The length of the fixed cable between the jack and the patch panel
is set at a maximum of 90 m here.
The maximum distance in the Permanent Link can also be shorter,
since a consolidation point integrated into the cabling runs also
has effects on the technical transmission values of the laid cable.
Patch cables between jack and end device should not exceed a
maximum length of 20 m: the length of patch cable used in the
patch field at the floor sub-distribution cable has a maximum
length of 5 m. Consolidation points which are used should be
placed at least 15 m from the floor sub-distribution panel since
plug-in connections used in the immediate vicinity can exert influ -
ences on various transmission parameters. The types of cable
used in cabling on floors consist of 100 Ohm 4 paired twisted pair
cables and 50/125μ multi-mode glass fiber cables.
The maximum cable length of the transmission run should be
2000m for the site and building cabling of the secondary area.
The previously mentioned cable types are also preferred here. The
often larger distances between buildings also offer an area of use
for 07/15μ mono-mode glass fiber cable.
Connection technology for structured cabling
The cable which has been used for laying can be described with
the following, different characteristics.
? Copper conductor consisting of solid copper for permanent
installation between sub-distribution panels on floors and
between distribution panels and jacks.
? Copper conductor as flexible conductor wire for use in the
manufacture of patch cables.
? Details of the diameter and/or cross section in mm, mm2 or
AWG (American Wire Gauge). The larger the wire diameter,
the smaller the attenuation.
This section shows the following examples:
AWG 24/1 = conductor consisting of solid wire with 0.511 mm
conductor diameter
AWG 26/7 = conductor consists of 7 wires with 0.48 mm
conductor diameter
? Strands are twisted into pairs and provided with a colour code
in the conductor insulation. The colour code is done according
to EIA/TIA 568 / IEC 708-1 with the wiring:
Pair 1 = wire 1 in white/blue, wire 2 in blue
Pair 2 = wire 1 in white / orange, wire 2 in orange
Pair 3 = wire 1 in white / green, wire 2 in green
Pair 4 = wire 1 in white / brown, wire 2 in brown
? The screening is used to improve transmission safety. In
accordance with the valid standard, it guarantees the limita
tion of electromagnetic disturbances and also the immunity of
the network against disturbances.
UTP completely unscreened, paired unscreened,
twisted cable
F/UTP completely foil screened, paired unscreened, twisted
cable
SF/UTP cable completely screened with foil and braid, paired
unscreened, twisted cable
S/FTP cable completely screened with braid, paired foil
screened twisted cable
? External cladding consisting of PVC or a halogen-free, fame
resistant compound.
Halogen-free = no corrosive, or clearly less toxic gases and
very low quantities of smoke
Flame resistant = self extinguishing after removal of the heat
source, very limited propagation of fire
FR = flame retardant
LS = low smoke
NC = no corrosive fumes
OH, ZH = no halogen
The requirements for the patch panels and jacks are defined in
DIN EN 50173-1. These products are divided into various classes
in accordance with the performance class. Optimisation of the
products allows panels and jacks to satisfy the requirements when
a gigabit Ethernet is being operated. These have been set down
in the standards DIN EN 50173-1:2000 with both types, category
3 up to 16 MHz and category 5 up to 100 MHz and also in EIN EN
50173:2002 with the types, category5 up to 100 MHz, category 6
up to 250 MHz and category 7 up to 600 MHz. The designation,
category 5E which is generally used on the market corresponds to
category 5 in accordance with DIN EN 50173-1:2000.
All the category 5 products certified according to standard can be
used independently from their manufacturers in so-called ?Mix &
Match" systems. They are combined into a class D connection in
the installation which has been created.
Class E products are characterized by the fact that each manufac -
turer has optimized his articles for his products with 250 MHz in
order to satisfy the requirements of class E.
All the products are clearly defined and only ?work" with each
other according to certification. This means that ?Mix & Match" is
not possible. These products also do not comply with category 6 in
accordance with DIN EN 50173-1:2002.
Category 6 products according to the new standard are only
products which have been tested according to ?De-Embedded
Testing". This makes sure that the advantages reached by techni -
cal and mechanical improvements are used. Each category 6 jack
with a RJ45 plug produces a category 6 connection according to
standard.
