[ILUG] [OT] ethernet repeaters

[Mark Kilmartin]

AFAIK the figure is 5.

So this would allow you to have a switch at both ends and then up to 3
more in between.

Of course if you need to go further then maybe you could consider adding
in a Linux based router in Between, of course this may not be an option
in your setup.

But Fiber is definitely the way to go.
It doesn't care if it is ran alongside power cables.
Just beware when turning a corner with it as most fiber has a minimum
corner radius of about 2 inch.

Also be careful of not placing anything on top of fiber.
Since it is a glass strand if anything heavy is placed on top of it(e.g.
a foot) it can shatter the glass and you'll notice a lack of packets.

Also 100baseFL which is the normal 100Mbit fiber connection is limited
to 2Km (you can get technologies that use a different type of fiber(more
expensive) that can overcome this limit) Or of course use a couple of
ethernet repeaters.
