Distance limit for Option 11C expansion cab 1

[JayTee0518]

Our department is considering options to extend our PBX service to another building on campus located 2600 feet away. We have an Option 11C which currently uses 2 cabinets and are looking at the possibility of adding a third cabinet in the other building. I've looked online at Nortel's site and in our documentation but I can't find anything on distance limits. Will a third cabinet work over a distance of 2600 feet? And if so, is it using single-mode or multi-mode fiber? The current cabs are linked with fiber cable that is orange colored. On the data side of things orange meant single mode and yellow meant multimode but I haven't dealt much with fiber on the voice side.

This should help.

NTDK25 (3km, multimode)with NTDK24 daughterboard
or
NTDK80(3km, singlemode)with NTDK79 daughterboard
