3 EN foreword (1 st part) Approved by CENELEC in November 2002 This European Standard, EN , supersedes both EN 50173:1995 and EN 50173:1995/A1:2000 Modify previous Category 5 and Class D specifications Define characteristics for Category 5, 6, 7 cabling components and Class D, E, F generic cabling systems Do not specify category 5E but enhance category 5 and class D parameters that are equivalent to the American TIA/EIA 5E category. Cabl-New-2003-Engl - 3 P. Nicoletti: see note pag. 2
4 EN foreword (2 nd part) Essential changes include the following: Centralized generic cabling in addition to hierarchical threelevel topology new modelling of the horizontal cabling subsystem with an optional consolidation point new modelling of the horizontal cablingsubsystem with an optional consolidation point new channel Classes E and F for balanced cabling and associated component Categories 6 and 7 classification of optical fibre cabling channels and associated component requirements limits for all channel parameters based on formulae instead of discrete values at key frequencies Cabl-New-2003-Engl - 4 P. Nicoletti: see note pag. 2
5 EN foreword (3 th part) The first edition of this European Standard had been developed to enable the application-independent precabling of office premises. Its basic principles, i however, are applicable also in various other situations including industrial premises and residential buildings Cabl-New-2003-Engl - 5 P. Nicoletti: see note pag. 2
6 EN scope This European Standard specifies generic cabling for use within premises which may comprise single or multiple buildings on a campus. It covers balanced cabling and optical fibre cabling. Safety (electrical safety and protection, fire, etc.) and electromagnetic compatibility (EMC) requirements ements are outside the scope of this European Standard and are covered by other standards and regulations. Cabl-New-2003-Engl - 6 P. Nicoletti: see note pag. 2
7 EN : applications The standard is optimised for premises in which the maximum distance over which telecommunications services have to be distributed is 2000 m. The principles of this European Standard may also be applied to larger installations. This standard contain informations and specifications usefull for generic cabling system project Cabl-New-2003-Engl - 7 P. Nicoletti: see note pag. 2

17 Dimensioning and configuring The number and type of subsystems that are included d in a generic cabling implementation depends upon: the geography and size of the campus or building; the strategy of the user. Usually there would be: one campus distributor; one building distributor per building; one floor distributor per floor. If the premises comprise only a single building which is small enough to be served by a single building distributor, there is no need for a campus backbone cabling subsystem. Cabl-New-2003-Engl - 17 P. Nicoletti: see note pag. 2
18 Dimensioning and configuring Large buildings may be served by multiple building distributors interconnected via a campus distributor. The design of the floor distributor shall ensure that the lengths of patch cords, jumpers and equipment cords are minimised and administration should ensure that the design lengths are maintained during operation. Distributors should be located such that the resulting cable lengths are not longer than: 100 m for Horizontal cabling 2000 m total path of = Horizontal cabling + building backbone + campus backbone Cabl-New-2003-Engl - 18 P. Nicoletti: see note pag. 2
19 Distribution points dimensioning and configuring There should be a minimum of one floor distributor for every 1000 m 2 of floor space reserved for offices. A minimum of one floor distributor should be provided for every floor. If floor is sparsely populated (e.g. a lobby), it is permissible ibl to serve this floor from the floor distributor ib t located on an adjacent floor If a floor area extends beyond 1000 m 2, additional floor distributors may need to be installed to more effectively service the work area. The functions of multiple distributors may be combined. For reliability reasons, redundancy may be built into a cabling design. May 2007 Cabl-New-2003-Engl - 19 P. Nicoletti: see note pag. 2

