Hi,
I'm a real newbie when it comes to working with fiber optics, but I want
to do some testing of some Gigabit ethernet equipment, and was looking
for a patch cable. I was in a local Microcenter today, and noticed that
they carried some SC-to-SC cables such as the following:
http://www.microcenter.com/single_product_results.phtml?product_id=0163916
In the above page, it says "You can get nearly unlimited high-speed
bandwidth at speeds up to 100Mbps".
This cable is 62.5 multimode, and the patch cable is 2 meters.
Shouldn't that be able to carry over 2Gbits/sec?
Thanks in advance,
Jim

No, in fact it should be able to carry 10Gbits/sec. Should be able to
run 10 gig ethernet over multimode no problem.
The marketing people at most resellers are idiots.

Hi,
Thanks. It seems to be working fine, though we're only running GigE on
it...

Well...
About the statement below "10 gig ethernet over multimode no problem", this
is not necessarily true. With 2m fiber, it is probably ok. But legacy 62.5um
fiber carry 10Gbps signal only for a couple of 10's of meters.
For multimode fiber there is a bandwidth-length specification such as
160MHz-km. What this tells us is with higher bit rate, less maximum
distance.
