Hi all,
Any body know what is the maximum bandwidth that a fibre can carry ?
As I know, 3550 layer 3 switch support 1G, a 6509 switch can support 10G. Does the fibre bandwidth is depends on the hardware termination point ?

Hi,
A single / dual fibre can carry bandwidth in terms to Tb, as you have mentioned it depends on the media converter used at both ends of link, model of router and interface on which it is terminated.

Hello,
there are limitations due to physics and also fiber type. A multimode fiber will not allow you to achieve terabits because of the inherent dispersion (among other things).
With a single mode fibre the underlying physics for transportation is different allowing for much higher speeds.
The carrier frequency of light is in the hundred terahertz range so terabits would be the maximum range expected. Dampening i.e. absorption because of different physical effects like phonons, frequency dependant dispersion will give you an upper limit. Another limiting factor is the signal to noise ratio required by receivers.
Bottom line: as the posting above already stated, in most cases today the terminating equipment is the limting factor.

ic...is it means that the most bandwidth consumed equipment such as "DWDM" that can transfer multiple frequency via 2 core fibre can obtain the most bandwidth in terms of tera bits
