Description
You can connect single-mode or mono-mode glass fiber optic cables (9/125µm or 10/125µm) to the following PROFIBUS Optical Link Modules (OLM):

• PROFIBUS OLM/G11-1300
• PROFIBUS OLM/G12-1300

The properties of the single-mode or mono-mode glass fiber optic cable must meet the specifications of the optical interfaces of the OLM.
The optical interfaces of the OLM are BFOC sockets. The following table shows the specifications of the optical interfaces of OLM/G11-1300 and OLM/G12-1300.
 

	OLM/ G11-1300	OLM/G12-1300
Number of optical interfaces	2x BFOC sockets	4x BFOC sockets
Wavelength	1310 nm	1310 nm
Linkable optical transmission power referred to 1mW	-19 dB	-19 dB
Optical sensitivity referred to 1mW	-29 dB	-29 dB
Attenuation of the fiber-optic transmission path	8 dB	8 dB
Length of the single-mode or mono-mode glass fiber-optic cable	0 to 15 km	0 to 15 km

Note
More information on the PROFIBUS OLMs is available in the manual

1. PROFIBUS OLM V4.0 in Entry ID 24164176.

QUESTION:
How has the PROFIBUS PA bus to be terminated?

ANSWER:
With a capacitor (C= 1µF) and a resistor (R = 100 Ohm) in series between data lines A and B (pins 3 and 8).

Keywords:
Service

QUESTION:
Can an OLM work with different plastic fiber- as well as quartz glass- fiber cable types?

ANSWER:  
No. An OLM does only support one cable type, not several ones at the same time.

Note:
Further information regarding OLM is available in the manual "SIMATIC NET PROFIBUS Optical Link Module" under entry ID 8331164.
