Some monumental breakthroughs have taken place in optical fiber cables
and their ability to bend around sharp corners without increasing attenuation
– but today’s technicians and installers may be receiving mixed messages. This
paper will highlight the potential issues surrounding these new fibers as they
apply to the people who handle and install the cables in fiber-to-the-premise
(FTTP) applications.

Reduced bend radius fiber products are making their presence felt across the
fiber-optic telecommunication industry. The main benefit of these new fibers
is their ability to bend more tightly than their traditional counterparts with
no discernable increase in attenuation. This characteristic enables easier fiber
installation, particularly inside structures, promising many new applications for
fiber-to-the-home (FTTH) architectures. These fibers will likely have the most
dramatic affect within the multiple dwelling unit (MDU) environments....

Reducing up-front expenses in any FTTP architecture plays into every decision
a carrier makes about solutions deployed in any particular situation. Reaching
customers quickly and easily with robust, flexible, and reliable connectivity for
delivering voice, data, and video services requires careful planning and good
decision making. The introduction of hardened connectors and drop cables
using multiport service terminals (MSTs) enables carriers to accelerate FTTP
deployment, provide rapid service turn-up and enable operational cost savings
throughout the life of the network....

Integrated Cable Organization Network (ICON®)
brings clean, simple order to any professional
audio/video production.
The ICON Main Distribution Frame system pulls all
of your audio, video, and data cabling together
into a neatly organized central termination and
distribution point where interconnections are
easily managed.
Compared to point-to-point cabling, this system
saves time and money, reduces the number of
cables and cable disorganization at the equipment,
and allows you to change connections quickly,
and provides critical system redundancy.
ICON systems use fast-installing and reliable QCP II
or QCP IV punchdown connectors. Input
connections punchdown on one side of the unit,
output connections on the other side, and jumpers
to interconnect them punch down on the back....

ADC’s new Optical Normal Through Panel is the latest addition to its Pro Patch line of broadcast patching
products. This new fiber panel is designed to provide patch by exception, normal through functionality,
similar to copper-based patch panels. Traditional fiber patch panels require a fiber jumper to be in place at
all times. With this newly designed panel, however, all fiber “Source” and “Destination” connections are
on the rear of the panel, with a normal through connection between the “Source” and “Destination”
ports. For greater convenience and reliability, patch and monitoring capabilities are accessed on the front
of the panel....

Today’s cable systems serve up more than just television. Because community
antenna television (CATV) systems now incorporate high-speed data and
telephony services, signal flow is critical for multiple systems operators (MSOs)
and their customers. Signal levels and network configurations must evolve
to meet the new service demands of transitioning headends. The impending
challenge for MSOs is to effectively manage their networks amid change and
maintain maximum uptime for subscribers.
