Re: Re: Fibre Optice Advice

Nigel,

I've specified/bought pre-terminated fibre before and it's a viable option
provided your installation contractor is reliable. In most cases it was
bee=
n
installed without incident, however on one particular site it really got
trashed and we had to bring in the supplier  to re-terminate one end of the
cable. Make sure you specify a pulling eye & protection for the
"free" end
of the cable to protect it as it's drawn around the site.

I used to specify Dynamode media converters, but like another poster I've
changed over to Hirschmann kit a while ago and have been very pleased with
it.

My rough-n-ready estimate for 4-core fibre is =A3120 for the terminations
(8-off) plus =A31/m for the cable, so a 50m run would be in the region of
=A3170, plus VAT. I can let you have the supplier and the spec of what I
bu=
y
if you send me a mail off-list :-)

HTH,

Tim.
