Fiber Optic Connection!!!

Tomy Master

I have a project and I need to connect CPU313C-2DP via fiber optic cables (using profibus protocol).
The distances between the CPU's ranges from 300 to 1000 m.
My questions are:
1- What kind of OLM modules do I need?

2- What kind of fiber optic cables do I need (outdoor connection, in a semi arid region).

Hello Mohamed;

Google can truly be a good friend sometimes, you will find manu such equipment from many providers:

I suggest you contact a network infrastructure provider near you; it will make your life easier to have local support for the selection and support of equipment that is adapted to the requirements of your project.

Hope this helps,

Hello,
Well, for your case I suggest you can considerusing the OLM Gxx, type (glass).
Please look at the manual in this link which i think will give you very good information.

SIMATIC NET PROFIBUS Optical Link Module OLM / P11 V4.0 OLM / P12 V4.0 OLM / G11 V4.0 OLM / G12 V4.0 OLM / G12-EEC V4.0 OLM / G11-1300 V4.0 OLM / G12-1300 V4.0 Operation manual

2- What kind of fiber optic cables do I need (outdoor connection, in a semi arid region).

There are two kinds of fiber optic cables. The Glass type and the plastic type. And they are further divided into multimode and single mode.Single mode fiber can send signals much further than multimode.For instance,
a] multimode plastic type can supporttill around 80m,
b] multimode glass type can support till around 400m,
c] single mode glass type can support between 3 to 15km without repeaters.

For your case of 300 to 1000m, the safest choice would be single mode glass type.
As for the region you can look into these wedsite

3- What kind of other accessories do I need?

For accessories, you can consider a patch box or patch panel for neat installation.

 Hello

I have same question. i want have network between cpu 1200 with control room with 500 m distance.in order to convert profinet to optical fiber whats your suggestion? and what type of optic fiber?

best regards 

Hello sajjad;

To my knowledge you can use either dedicated media converters, or switches that combine RJ45 and F.O. ports.

I can provide one link to Phoenix Contacts Profinet hardware that will discuss both kinds of equipment. Note however that there are many providers on the market for such equipment, Moxa, Belden amongst others.
