Planning and implementing a premise cabling system according TIA 568, IS 11801 or EN 50173-1 following points should be covered: The links have to fullfill at least Category 5E / Class D requirements. Dedicated separate phone cablingsystems are removed. The number of ports planned in the past for ISDN or analogue phones should be added to the LAN infrastructure in the future. VoIP phones require same as personal computers an Ethernet connection with 10 or 100 Mbit/s that at least category 5 components (cable, panels, outlets and cords) are required. Practical experience shows three ports per desk cover most of the demand in various scenarios. The main difference to the past is that instead of planning two Ethernet ports and one ISDN port three Ethernet ports should be installed in the future.
From the very beginning of the digital data era, we have fulfilled data networking requirements for both the short term and the far future by using great innovation and a forward-looking ap- proach. The profound expertise of the Infrastructure & Datacom BU in copper and fiber optical cabling technologies represents a powerful advantage in structured cablingsystems for industry, data centres and offices – the sustainable copper and glass fiber cables of our own production are among the safest and most innovative products in the primary to tertiary cabling market.
The scalability of Ethernet technology allows the constant expansion of the networks used for information engineering in buildings. In banks and insurance companies, research and development, univer- sities, hospitals, hotels, airports and many other ﬁ elds of application, high-performance, highly available Ethernet networks are indis- pensable for smooth operation and economic success. Besides the economically sound networking of PCs and printers, the intelligent combination of ﬁ bre optic technology in the backbone and copper technology up to the user allows IP telephony too. In addition, Power over Ethernet supplies terminal equipment such as WEB cameras, WLAN access points, IP telephones and notebooks with electricity and voltage – all via the structured copper cabling!
Work with a partner to create a list of questions you should ask a client who has hired you to build a network. The client wants to know which type of cable you plan to use and why, how much the cable will cost, and why you selected the particular topology. The client also wants you to submit a proposal that defends your choice of cabling and network design. After you create your questionnaire, role-play with your partner. One of you will assume the role of client, and the other the role of the network designer. The client will answer all the questions for a fictitious company of his/her choice. The network designer will record all of the answers. When the questionnaire is complete, you will both analyze the
The majority of structured cabling specified for new buildings in the past 5 years has been category 6/class E rated because it provided the maximum performance headroom and return-on-investment. Category 6/class E cabling delivered double the signal-to noise margin (attenuation-to-crosstalk margin is positive to 200 MHz) of category 5e/class D cabling and provided the performance headroom desired by end-users to ensure that their cabling plant could withstand the rigors of the cabling environment and still support 1000BASE-T when it was time for an application upgrade. The category 6/class E cabling specification development process also brought to light the need to limit the conversion of differential mode signals to common mode signals and vice versa through the characterization of component balance, resulting in cablingsystems with improved electromagnetic compatibility (EMC) performance.
The scattering parameter is a widely used tool for transmission line network behavior analysis and design. It also offers flexibility in design and can be used to analyze cascaded cables performance as in .However, the 40GBASE-T system is proposed to consist of two connectors that have effects on the overall loss, coupled with the insertion loss deviation due to the channel. Therefore, there is the need to model and factor them into the channel insertion loss using the scattering parameter which presently does not have express provision for it.The 40GBASE-T is the next Ethernet standard for 40 Gigabits/second over copper twisted-pair cabling. The Telecommunication Industry Standard (TIA) is developing specifications for category 8 cablingsystems suitable for 40GBASE-T.The International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) also has a similar project that aims to define two variants of cablingsystems that will support 40GBASE-T.

Achievable SNR margin is dependent upon the combined properties of cabling balance and the common mode and differ- ential mode noise immunity provided by screens and shields. Applications rely on positive SNR margin to ensure proper sig- nal transmission and minimum BER. With the emergence of 10GBASE-T, it’s become clear that the noise isolation provided by good balance alone is just barely sufficient to support transmission objectives. The alien crosstalk and noise immunity benefits provided by F/UTP and S/FTP cabling designs have been demonstrated to offer almost double the Shannon capac- ity and this performance advantage has caught the attention of application developers and system specifiers. It’s often said that the telecommunications industry has come full circle in the specification of its preferred media type. In actuality, today’s screened and fully-shielded cablingsystems represent a fusion of best features of the last two generations of LAN cabling: excellent balance to protect against low frequency interference and shielding to protect against high frequency interference.

• All cabling work conducted is consistent with regulatory and legislative obligations including relevant Australian and Western Australian Standards; • All relevant stakeholders are consulted prior to commencing cabling projects; • Comprehensive audits are conducted on completion of cabling projects; • Only cablingsystems offering appropriate warranties are used;
One strategy for reaching outlying devices is to ensure that a network telecommunications room (TR) is always within 100 metres of every device, which requires proper planning and design. Unfortunately, implementing a TR within 100 metres of every door lock, thermostat, or camera is not always the most cost-effective option. Telecommunications space is expensive, and having several TRs spread throughout a facility means IT personnel have more decentralised spaces to manage. Extending the reach to outlying and remote devices located at distances greater than 100 metres from the TR can be easily accomplished with the use of fibre optic cabling and media conversion technology. Fibre optic cabling supports transmission of data to distances of 550 metres or more, depending on the application and fibre type. The use of media conversion at both ends of a fibre link is a cost-effective method for converting electrical signals to optical signals at the device and back to an electrical signal at the TR.
It is interesting, not to say unnerving, that the characterisation of cabling in support of 10GBASE-T has to address, for the first time, the issue of alien crosstalk – the electromagnetic interference between adjacent cables (“inter-element crosstalk” for optical fibre). Models used to determine the viability of 10GBASE-T determined that the control of alien crosstalk is “mission critical” since random signals originating external to the channel cannot be cancelled by the digital signal processing. A variety of means may deliver alien crosstalk control including the use of physical mitigation techniques (randomising cable lays) or electromagnetic mitigation techniques (screening). One thing us for sure, it is going to be virtually impossible to measure on an installed system. The number of connections in the 10GBASE-T channel will still be limited to four and alien crosstalk will be a key concern at those panel connections.
The use of the PROFINET Installation Guideline for Cabling and Assembly may involve handling hazardous materials or tools or involve dangerous work. Due to the many and diverse applications of PROFINET, it is not possible to take all options or safety requirements into consideration. Each application makes different demands on the installer. In order to competently judge possible dangers, you must inform yourself about the safety requirements of the respective system before starting your work. Special attention must be paid to the laws and regulations of the respective country in which the system will be operated. You shall also observe general health and safety requirements, as well as the requirements of the company for which the system is being installed. In addition the manufacturer supplied documentation for the PROFINET components used must be considered.

Any failure due to defective material, equipment, installation, or workmanship that may develop shall be corrected at no expense to the Owner, including all materials, labor, travel, expenses, system diagnostics, and damage to areas, materials, and other systems resulting from such failures.
In the analog video world, type and quality of twisted pair cabling was never a major concern. Installers could visit their local hardware store and pick up a spool of the cheapest CAT 5E cable available to achieve success. Sure, the need for low skew twisted pair cabling was always there, but for the majority of AV installs (which tend to be under 300’), even that was not always necessary. The problem is that AV integrators got used to the connotation of “I’ll just run CAT 5.”
