How "ruggedized" do you need...We use for some ITS/Highway Projects that 
work pretty well....

Fiber Converters, was RE: DS3 Coax..

Andy,

Thank you for bringing up fiber converters.  I have a comment I was
trying to bring to the list that escaped this old man's memory.

To the best of my recollection, I have not implemented a fiber converter
that lasted more than say, 12 months.  I've tried different brands with
no luck.

So, my question is, does a 'ruggedized' fiber/coax/X-baseT converter
exist? 

Regards,

735 DS-3 cable has a specification max length of 225'.  734 DS-3 cable
has a specification max length of 450'.  When you use this long cable
length, the mux that is providing the DS-3 needs to have the pads
removed (or provisioned) for a long cable run.

Transition Networks (and others) make DS-3 fiber converters.  They are
not cheap.  This would be my preferred method as fiber (especially OSP)
is much better suited for outdoor exposure and temperature changes.
