Optical networks with glass fiber-optic cables

■Overview

We recommend use of glass fiber optic cables with 2 multi-mode fibers for optical PROFIBUS networks in indoor and outdoor ar- eas.

The standard FIBER OPTIC CABLE is available in fixed lengths for distances up to 2000 m, preassembled with 4 BFOC connec- tors. A BFOC connector set with 20 connectors is available as an accessory.

Further fiber optic cables can be found in Catalog IK PI, Chapter "PROFIBUS", Section "Optical networks with OLM".

Optical Link Module

Optical Link Modules (OLM) permit the construction of optical and hybrid (electrical/optical) networks in line, ring or star topol- ogy. The maximum distance between two OLMs can be up to 15 km for OLMs of type G12-1300 (see Catalog IK PI) and glass fiber optic cables with single-mode fibers (on request). The PROFIBUS OLM/G12 used as standard is equipped with one RS 485 interface and two glass fiber optic cable interfaces

(4 BFOC sockets). The fiber optic line length between two OLMs of this type can be up to 3000 m when using the standard FIBER OPTIC CABLE.

The OLMs have a compact metal housing suitable for DIN rail assembly. They automatically recognize all PROFIBUS data transfer rates. Faults can be rapidly located as follows:

•Display of module status via floating signaling contact

•Checking of FO link quality (loss per section) via test output for optical receivers for logging and plausibility checks.
