Fitting Connectors On-Site
If it is necessary to fit connectors on-site,
– SIEMENS provides this service (see Appendix I-2)
– BFOC connectors and special tools can be ordered (see I-2).
Note
Connectors for glass fiber-optic cables should only be fitted by trained staff. When
fitted correctly, they allow extremely low coupling attenuation and the value can be
repeated after inserting the connector several times.
Preassembled Cables
To be able to use glass fiber-optic cables with untrained personnel, glass fiber-optic
cables are also available with four BFOC connectors already fitted.
For ordering data, please refer to the current SIMATIC NET Catalog IK 10.
Note
Fiber-optic connectors are impaired by dirt and mechanical damage to the end
faces. Protect open connections with the supplied dust caps.
