RE: High Density Multimode Runs BCP?

a) Find/adapt a 24/48 thread inside-plant cable (either 
multimode, or condition single mode) and connectorize the 
ends. Adv: Clean, Single, high density cable runs, Dis: Not 
sure if such a beast exists in multimode, and the whole cable 
has to be replaced/made redundant if one fiber dies and you 
need a critical restore, may need a break out shelf.


We use multicore fibre cables in our datacentre and nodes.
In Europe we can obtain these to order on specific
size. If we need to bring these back to a central area we 
use an ODF and and then patch accordingly with fibre boxes
in cabinets. The multicores are in a rugged PVC type plastic
sheath [same type of plastic/pvc that is used for gas piping
in the streets here in Europe]. You have to do some serious 
hacking to damage this type of cable, and if you've ever
been to Telehouse in London you'll know how the type
of situation that I mean.

This is the company we use in the UK to do a lot
of this work

I can't recommend them highly enough.

You may also want to look at passive optical stuff that you
can use to cheaply use to do cdwm.

Neil.
