The front surface of the connectors must not be contaminated.
If the connectors are disconnected: connect the Fiber-Optic Repair Set - Connector Protective Caps:VAS 6223/9 from the Fiber-Optic Repair Set:VAS 6223A .
When routing fiber-optic cables, make sure not to go below the minimum bending radius of 25 mm. Do not crush or kink fiber optic cables.
