Conclusion
This document will provide guidance to any type of education institution for the planning and
deployment of IT network infrastructures. It explores the Education environment in which IT
managers have defined business and technology objectives, the challenges they may face and
the expectations of the benefits of the solutions they are implementing. It provides
recommendations based on TE’s decades of experience in this market and investigates specific
areas of the education IT infrastructure.
2. Introduction
With many different systems and applications being deployed across the facilities, managing a
network infrastructure can be challenging. In addition to a high degree of complexity, there is
an overarching objective to reduce operational cost and boost efficiency.
3.3- Flexibility
Because of the education cycles and the diversity of disciplines, you must be able to adapt and
size your infrastructure several time during the year. The choice of your cabling infrastructure
will determine the level of flexibility that you will have. By adopting reconfigurable outlets or
plug & play solutions, you will acquire this flexibility to avoid any addition re-cabling expenses.
3.4- Security
All of us expect having our children at school in a safe environment. The integration of a
security system based on Camera, access control points, fire alarms is a mandatory investment
for schools, colleges and universities. By converging, these equipment's over IP, you will
simplify their management and will reduce the cost of operation.
An other aspect of security is to provide full access to mobile operator networks anywhere in
the facilities in case of emergency. If today, these mobile operator networks are efficient in an
open environment, it is more critical inside buildings. Solutions exist to extend these accesses
with notably Distributed Antennas Systems (DAS).

Network Equipment
With one of the industry’s broadest ranges of fiber and copper UTP and shielded products
supporting applications from 1G to 10G, TE delivers the best choice of products to suit your
specific network needs to the users.
While fiber effectively supports speeds beyond 10 and even 40 Giga, the industry is still
embracing cost-effective copper. Whereas the shielded solution offers superior noise immunity
to eliminate alien crosstalk and RFI/EMI, UTP solution utilizes superior technology to reduce
alien crosstalk noise to enhance overall performance.
Both solutions meet all requirements for Category 6A AINSI/TIA and ISO Standards.
Shielded Cat.6A solutions offer a high performance level, however Cat.6A Unshielded can be an
alternative solution in a non-sensitive background noise environment. Thanks to AirES
technology used in our XG Cat.6 UTP cables which reduce their diameter and the superior
technology used in the connectivity to reduce alien crosstalk noise, the TE’s XG Cat.6A
unshielded solution is among the most performing unshielded solution in the market.
The challenges and costs associated with network physical layer management and
maintenance are staggering—the time consuming process of tracking, analyzing and resolving
network disruptions has a direct impact on an organization’s bottom line. As the physical layer
becomes even more complex, these costs increase. While tools and software have long
enabled network and data center managers to manage switch and server ports, the passive
connections in the physical layer between the equipment and end devices have been excluded
from these systems. With the physical layer being the foundation of the entire network that all
business activities depend on, network and data center managers are now looking for ways to
effectively manage this vital infrastructure in a way that improves productivity and response
time while reducing downtime and operating expense.
Managed Connectivity solutions from TE are helping network and data center managers bridge
the gap between network management and physical layer management, transforming the
physical layer into a strategic asset and revolutionizing the way networks are managed and
controlled. By providing a real-time comprehensive picture of every connection point in the
physical layer, managed connectivity significantly improves productivity and efficiency of
physical layer management and maintenance processes while reducing costly downtime and
operating costs.
Businesses and organizations worldwide are more dependent on their physical layer than ever
before. From computers, phones and wireless devices, to alarm systems, security cameras and
video conferencing, today’s network physical layer touches virtually every device throughout
an organization. Security of the physical layer also has become a top concern among network
and data center managers, especially in healthcare, financial and mission-critical organizations
where data is required to be secure.
With 60 to 80% of unplanned downtime originating in the physical layer, the costs and time
involved with managing today’s complex infrastructures using traditional methods has taken its
toll on IT departments. Human error, security breaches and time consuming maintenance are
eating up IT budges, causing costly network downtime and increasing overall operating costs.
Network downtime for any organization is an extremely costly situation—conservatively
estimated at $42,000 per hour for the average organization, and up to $1 million or more per
hour for an e-commerce or online brokerage firm (The Gartner Group). Furthermore, while
data centers continue to house more equipment and connections, they are not necessarily
adding more staff to manage these spaces. A study by AFCOM, a data center managers group,
reports that while nearly 75% of data centers have increased their server count, 66% reduced
or maintained their data center staff. That means that most of today’s data centers are
managing more systems with same number of people or fewer.
