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
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
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
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
• 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.
