I am in the middle of purphasing a large amount of composite
fiber optic cable. I have pulled some technical specifications
from this conference and added them to my RFQ which I've sent
to the cable vendors. Everything so far has come back from these
vendors following DEC FDDI specification. But, now because it is
such a large contract the vendors are claiming their fiber is
better than the other guys. I know that these vendors have worked
with DEC engineers to meet our specifications, or at least they
have claimed too.
How can I qualify these vendors and their cable. I also have a question
about the glass manufacturers, I've been told that there are only
three, Corning, AT&T and Spectrum. Have these three manufacturers
qualified their cables to DEC's FDDI specification?
Any help would be appreciated.
Thanks
Dave

If the cable is specified for FDDI and rated at 1300nm, then it should
be ok. When installed the fiber HAS to be tested for loss and any fiber
problems will probably come to light (No pun Intended) at that time.
We recommend 850/1300nm dual window multi-mode cable, which can be used
at 850 for ethernet or 1300 for FDDI. Cable vendors that I have talked
to are AT&T and Siecor, but I don't know if siecor makes it or just
buys it from someone else. I've heard some good things about Corning,
and they are working on or are making a cable with a very even loss per
foot.
