Loss limitation

The need for low loss assemblies
in data centres as network
speeds and data increase
As data centres are evolving from 10GbE through to 40 &
100GbE, the need for low-loss multi-fibre connectivity is
vital. As network speeds increase, the optical insertion loss
budgets will become more stringent than ever. Headroom
between the loss budgets and system performance is
reducing and so then does margin for error. No longer is it
okay just to use any compatible looking assembly and hope
for the best; all fibre connector losses must be factored in
and specified as part of the system design and vendors
taken to task over conformance.
With a typical configuration, identified in Fig. 1, the
end-to-end link consists of a patch cord, a cassette (which
includes LC adapter at the front, an LC to MTP fan-out
assembly inside and an MTP adapter at the rear), an MTP
to MTP trunk cable, a remote cassette and a remote patch
cord. This simple system, from switch to server will include a
