Deploying a successful fiber-to-the-premise (FTTP) network requires careful planning and
execution. It is clear after many years of trials that FTTP is here to stay. Taking FTTP
networks from the lab/field trial mode to full-scale network deployment presents many
significant challenges for service providers. One of these challenges is deploying the
network for the lowest possible cost, while creating a fiber network infrastructure that
has the flexibility and reliability to last long into the future....
Today’s service providers are under tremendous pressure to ensure their
networks are profitable. When it comes to fiber-to-the premise (FTTP)
architectures, ADC has done its homework. ADC has helped providers
maximize profits while minimizing expenses, and offers several white papers
which explain considerations and techniques that can be applied to particular
sections of the FTTP network to increase performance, flexibility, and profitability
by decreasing capital expenses (CAPEX) and operating expenses (OPEX).
GPON is a culmination of the best in BPON and EPON techniques. Most agree
that eventually, everything will move to IP (voice over IP, video over IP, robust
data applications like gaming, video streaming, MPEG3 downloads), and
quadruple play applications (network appliances, security, video surveillance).
The advantages of GPON are key in driving commitment by the large volume
carriers to the GPON standard. As GPON moves to become the standard
of choice for fiber-to-the-premise (FTTP) networks, cost reductions and
inter-operability will accelerate....
Gazing into the future may be possible for the few clairvoyants living among us,
but building a telecommunication network based on psychic prediction would be
like basing critical business decisions on a coin flip. Still, today’s telecommunication
buzzword for any fiber-to-the-premise (FTTP) network is “future-proofing.”
Without a crystal ball to examine future bandwidth needs and determine winning
technologies, service providers face some major challenges in getting it right the
Convergence is a word many of us in the industry grow weary of hearing.
It oozed from the mouths of marketers during the dot-com explosion and
even during its violent implosion. Now, as our market moves from survival
to recovery mode, the word has begun to take on a life of its own once
again. It seems that convergence is as popular in the telecom world as
other over-used catch phrases such as Next-Generation Networks (NGN),
Quality of Service (QoS), and Scalable Networks.
In today’s and tomorrow’s fiber-to-the-premises (FTTP) architectures, the best solution for
offering multiple services to subscribers will be the one that is the most cost effective,
flexible, and scalable. With its 65-year history of innovative solutions for managing the
physical cable plant, ADC is bringing all its experience to bear in the outside plant (OSP)
and fiber-to-the-premises (FTTP) markets. Driven by the customer’s need for overall
affordability and operational flexibility, ADC is designing and building the first true FTTP
solution – from the ground up....
In the distribution portion of the passive optical network (PON) for fiber-tothe-
premise (FTTP) architectures, the choice of fiber cabling – ribbon vs. loose
tube – can directly impact ease of installation and future performance. As is
usually the case in these networks, specific architectural characteristics and
particular applications may dictate the deployment of one type of cable over
A Connector is a device used to provide a semi-permanent link between two optical fibers. Connectors must be able to maintain good optical contact between the fibers at the connector interfaces. In theory, only the cross sectional face of the two fibers need to touch, hence the term Physical Contact (PC) connector is used.
The basic components of a connector include the body, the ferrule, the barrel (coupling nut/insert), and the boot. The body is the physical shell of the connector, which houses the mechanism used to secure the fiber to the connector.
ADC’s rugged, high performance Indoor/Outdoor Drop Cables are used in FTTP networks to make
drop connections from Fiber Distribution Terminals to the Optical Network Terminal (ONT) at the
living unit typically found in multiple dwelling unit (MDU) applications. Applications include, but
are not limited to situations where cables are transitioning from an outdoor to indoor environment.
The bulk non-connectorized cable is shipped on small spools for easy payoff.
The successful deployment of any flexible, cost-effective fiber-to-the-premise (FTTP)
network requires thoughtful decisions regarding all segments of the network, from the
optical line terminal (OLT) in the central office to the optical network terminal (ONT)
attached to each home and everything in between. While much attention is focused on
the distribution and access elements within the outside plant (OSP) network, it’s also
important to consider the implications of FTTP architectures within the central office (CO)....
Fiber-to-the-premise (FTTP) architectures are presenting both new challenges and
new opportunities regarding the use of connectors in the outside plant (OSP). At
no other time have connectors been as necessary in OSP architectures – and they
are destined to become even more prevalent in the days ahead as the FTTP
networking market continues to gain momentum. Service providers competing for
the FTTP market require the same flexibility in test access and the ability to
provision that they have typically enjoyed in the central office. They need to scale
service in a cost-effective manner....
Fiber-to-the-Premises (FTTP) networks increasingly include Multiple Dwelling
Units (MDUs) such as apartments, condominiums and townhouses as part of the
network build. Some estimates indicate that MDU structures may account for over
one third of the target FTTP subscriber base. These MDU installations require special
consideration for fiber cable interconnection to terminal equipment located at the
premises. Connecting MDUs into the FTTP network requires an understanding
of the wide diversity of structures and conditions found throughout the country.
Advanced fiber management systems incorporate the latest techniques for optimizing access
networks for accessibility and time required to reconfigure, perform maintenance, or troubleshoot
problems. Successful fiber management plays an increasingly important role in eliminating potential
problem areas that can become both costly and time consuming over the life of the network.
Although it’s fair to say the distribution and access elements within the outside plant
(OSP) portion of the fiber-to-the-premise (FTTP) network demand the majority of
attention during deployment, it’s still important not to overlook implications to the
central office (CO). Any FTTP network requires the same flexibility as the transport
network—and it all begins in the CO.
The ADC Outdoor Fiber Distribution Terminal 48F (oFDT-48) is designed to terminate, splice
and interconnect fiber optic cables in an outdoor environment. This terminal may be adapted to
Fiber-to-The-Premise (FTTP) Multiple Dwelling Unit (MDU) applications by mounting the enclosure
to the exterior surface of a dwelling and connecting between the distribution cable and drops
routed to individual living units. The oFDT-48 is typically divided into two side-by-side sections
with distribution cable routed into one side and drop cable routed into the other side.

Fiber Distribution Hubs (FDH) continue to play a vital role in supporting rapid
deployment and connection in FTTP networks. Innovation in FDH design occurs
at a rapid rate and next generation features appear in newer FDH enclosures.
Key innovations include:
Passive Optical Network (PON) infrastructures deployed in fiber-to-the-premises (FTTP)
networks require numerous fiber connections to achieve the distribution of services to
multiple homes. Although splicing has its place in these systems, use of reliable anglepolished
connectors (APCs) provides numerous advantages in terms of overall network
flexibility, testing and troubleshooting.
