owhere is that reflected more than
in Fran Towey’s personal account
on page 4 of how the team at KRONE
Americas pitched in to help their
customer, Verizon Commun-ications,
after the September 11 tragedy in New
York city.
Verizon’s loyalty to the use of KRONE
products stems back to 1992 when
KRONE products survived major storm
flooding in Wall Street, resulting in the
telecomunications giant standardising
on our product. Again, we came to the
rescue with support and service after
the 1993 World Trade Centre bombing left
Verizon with more outages.
KRONE Australia has often been asked to help
out our customers in emergencies - whether
they are fire, flood, network failures or other
incidents. One of the most dramatic examples
was in January, 1995, when our subsidiary office
in Tokyo was called on to help Japan’s telco, NTT,
after the traumatic Great Hanshin earthquake
devastated the people and environment of

Kobe. In the midst of destruction, the KRONE
LSA-PLUS products installed in Kobe withstood
the violent shaking of the earthquake. With
these network foundations still in place, KRONE
was able to work with authorities to help
corporations re-establish their communications
with a minimum of fuss.
We continue to use the same LSA-PLUS core
technology today - the difference being that our
products are constantly evolving to meet the
increases in bandwidth demanded by our
customers.
Club KRONE was established in 1998 to add
value to the products and solutions we provide to
our installer customers and Peter Davis tells how
we have enhanced the Club’s offerings in 2002.
See how our end-user customers, Deakin
University and Westinghouse Signals, have
benefited from the solutions we have developed
for their particular needs.
We make it our business to keep our
customers informed by issuing regular updates
on industry regulations and standards via
Network News, Club KRONE or our website.
KRONE’s training courses offer certification in
structured cabling and optical fibre as well as
more advanced programs for Master Cabler and
Master Designer qualifications.
To enhance our productivity so we can provide
better service for our customers we have made a

significant investment in a new Cisco IP
telephony system. It will be business as usual
during the changeover in February - see Rob
Milne’s article on page 15 for more details.
If you have problem and need a solution, call
us. It’s all part of the service.
Sincerely ...
Craig Jones
CEO

e are committed to providing incentives
and information that will enable our
KRONE installers to build their businesses and
better service their customers.
Right from the start, the programme was
unique to the industry in that it is not a lottery:
the day members start spending is the day they
start to benefit.
Installers simply purchase KRONE voice and
data products from any of KRONE’s authorised
distribution outlets around Australia to begin to
acquire Club KRONE points.
The products or bonuses given on redemption

of points are relevant to our customer’s business,
not token gestures to store on the mantelpiece.
Past promotions offered bonus KRONE product
and points also could be redeemed against
KRONE training sessions.
Distributors have also benefited substantially
from the scheme, enjoying new business
opportunities as more installers have become
involved.
Last year we launched the Club KRONE
website and, in a recent survey, all members
were aware of the website with the majority
visiting the site regularly.
More and more, we are seeing members use
the website to redeem points. “ It makes life so
much easier,” says Pat Dillon of Bendigo Voice
and Data. “ I don’t have to calculate how many
points I have left. The system simply recalculates
as I mark off the selected items.”
One of the most significant benefits for
KRONE is that the Club enhances our
relationship with members enabling us to gain
valuable feedback, which we apply when
developing new products or reviewing our Club
KRONE offerings.
We have applied this information to
redesigning the Club KRONE website. The new
format for 2002 makes it easier to use and
incorporates a host of additional benefits such as
the Frequently Asked Questions section, or the

Cablers’ Forum which enables you to post or
reply to questions about KRONE products and
any other communications-related topics (see
more features on page 16).
Let us know what you think and, if you’re not
a member - or your membership is inactive, now
is the time to move.
COME AND VISIT OUR
MANUFACTURING FACILITY
One of the unique benefits of purchasing
KRONE product is the surety of supply, product
functionality and quality, R&D, logistics and
environmental factors. For 20 years we have
been the only telecommunications connectivity
manufacturer located in Australia.
Some of you have already visited our plant at
Berkeley Vale on the NSW Central Coast. It’s
impressive and we’re proud of it and the industry
awards we have won. For those who haven’t
been our guests for a factory tour because of
time and work constraints, we thought we’d
take you on a virtual tour starting on page 6. 

FOR THE BEST RESULTS
It’s four years since we introduced Club KRONE and it has proved a
boon for our active members. We started with a handful of active
members in 1998 and it’s gratifying to see that figure has grown well
beyond our expectations.
Distributors have also benefited
substantially from the scheme,
enjoying new business
opportunities as more installers

esign of backbone cabling is often in the
shadow of horizontal cable design, but the
need for reliable high speed data transmission will
bring backbone design to the fore. Changes to
cabling standard AS/NZS 3080 later this year will
show a structured approach to backbone lengths.
The physical topology of the backbone cabling
will remain as the current Star topology, but the
backbone channel lengths and the class of
application to be supported will determine the
selection of balanced hardware components.
The backbone channel, either building or
campus, is deemed to contain a cross-connect at
each end and, so, represents the maximum four-
connector configuration for class D, E, or F as a
backbone (as opposed to a horizontal channel).

