü Sleeves may be cleaned by injecting pure gas under pressure.
ü Do not attempt to insert connectors mechanically incompatible. This will result in severe damage.
