Fibre Optic Cable Question:

Hello people, sorry for asking such a dumb question but networking is not my thing.

I understand how Fibre optic works by sending light beams down the cable. What i dont understand is the following:

How many fibre strands are there generally in a normal fibre cable?

And if a network of 20 computers where connected together with a switch and the server was located in a completely different building connected by a fibre optic cable, how many fibre strands would be used to connect the server to the switch. What i'm getting at is say there was 5 seperate networks in one building and all the servers where located in a different building connected by the proposed fibre optic cable. Could you connect each network to its own server by using different fibre strands of the fibre optic cable?

Depends on the implementation. You can use one cable if you so wished although corprate peeps might scale differently for security/redundnacy issues
 
It is just for theory purposes all I need to know is if it is possible to connect 2 or more networks to their respective servers via different strands of a single optic cable. If is possible is there a specific equipment needed?

You have said in your reply depends on the implementation, can you expand on this please?

Or if you had to connect 2 or more networks to their respective servers in a different building via a fibre optic cable how would you go about it?

I was quite aware of that from the wording of the oriignal question

all I need to know is if it is possible to connect 2 or more networks to their respective servers via different strands of a single optic cable.
Already answered :)

Other than 'normal' fibre optic equipment, not really

You have said in your reply depends on the implementation, can you expand on this please?
You mean do the assignment? ;)
 
I dont want you to do the assignment i just don't fully understand if it is possible to connect more than one network to its server through a single fibre cable. From your answer i take it that it is possible but its not the best way of doing it. But if i had a network connected by a switch then the switch connect to a media converter onto the a strand within thefibre cable. At the other end another media converter connected to that particular fibre strand and then connected to the server via a switch it would work?
 
It is possible since a photon of light is extremely small even in comparison to the diameter of the strand. You can thus have multiple photon streams (rotated about the lengthwise axis so they dont polarize/interfere with each other).

Think of it as a massively parallel-ized serial connection (no pun intended)

If the network is connected to a switch then you shouldnt have a problem ... noit if you are connected to a router then it might be a different issue if one of the devices on the other end of the strand is also coinnected to a router (i.e., router dominance issues) but other than that it shouldnt be too horribly difficult to configure i wouldnt imagine.
