TECH BRIEF
3 Common Subsets of FTTx:

FTTN (Fiber to the Node)
In this architecture, fiber is used to transport data to an
access node that serves a large number of nearby customers. The “last mile” connection (which may be much longer
than a mile) to individual subscribers is carried over copper
lines, which are already deployed in mostareas.
FTTC (Fiber to the Cabinet)
The next major progression from FTTN is FTTC, in which
fiber extends much closer to the customer’s property. As an
example, fiber might extend from a node to a cabinet that
serves a few dozen homes in a neighborhood. FTTC reduces
the distance data must travel over copper lines, increasing
bandwidth.
FTTH (Fiber to the Home)
In the FTTH model, fiber continuesall the way to a box on
the customer’s property, typically attached to the house.
This eliminates all copper use between the provider and the
customer site, which skyrockets the bandwidth that can be
provided.

In an environment where most existing home sites already have
copper but not fiber connections, the costs of various FTTx
options vary wildly. To retrofit your network for FTTN(Fiber to
the Node), you only need to replace major lines that feed your
limited number of nodes. For full FTTH, you also have to replace
an exponentially larger number of node-to-cabinet lines, plus a
cabinet-to-premises fiber for every customer.
This wide swing in cost must be balanced against the revenue
you can expect to create. For IPTV and other bandwidth-intensive
applications, FTTH maybe the best option. For reasonable broadband internet performance, however, the majority of your service
area will probably be satisfied by the much cheaper FTTN option.
Of course, in new housing developments where no lines have
been deployed yet, FTTH makes a lot of sense. In fact, that’s the
biggest growth area for FTTH deployments in the United States.

AlthoughFTTH (or, for businesses, FTTP: Fiber to the Premises)
is the most commonly referenced “Fiber to the...” architecture,
there are actually many. “FTTx” refers to this group of related but
functionally distinct technologies.

After reading about subsets of FTTx, the most common reaction
is to choose FTTH as the best option. While it certainly provides
the best performance, there is someimportant exponential math
to consider.

Fiber optic communications infrastructure is spreading rapidly
around the world. To keep up with this trend, you need to understand the basic concepts of Fiber to the Home (FTTH) and similar
network architectures. This guide is your fast tutorial to FTTH.

This Technique Boosts Your FTTx Bottom Line

Write this down: Network alarm monitoring is critical for FTTH deployments. After you’ve invested time, effort, and a lot of your
budget dollars to provide fiber servicesto your customers, you simply must protect your investment. If you don’t, your revenue will
likely shrink from preventable outages, and your costs will climb because you don’t have the right tools to operate efficiently.
Fortunately, it’s easy to monitor your nodes and cabinets - if you choose the right monitoring gear, that is. You might be familiar with basic LAN-based alarm remotes. Theycollect alarms reported by your equipment and environmental sensors, then report
those alarms back to you. But LAN-based equipment isn’t optimal in FTTx enclosures.
You need to choose an alarm remote that reports alarms directly over fiber. You’ll never have to worry about breaking LAN out
just to feed your monitoring equipment. That’s the secret to gaining the benefits of alarm monitoring at...
