Router to Router Distance

[basharmuhanna]

Hi there, 

I am working on a campus network diagram on PKT, and I have two branches with a distance of 10KM between them, I have used a Fiber cable to do so.

My Question is, is it possible to set a 10KM distance between the Routers?

It is possible, however, please provide the following information: 

1.  What is the exact distance of the fibre optic link? 

2.  What speed?  100 Mbps, 1-, 10-, 25- or 100 Gbps?

Thanks for replying,

In the task, it says the branch campus is located about 10 km from the Main Campus Network, for the speed nothing mention here, advise me on it (Which speed is most suitable)?

If the routers have "right" optical transceivers and you have the "right" fiber, yes you can interconnect the two routers.

For example for 10K, SM fiber and gig LX/LH or for 10g, LR or LX4 optics should work.
