In designing an FDDI net we used to use the following design specs:
1dB max loss per mated ST connector pair and .5dB max loss per splice.
I'm beginning to wonder if this is ultra-conservative and am toying
with the idea of changing that to .5dB max per mated connector pair
and .2dB max loss per splice (mechanical). I figure a 2dB margin in
the budget will take care of any slop. We do a tight QA on all
installations and from what I've seen in terms of connector loss the
.5dB max is reasonable.
What are other folks doing? Comments?
