Hospitals and Clinics (Stanford, California) are renowned for their progressive
medical research and subsequent successful life-enhancing treatments. Throughout
their century-long history they have pioneered medical advancements to save lives
and protect from diseases. One of the most famous accolades of this teaching hospital
is that they performed the first successful adult human heart transplant in the
country and the first combined heart-lung transplant in the world. To expand their
research studies and to bring together leading scientists, Stanford recently built
a new Center
for Clinical Science Research, known as the CCSR.
planning for the CCSR, they wanted to incorporate the most technological advancements
for this research facility. They required a highly sophisticated telecommunications
infrastructure that could handle their myriad of applications from real-time full-motion
video transmission between instructors and labs, as well as high-speed data research
and transfer. Their planned configuration included a switched 10baseT/100baseT
network with telecommunication closets utilizing gigabit Ethernet connection.
While reviewing the many products and systems available, they were also looking
for a system that could enhance their current standard to be incorporated in other
new and existing facilities on their campus. Their standard, combining fiber and
copper for the backbone was utilized. To provide high-speed data and voice to
each lab and office, they selected Helix/HiTemp Category 5e cabling and Leviton
Telecom connectivity products for a total end-to-end solution.
In The CCSR
Creating and using technology that will break through
barriers and uncover new scientific knowledge are key aspects of the Stanford
Medical School's research mission. On-campus are 47 different lab research groups
scattered through the medical facilities and in the two hospitals - Children's
and Stanford Medical Center.
CCSR, which was designed in 1996 and will be completed by summer of this year,
focuses on consolidating all their biomedical researchers into one location. This
facility is two mirror image four-story buildings connected by a bridge and an
open-air atrium. The buildings total 220,000 square feet of administration, faculty
support offices, a computer learning room, and wet and dry labs including cadaver
is a first class sophisticated research facility," states Bob Moya RCDD,
a Sr. Project Engineer for the Communication and Networking Services department.
"When we designed this facility, we reviewed many networking systems and
products to make sure it could easily handle high bandwidth applications. We knew
we had to install a networking system that could also handle applications in the
future without becoming quickly obsolete.
Backbones to Dry Bones
After reviewing many of the cabling and connectivity products, Stanford selected
a variety of cabling media - fiber, twisted pair copper and even coax.. SuperCAT360,
enhanced Category 5e UTP (unshielded twisted pair) cables from Helix/HiTemp Cables
(Franklin, MA) for the data and voice cable plant for the 6,000 horizontal drops.
The backbone / riser consisted of Category 3 for voice, and fiber for data. Fiber
optic cable, consisting of 24 multimode/12 singlemode, was placed in the riser.
In some instances, multimode fiber was brought to the desk. Coax cable, which
was a .500 hardline, was provided for video and broadband transmission. Walker
Communications (Livermore, CA) was the selected vendor for the entire telecommunications
main telecommunications room is located in the basement of the North Building.
Each of the four floors in both complexes house a telecommunications closet, also
known as an ICC (intermediate cross connect). There are four ICCs in each building,
totaling eight for the entire facility. The voice cable is terminated on 110 blocks
for both the riser and station cables. The fiber optic cable backbone is terminated
into the fiber termination splice boxes and jumpered to an Extreem Networks 10/100
switch with gigabit uplink capability. From there, the cable is then patched to
the Leviton Telcom GigaMax System's 48-port patch panel, which provides
Category 5e channel performance and horizontal connectivity from the closet to
the workstation outlets. The horizontal cable, Category 5e, which is installed
in cable tray, is terminated into the Leviton Telcom GigaMax TSOs (telecommunication
station outlets) at the workstation locations.
is close to one million feet of cable within the facilities. Of that, 900,000
feet of Helix/HiTemp's SuperCAT360, plenum cable was pulled to provide horizontal
voice and data to each workstation outlet. "Although Moya specified Category
5e as the main data and voice cable, the standards for that cable had not yet
been finalized. Moya knew that Stanford wanted the latest in cable technology
since it's performance needed to be guaranteed for reliability for today and tomorrow's
SuperCAT360 exceeds the TIA/EIA-568B-5, Category 5e requirements and is constructed
with four balanced, bi-directional, twisted pairs within a flexible jacket,"
adds Harry van der Meer, marketing manager for Helix/HiTemp Cables (Franklin,
MA). "Not only are these cables suitable for 10 and 100 Mb/s data rates,
as required to run their network, but these cables can outperform at 1000Mb/s,
more than what Stanford presently needs today but will probably appreciate tomorrow,"
of the variations of the applications for each end user, we wanted to make sure
that there was enough voice and data connectivity to each lab and office,"
states Moya. The wallplates are double gang TSOs (Telecommunication Station Outlets)
which allow a total of a combination of up to 12 ports. In most cases two or more
were left blank for fiber and future upgrades. Typically, most of the office locations
were terminated with ten Helix/HiTemp SuperCAT360 cables - allowing 8 data connections
and two phones. However, the lab outlets mainly contained one port for voice and
five for data. "Although most locations will not utilize five data ports,
initially, we wanted to make sure that the labs were wired so that we would not
have to revisit them at a later date," states Moya.
labs and offices, were carefully designed with the most highly evolved data and
voice capabilities at all ports. "I don't think the researchers, faculty
and students will realize how much horsepower we have installed at the jack,"
Coinciding with the construction of the CCSR is an ongoing
network infrastructure upgrade project for the Medical School. This project includes
establishing a standardized wiring configuration within and between buildings
and upgrading the network equipment to service both new construction as well as
renovations. The network selected was the same as in the CCSR - a switched Ethernet
10 baseT/100baseT connection at every wallplate and gigabit Ethernet (1000 Mbps)
between the closets. To guarantee the reliability and longevity of the newly installed
systems, Leviton Telcom (Bothell, WA) and Helix/HiTemp provide a lifetime warranty
for the end-to-end cabling and connectivity. Together Helix/HiTemp's cables and
the connectivity equipment from Leviton Telcom meet the required transmission
standards set by Leviton's GigaMax program. Therefore, the channel solution from
closets to the TSOs are lifetime guaranteed through Walker Communications, who
have successfully completed Leviton Telcom's certified training program. "One
of the reasons that Stanford selected the Leviton Telcom and Helix/HiTemp solution
is because of this lifetime guarantee," states Moya.
"Standardization has to do with more than just product specification,"
states Randy Sims, Western regional manager for datacom product for Helix/HiTemp
Cables and Chromatic Technologies, Inc. (Tracy, CA). "It has to do with the
costs, warranty and keeping these authorized players consistent for long-term
relationships," he states. "Now, instead of 'a la carte cabling,' Stanford
has a sensible boilerplate infrastructure for today and all their future needs."
