How to Install
UTP
(1) For reliable transmission of 100Mbps signal using UTP cables, Patch Cord, Line Cord, Patch Panel, DVO(Data
Voice Outlet), etc must meet 5 spec (Category 5 Spec.- EIA/TIA-568A).
(2) Make sure the length of patch code will be over 7m in cross-connect, If the length exceeds 7m, the length
corresponding to 90m, as much as the allowable value in Horizontal Distribution System, must be deducted.
(3) Make sure the length of line cord does not exceed 3m in line cord length. If the length exceeds 3m, as much as
the length corresponding to 90m, the allowable value in Horizontal Distribution System, must be deducted.
(4) Make sure the loose of paired pitch of UIP cable in case of disconnection to patch panel and DVD does not
exceed the following dimension.
(5) Maximum Paired Pitch – Loose : Category 5 : 13mm, Category 3 : 26mm
(6) Use jumper wires in DC cross-connect system. Then, also the loose of paired pitch must not exceed the above
standards. Especially, in case of seriously bending cables, pay attention so that damage or separation between
pairs does not happen.
(7) Maximum Curvature Diameter : 4 Pair Cable : 4 times the Diameter
Cable more than 25 Pair: 10 times the Diameter
(8) Make sure the maximum tensile force while using does not exceed 110N (11.3Kgf) based on 4 Pair
(9) Make sure jumper cables and patch codes are loosely disconnected. When tightly connected, the features of
category 5 may lower. When using Tie-wrap, make sure cables are not stressed.
(10) Make sure proper distance is maintained between EMI source and UTP cable when installing cables.
The proper distance in each case is as follows.
Conditions
Minimum Separation Distance
Less than
2.0KVA
2.5 KVA
More than
5.0KVA
In case unshielded power lines or electric facilities are open
and are in the state of being closely located nearby non-
metal pipes
127mm
305mm
610mm
In case unshielded power lines or electric facilities are in the
state of being located nearby buried metal pipes
64mm
152mm
305mm
In case buried metal pipes the power line (or the same
shields)are in the state of being located nearby buried metal
pipes
-
76mm
152mm
Notice
1) In case voltage reaches 480V and electric power source reaches more than 5KVA, separated calculation is required.
