7.4 Fiber-Optic Connectors
Note
Fiber-optic connectors are impaired by dirt and mechanical damage to the end
faces.
Protect open connections with the supplied dust caps.
7.4.1 Connectors for Plastic Fiber-Optic Cables
Fitting connectors to plastic fiber-optic cables is relatively simple. The following
connectors are available:
S
Simplex connector for connecting OBTs and integrated optical interfaces
S
Adapter for simplex connector for integrated optical interfaces
S
BFOC connector for OLM/P
7.4.2 Simplex Connector and Adapter for Devices with Integrated
Optical Interfaces
Definition
Simplex connectors are used to attach the fiber-optic cable to the integrated
fiber-optic interface of the PROFIBUS device. With certain Siemens modules (for
example IM 153-2 FO, IM 467 FO) two simplex connectors (one for the transmitter
and one for the receiver) are plugged on to the module using a special adapter.
Requirements
The PROFIBUS device must be equipped with a fiber-optic interface, such as the
ET 200S (IM151 FO) or the IM 467 FO for the S7-400.
