Improving Grade of Service (GOS) While
Reducing RF Channels
Wireless service providers are adopting new deployment strategies
to reduce network costs and improve quality of service. In one
urban market, a major national wireless service provider has
improved network traffic loading and significantly boosted network
RF performance by centralizing radio equipment and deploying
digital RF transport technology. The digital RF transport systems
operate in simulcast mode and reproduce the signal at radiating
points throughout the network. The new network architecture has
produced trunking and channel re-use performance gains that
enable the service provider to deliver greater GOS while reducing
the number of RF channels....

It may sound bold to say we have the best video jacks in the world, but we can say it with confidence. Just
take a look inside one of our Super Video Jacks and you’ll see why. Our jacks are loaded with features that
make them work more reliably and last far longer than other jacks.
To achieve SMPTE 292M high-frequency performance and minimize signal radiation in or out, ADC
standard size jacks feature a unique, patented, two-piece sliding center conductor. Also, the center
conductor employs a special closed-entry design to resist insertion of a damaged connector or a test probe,
preventing damage. The precision, gold-plated...

Facing the prospect of delivering bundled services that are nearly as complex as
the subscribers who demand them, today’s service providers require an evolved
network that can bring more bandwidth to more places. The combination of
network technologies that can increase bandwidth and connectivity solutions
that can ensure optimum reliability and improve service quality is essential in
meeting the growing demands by business and residential customers.

Active equipment manufacturers are increasingly building DWDM transceivers that use the
multifiber MPO connector. While the MPO provides a compact interface on the transceiver card,
most service providers require single-circuit access. This creates the need for a conversion from
the multifiber MPO to a single-fiber connector. ADC’s Fiber Management Tray (FMT) is a compact
two rack-unit termination panel that features industry-leading cable management and ADC’s
sliding adapter packs, thereby enabling safe single-circuit access. The FMT can also be configured
with high-quality MPO to LC breakout cables that provide the connectivity between the DWDM
transceiver and the FMT panel....

As network equipment such as routers and switches, continues to evolve,
changes in proper cable-management techniques and recommendations must
also keep up with the times. Routers and switches are being marketed with
higher densities and more capabilities. These higher-density platforms have more
cables feeding them and require more power. More powerful equipment gives
out more heat, so careful airflow and thermal management is more important
than ever. Density within a single cabinet is increasing. Upgrades every few years
(or less) are to be expected, therefore cables should be routed in a way that
maximizes accessibility and intuitive maintenance. When as much as 70 percent
of network down time can...

The continued thirst for energy
is a recurring story in news
headlines every day. Global warming
forecasts rising temperatures, melting ice, and population
dislocations due to accumulation of greenhouse gases in
our atmosphere from use of carbon-based energy. There
are strong arguments for and against the dire predictions of
global warming, yet one fact is undeniable—over the past 10
to 20 years, the inhabitants of Earth are collectively consuming
more energy at a faster rate than ever before.

Increasing capacity and network applications create new challenges for both the
planners who design and the operations personnel who maintain the network.
A managed density approach that takes a long-term view of data center design
is key to ensuring maximum density and growth without disrupting operations
that can cause a huge drain on productivity, profits, and service availability.
Successful network managers should always take into account the importance
of planning and maintaining data centers to maximize density and minimize
maintenance hassles....

What’s inside counts. That statement sums up customer expectations about
wireless service inside offices, homes and public places such as malls, hospitals
and subway stations. Wireless service providers have a vested interest in meeting
those expectations: When consumers and business users are convinced that
indoor coverage is reliable and nearly ubiquitous, they’re far more likely
to believe that their mobile phone can be their only phone. That belief helps
wireless carriers’ bottom lines by increasing average revenue per user (ARPU)....

Deploying fiber to MDUs, such as apartment complexes, condominiums,
townhouses, and other multi-family locations, represents a lucrative market for
broadband service providers. At the same time, these applications present unique
challenges in both greenfield and overbuild scenarios. This paper addresses the
key elements of MDU construction practices, including the physical plant from
backbone to premise and the architectural decisions required for a successful
MDU application. It will also cover additional network considerations for
equipment and connectivity techniques....

When IP-enabled picocells first came onto the scene, they appeared to
offer a new alternative to operators facing difficult coverage (and capacity)
challenges. But they also made operators feel a bit uncomfortable. Using
IP for backhaul made a lot of sense… but it was unfamiliar for network
planners used to their trusted tools.

The choice between angle-polished connectors (APCs) and ultra-polished connectors (UPCs) can make a significant impact
on how a particular network will perform. There are several considerations to make, including the network design or
purpose and the types of services that will be transported over the fiber. This paper will compare and contrast these two
categories of connectors, highlighting their differences in terms of physical appearance, insertion loss and return loss
characteristics, as well as their overall performance in particular applications....

The introduction of the Internet in the mid 1990s revolutionized the
telecommunications industry. Voice, data, video, security, and building

now become digitally based, allowing all forms of communication traffic to
converge over a common infrastructure using Internet Protocol (IP) technology.

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....

Deploying optical fiber throughout mid-and
high-rise multiple dwelling unit (MDU) buildings
presents service providers with a mixture of
challenges due to the inescapable fact that each
MDU building is unique. Cable pathways and
distances between logical distribution points
vary from building to building, a situation that
complicates materials ordering and lengthens
installation efforts. Even though the building
owner views fiber to each living unit as a
tremendous benefit to attract and retain
tenants or unit owners, the reality is that
the owner really wants the installation team
in and out of the building as quickly as possible....
