The maximum length for a single thinlan segment is 185 meters, so you
should be fine.  Hooking thinlan to thicklan directly together works 
on the bench or in an emergency, but I don't think it's a very good
idea for permanent installations.  The IEEE specification will tell
you more than you ever wanted to know and is where I go when I have a 
question.
