economic benefit. The different module options are key
in supporting a forward path. Along with the standard
splice and MPO-to-LC fanout cassettes, there is need for
conversion and patching solutions that enable easy migration
through new technologies (i.e., 40 GbE to 100 GbE)
while enabling use of the existing cabling infrastructure
(Figures 6 and 7).
It is crucial to understand what the roadmap is
of any given fiber management provider. The benefit
of a modular solution is that new modules can be developed
to support new and emerging technologies or architectures.
One example is the nano connector from various
companies targeting primarily the 400 GbE and beyond
architectures. These reduced-size connectors provide
a greater level of density than traditional LCs. Designed
around a ceramic ferrule technology, they do not experience
the same connection repeatability challenges often
observed with MPOs.
It is important that designers and installers understand
that some of the new nano connector solutions
utilizing adapters, certain patch panels, fanouts and
other non-direct LC and MPO connectivity may not
comply with certain industry standards. For example, FIGURE 7: Cassette options.