The backbone channel includes additional
cords comprising patch cord/jumpers and
equipment cords. The assumptions are that:
1. the flexible cable within these cords may have
a higher insertion loss than that for solid cable
used in the backbone; and
2. all the cords in the channel have a common
insertion loss specification.
In order to accommodate the higher insertion loss
of the patch cords/ jumpers, and equipment cords;
the length of backbone links must be reduced
according to the class of backbone link and the
category of components used to make up the link.
Additionally, two general restrictions apply:
1. the physical length shall not exceed 100 metres
for Class D, E, and F backbone channels; and
2. when four connections are used in the
channel, the minimum backbone link should be
15 metres.
The maximum length of backbone channels
will depend on the total length of cord to be
supported within the channel. The maximum
lengths of cord shall be set during the design
phase and a management system is required to
ensure that these lengths are not exceeded
during the subsequent operation of the cabling
system after initial installation.
However, where channels contain more or less
than four connectors, the backbone length must
be reduced (where more connectors exist) or

may be increased (where less connectors exist)
by two metres per connector for category 5E
components and one metre per connector for
category 6 and 7 components. Also, for
operating temperatures above 20°C, backbone
link lengths should be reduced by 0.4% per °C
for UTP cables.
The way to achieve maximum length and
maximum performance out of your backbone
design is to reduce insertion loss by (a) the use of
HIGHBAND modules at each end and (b) by the
use of KRONE Patch By Exception (PBE)
methodology. The table of backbone link lengths
(see below), shows that the length must be
reduced by a factor of x, dependant on the
combined lengths of patch/jumper and
equipment cords, and the use of stranded
cordage. Using KRONE’s PBE and factory-tested
LAN leads for equipment cords mean that X=0
and no de-rating of length is necessary.
Take the opportunity to update your skills
and knowledge, by undertaking a KRONE
Training Course. For details, visit our website
at www.krone.com.au and look under the
Training section. 

enerally, in today’s installations copper is
used for horizontal distribution and fibre
connects the closets to the main equipment
room. Clearly, this makes sense given the high
bandwidth available in fibre and its smaller size
(which enables easy routing between closets).
Because backbone capacity should be greater
than desktop capacity, and since desktops have
only recently been making the wholesale switch
to 100BASE-T, the migration to a fibre Gigabit
Ethernet backbone is on the horizon. As 1000
BASE-T to the desktop becomes widespread, the
next natural progression will be to a 10Gbps
fibre backbone. In fact, at this stage, fibre is the
only cabling medium recognised in the draft
standard for 10Gbps Ethernet.
‘FIBRE TO THE ZONE’ AND BEYOND
The growth in demand for more bandwidth will
see fibre deployed out to particular zones (or
departments) within the building with copper
running from the zone to the desktop. A key
factor in this scenario is the capability to
remotely manage switched hubs (switches); no
longer will IT personnel need to physically check
each port in each closet.
The Fibre to the Zone configuration enables
the network manager to place active devices

closer to the users - either to smaller,
intermediate telecom closets or even to small,
lockable enclosures near the workgroup. Since
switches are now available with fibre uplinks
and
copper ports, it may be that one device will
suffice per workgroup.
This strategy works especially well for large,
open office cubicle groups or for very large work
areas that have poorly spaced telecom closets.
Fibre to the Zone also is relatively cost-effective
since traffic back to the main closet is
aggregated over just two fibres. In fact, utilising
just two fibres from the zone consolidation point
would eliminate the need to run an individual
copper link from each workstation to the closet.
If, in the future, the client decides to
implement fibre-to-the-desk (FTTD) there will
already be a fibre backbone out to the
workstation zone. Replacing the short runs to
the zone enclosure will be far easier and more
cost effective than replacing entire copper links
back to the closet to implement FTTD.
We anticipate the deployment of these fibre-
extending strategies to be sporadic due to cost
factors. An all-fibre network (FTTD) is the most
expensive alternative because of the higher cost
of fibre network interface cards (NICs) and
optical switch ports. On the other hand, Fibre to
the Zone costs are lower than FTTD because of

the utilisation of copper hub ports and NICs.
Fibre to the Zone puts companies one step
closer to the ultimate upgrade: Fibre to the
Desktop. Copper, however, is well and truly the
preferred medium for horizontal structured
cabling installations.
Personally, I do not see this changing in the
very near future until the cost of fibre cabling
and connectivity reduces to the level of a copper
solution. By then, copper may well be supporting
10 gigabits. 
