Default Anyone know the capacitance per meter of T&E cable?

I did once calculate an approximate figure for T&E capacitance -it was
absolutely tiny - picofarads for normal cable lengths, if I remember
correctly.

However I thought data cable length measurement used TDR -time domain
reflectometry - only suited to cables that can be considered to behave
like transmission lines?

I'd guess at 50pF per meter meself..that sort of order..more than ten,
less than a hundred..

If you are really bothered I have an LCR bridge in the workshop..