23 Work Area design The design of generic e cabling should provide for telecommunications outlets to be installed throughout the usable floor space. Telecommunications outlets may be presented singly, or in groups. Two pairs per TO may be used as an alternative ti to four pairs, however this requires pair reassignment and will not support some applications The maximum attenuation ratio of flexible cables (patch) defined as their attenuation/ insertion loss (db/100 m) compared to that of installation cables, is 1,5. Cabl-New-2003-Engl - 23 P. Nicoletti: see note pag. 2
24 Work Area design Each individual work area shall be served by a minimum of two TOs: The first outlet should be for four pair balanced cable terminated t Category 5, 6 or 7 The second outlet may be for two optical fibres terminated or four pair balanced cable terminated Category 5, 6 or 7 Each telecommunications outlet shall have a permanent means of identification that is visible to the user Devices such as baluns and impedance matching adapters, if used, shall be external to the outlet Cabl-New-2003-Engl - 24 P. Nicoletti: see note pag. 2
25 Work Area design Single user TO assembly: serves a single work area the TO assembly should be located in user-accessible locations; The performance contribution of work area cords, patch cords, jumpers and equipment cords shall be taken into account to ensure that the channel requirements (Class: A, B, C, D, or F) Cabl-New-2003-Engl - 25 P. Nicoletti: see note pag. 2
26 Work Area design Multi-user ut use TO assembly (MUTO)in an open office environment, a single assembly of TOs may be used to serve more than one work area: Shall be located in an open work area so that each furniture cluster is served by at least one multi-user TO assembly Should be limited to serving a maximum of 12 work areas Should be located in user accessible,,permanent locations Shall not be installed in ceiling spaces or any obstructed areas The performance contribution of work area cords, patch cords, jumpers and equipment cords shall be taken into account to ensure that the channel requirements Cabl-New-2003-Engl - 26 P. Nicoletti: see note pag. 2
27 Consolidation Point Connection point in the horizontal cabling subsystem between a floor distributor and a telecommunications outlet. The installation of a consolidation point in the horizontal cabling between the floor distributor and the telecommunications outlet may be useful in an open office environment where the flexibility of relocating TOs in the work area is required. Like open-space where consolidation point act as a a Multi- User Telecommunication Outlet (MUTO) One consolidation point is permitted between a FD and any TO. Cabl-New-2003-Engl - 27 P. Nicoletti: see note pag. 2
28 Consolidation Point In addition, where a consolidation point is used: shall be located so that each work area group is served by at least one consolidation point; should be limited to serving a maximum of 12 work areas; should be located in accessible permanent locations such as ceiling voids and under floors; for balanced cabling, the effect of multiple connections in close proximity on transmission performance should be taken into consideration when planning the cable lengths between the floor distributor and the consolidation point; a consolidation point has labelling and documentation requirements and shall be covered in the cabling administration system. Cabl-New-2003-Engl - 28 P. Nicoletti: see note pag. 2
29 Horizontal cabling design The selection of balanced cabling components will be determined by the class of applications to be supported by the cabling: Category 5 components provide Class D balanced cabling performance; Category 6 components provide Class E balanced cabling performance; Category 7 components provide Class F balanced cabling performance. Cables and connections of different categories may be mixed within a channel however the resultant cabling performance will be determined by the category of the lowest performing component. Cabl-New-2003-Engl - 29 P. Nicoletti: see note pag. 2

Ratio of flexible cable attenuation (db/m) to fixed horizontal cable attenuation (db/m) Ratio of CP cable attenuation (db/m) to fixed horizontal cable attenuation (db/m) (a) This length reduction is to provide an allocated margin to accommodate insertion loss deviation. For operating temperatures above 20 C, H should be reduced by 0,2% per C for screened cables and 0,4% per C (20 C to 40 C) and 0,6% per C (> 40 C to 60 C) for unscreened cables. Cabl-New-2003-Engl - 36 P. Nicoletti: see note pag. 2
37 General restrictions for horizontal cabling design May 2007 The following general restrictions apply: the physical length of the channel shall not exceed 100 m the physical length of the fixed horizontal cable shall not exceed 90 m and may be less depending on the length of CP cables and cords used and the number of connections; where a multi-user TO assembly is used, the length of the work area cord should not exceed 20 m; when used, a CP should be located at least 15 m from the floor distributor in order to reduce the effect of multiple connections in close proximity on NEXT and return loss; the length of patch cords or jumpers shall not exceed 5 m.