Managing the physical layer and its every connection point via managed connectivity can help
network and data center managers confront the following issues:
• Security Every organization must mitigate the risk of network intrusion to prevent
compromise of critical business information.
• High Availability Today’s networks require uptime for business continuity, but network
and data center managers currently lack visibility of the physical layer.
• Operating Expense The high cost associated with physical layer maintenance has a
direct impact on operating expenses. Accurate knowledge of physical layer topology
leads to less network issues and faster resolution of problems.
• Compliance There are a variety of government regulations, compliance and reporting
requirements regarding how an organization’s data is accessed, transacted and stored.
Existing network management tools do not enable intrusion detection and logging of
By managing all connections and changes in the network, network and data center managers
can easily see the topology mapping and status of a connection. The time required for a
standard network MAC or
diagnosis can be cut in half,
improving meantime to response,
ensuring quality of service and
reducing operating expense. As
shown in Figure 1, TE’s managed
connectivity pays for itself within
the first two years.
Part of the portfolio of TE’s Managed Connectivity Solution, Quareo, is the only solution
available that uses connection point identification technology to track specific information
about each connector and cable in the physical layer.
Quareo utilizes microchips that are embedded in the
connectors of TE’s high-performance copper and fiber network
cabling solutions. These microchips have information related
to the cable itself, as well as unique identifiers for each
connection point in the network. Quareo can identify
everything from port location and circuit length, to polarity,
cable type, color and manufacturing information. It also is the
only solution with the capability of monitoring both the front
and rear of a patch panel. This enables monitoring cable
connections that come into the back of the patch panel, as
well as connections within the cross-connect and to the switch and servers, offering customers
the ability to trace end-to-end connections from the computer to the switch. Using a standard
form factor and footprint, Quareo solutions are easily deployed in existing fiber and copper
networks. With a comprehensive product portfolio, Quareo can accommodate both fiber and
copper applications from the simplest LAN environment, all the way to the most highly dense,
complex data center environment

TE’s Video Distribution System (VDS) enables network managers to deliver true high-definition
RF and IP video over a Category 6, 6A, or 7 twisted pair cabling infrastructure without the need
for coaxial horizontal cabling or any RF tuning.
VDS enables the delivery of video signals such as cable television, satellite, in-house video,
digital signage, electronic bulletin boards or any other service normally delivered over coaxial
system – but over a twisted pair infrastructure.
This solution is the answer to educational institutions’ needs in terms of video distribution. It
covers video requirement of any place inside schools or universities such as resting area and
dormitory.
VDS is a TIA-568/ISO 11801 compliant solution that provides these key benefits:
* Provides full RF video spectrum, along with IP video, over a single Cat 6/7 cable
* Auto adjusting RF signal eliminates the need for manual tuning
* Plug-and-play components provide ease of installation and system design/maintenance
* Head-end output is automatically adjusted for proper system operation
* Powered over cable – the remote active balun is powered over the twisted pair system
*Bi-directional signaling compatible with interactive control requirements
Because schools, colleges and universities may have long distance from one point to another,
fiber optic solutions can help overcome these challenges. Today, with Passive Optical LAN
solution, we can build an end-to-end fiber optic infrastructure, from the data center
(Equipment room) to users (Desktop or any IP devices) in a very cost effective manner.
In a POL, the OLT provides the interface between the building core router and the passive
infrastructure POL. The ONT is a device that terminates the POL and converts the signal to one
or more twisted-pair outputs to interface with the Internet protocol (IP) enabled network
devices, including IP phones, computers, card readers, cameras, Wireless access points (WAP’s)
using a standard RJ45 connection. A POL is a shared network – the OLT sends a single stream of
downstream traffic that is seen by all ONT’s. Each ONT only reads the content of those packets
that are addressed to it. Encryption is used to prevent eavesdropping on downstream traffic.
With the increasing popularity of wireless devices, mobile operators’ customers expect to have
coverage anytime and anywhere within schools, colleges or universities. This capability requires
increasing indoor network capacity across the premises.
