Please log in for more thread options Hello all. I need to replace an old building-to-building 50-pair burried cable (for voice) and was wondering if I can use an existing Fiber run. If so. What do I need on each end of the run? copper -> fiber / fiber -> copper device?
I'll appreciate any input as I'm new at this. Regards, - Frank | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Very carefully, split the fibre into 50 slivers. ;-) Actually, the answer depends on what you want to carry. Voice? Data? Network? Etc.? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

James. I had a heck of a hard time splitting a single fiber strand into 50 slivers but by the end of the 48th hour I was successful. Now it works great. NOT. I just want to carry voice. What I need to know is if there is an interface out there that will convert fiber into cat3 copper. I also have more than for strands available on my fiber. Thanks. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

So you're looking for a 50 channel voice (POTS I'm guessing) to fiber converter/multiplexer/demultiplexer. Not a trivial thing. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
