CONNECTION
Stripping of primary jacket, buffer and coating.
If mechanical stripping is used , we highly recommend :
- To strip directly from primary jacket to silica
- To carefully clean silica with a solvent such as MEK (Methylethylketone).
Residues of silicone can be removed with a wet tissue by wiping off of different angles in order to clean all the circumference of the silica.
If you dip bare fiber into solvent, take care to avoid contact between solvent and other part of the cable such as strength members, silicone and jacket.
