Tài liệu CENTURY BANK AVERTS COSTLY REWORK DUE TO CABLING CHOICE pdf

CHALLENGE
When it comes to any IT project, sometimes it takes a little luck to
bring a project in on-time and on-budget.
For the cabling infrastructure of the Century Bank project, it was
lucky that ADC cable was specified—lucky because the choice of
cable averted a two week project delay and thousands of dollars of
unplanned expense.
PROJECT HITS A SNAG
Century Bank and Trust is a state-chartered full-service commercial
bank operating 22 full-service branches in the greater Boston area.
The construction project was a new 50,000 square foot headquarters
and new main office branch located in Medford, Massachusetts.
The project plan called for
3
⁄4 inch conduit pipe to be installed
in the ground floor concrete slab for routing of horizontal cable to
workstations. Long after the floor was poured, the electrical
contractor waived a red flag—there was no way to pull the specified
eight copper cables through the installed conduit.
At that time, the project team was resolved to sawing the concrete
floor to install larger conduit—an expensive and time-consuming
operation that would put the project behind schedule. Luckily for
Century Bank, the solution was already in hand.

CASE STUDY
AIRES
™
TECHNOLOGY DETERMINES WINNING BID
In selecting the cabling solution for the project—long before ground was broken—analysis of several
cabling vendors settled upon the ADC AirEs
™
cabling solution. It was determined that AirEs cable
offered superior performance at a fair price. The name AirEs—Air Enhanced System—defines the
competitive advantage of using air as conductor insulation. AirEs technology is used for all ADC
Category 5e, Category 6, and CopperTen
™
10 Gbps cable.
One of the fundamentals of producing high-quality cable is good Dielectric Constant of cable insulation
material. Lower Dielectric Constant of insulation means better resistance to breakdown when an
electrical field is applied—stronger signal strength.
In terms of Dielectric Constant, the best cable insulation available is air. By creating integrated air
pockets within traditional FEP insulation, AirEs cable insulation achieves a Dielectric Constant of about
1.8—a 31% improvement over an FEP-only insulation. With the advanced insulation, AirEs cable
showed not only strong signal strength, but also reduced propagation delay and lower delay skew at
the full 100 meters. Combined with ADC’s reputation for consistent, high-quality products, the AirEs
technology earned the winning bid.
AIRES TECHNOLOGY PREVENTS PROJECT NIGHTMARE
While it may have been consistent quality and superior electrical performance that initially won the bid,
a resultant benefit of AirEs technology is significant reduction of insulation material. When compared to

other same Category cables, AirEs achieves as much as 32% reduction in cross sectional area—which
means fill rates as high as 32% higher than with other cable solutions.
For Century Bank, the choice of AirEs meant that the specified eight cables per conduit really were
going to work.
“We were ready to saw the floor,” said Jason Melius, vice president of information systems for
Century Bank. “Luckily, our manufacturer’s rep got wind of the situation and stepped in. He met with
the electrical contractor and showed him the small diameter of the (AirEs) cable that was already
specified for the job. All of my problems went away. The electrical contractor was happy. And I didn’t
have to spend thousands of dollars coring the floor,” said Melius.
CONCLUSION
What started as a buy-in on a high-performance cabling solution ended up saving thousands of dollars
of construction costs due to the thinner, advanced design of ADC AireEs cable.
“The cabling we chose was definitely of better quality than the typical cable available on the market,”
said Melius. We also found the quality of jacks and connectors, the entire line-up of products, was just
better quality. Most important, we kept the project on schedule,” he said.
