DATA CA BLES 64 GEN ERAL GE NE RIC CAB LING SYS TEMS Generic cabling is applied to telecommunication cabling as a permanent part of the office to meet the expanding needs of the user’s. It meets also the future data transmission requirements including new computers and relocation of the workstations on the premises - minimizing the need for new cabling. The physical structure of a generic cabling system is star-shaped. This makes the network control easier which is important especially now when the telecommunication and data networks in buildings are the property of the owner. A star-shape cable system allows to change the network topology from the cross-connection to a bus or a ring. In a star-shape system all the active components can be placed together in one space which is easy to control and can be locked and which improves data security. Also measurements and maintenance are easier to carry out in the cross-connection area. lf one branch of the star network falls off the whole system is not paralyzed because the faulty branch can be disconnected from the network. The generic cabling system is not really open until its components are vendorindependent. They just have to conform to the standards. When planning a cable system it is important to consider what the openness really means and how open the non-compatible and vendor-dependent cable systems are. STAN DARDS The European standard for the generic cabling systems is EN 50173 which was set up on the basis of the international ISO/IEC 11801. The corresponding standard in the U.S. is ANSI/TIA/EIA 568-A supported by TIA and EIA. The EN 50173 applicable in Europe defines the different transmission line applications and classes as well as the categories 3 and 5 for the line components. For example, a data network that fulfills the requirements of class D can be set up from components of category 5. EN 50173 recommends the use of 100 Ω twisted-pair cables in horizontal cabling. Cat. 6 standard will be ready in 2001. SCREENING The abbreviations UTP, FTP and STP-screening construction are used to refer to the cable. UTP is a cable where symmetrical twisted pairs are used for screening. A FTP cable has an overall metal shield, and in a STP cable all the pairs are screened separately. The cable type is chosen to suit the environment where it’s used. In Finland most of the installations are made with FTP and UTP cables. Optical fibre cables are recommended for local and rising cabling. The STP may also be marked ScTP and S/STP, meaning a construction with a pair and an overall shield.

REC OM MEN DA TIONS — It is important to examine the building needs very carefully, including e.g. the existing network and the desires for more extended data transmission in the future. — The maximum length of horizontal cabling is 90 m. The maximum length of cross-connection and equipment cabling is 10 m. — An optical fibre cable is recommended for local and rising cabling. — Two double cables should be installed for each work area, in order to meet the increasing need of telecommunication. DATA TRANSMISSION CABLES Our complete range of UC cables fulfills tomorrow’s needs. Our new product family UC 400 is designed for applications beyond CAT 5 with good properties. Our new development for the high-end field is UC 1000. A cable class that not only fulfills the above mentioned standards, but also offers reserves, allowing base band transmission of Gigabit-Ethernet. _
