Murray Teale explains. Telecommunications cabling Standards are about to undergo a generational change. Previously independent devices are being connected to the internet to allow better automation and data collection in customer premises and associated precincts. Although the delivery method is wireless, the wireless access points WAPs require communications cabling and power. This is the saving grace for telecommunications cabling: twisted-pair copper can handle both, and offer a more controlled security environment.

On the other hand, optical fibre cabling provides support for higher network speed, enhanced security and greater distance. However, it is not cost effective in delivering enough power for the operation of all active equipment.

The core can deliver higher speed data services over a greater distance than twisted pair. Consequently, the joint Australian and New Zealand Standards group CT project has been approved for the adoption of the new series. The primary changes to be adopted relate to the structure of the Standard.

All common requirements are contained in Part 1, and specific application requirements are covered in the other parts. This means that OS1 has been replaced by OS1a, which is a three window fibre. Put simply, it has optical attenuation requirements at 1,nm, 1,nm and 1,nm. As with OS2 there is no requirement to test at 1,nm. OM5 has been introduced. It has the same modal bandwidth speed as OM4 at nm and 1,nm but is designed to carry wavelength division multiplexing applications operating between nm and nm.

Two Category 8 cables and component types have been introduced. They are classified as Category 8. The introduction of Part 6 Distributed Building Services brings about a fundamental change in the deliverables of generic cabling for customer premises Standards. The new Standard looks to service connections outside the work area, typically in the ceiling space. It is aimed at supporting telecommunications, energy management, environmental controls, personnel management, personnel information and alarms.

This includes WAPs, lighting, temperature control, access control, cameras, patient monitoring and nurse call, to name just a few. Type A uses typical generic cabling presented at the device as a telecommunications outlet. The connection to a device using Type A is via patch cables. This telecommunications outlet TO is called a services outlet SO in the new Standard and is specified as a minimum of a class EA channel typically Category 6A cable and components.

Type B uses typical generic cabling that presents at consolidation points to allow for the connection of non-generic cabling. This consolidation point is called a service concentration point SCP in the Standard and is specified as a minimum performance level of a class EA channel.

The SCP can have a pigtail termination — allowing for direct termination of devices such as cameras and WAPs — or a cable connected directly to the device controller or device. There are several issues relating to the implementation of the Standard in Australia. The first is that cabling extending past the SCP is customer cabling.

The other issue relates to the connection of pigtails to the SCP. The performance Standard and associated requirements are specified only for the SCP. There are no test methods defined for the patch panel to plug in cabling that will support devices such as cameras and WAPs. Electrical connection. Contributors Technically Speaking. AS is dead; long live By Murray Teale.

Each one of these other parts has: a unique set of identifiers for distributors, consolidation points and outlets; a minimum twisted-pair performance requirement; a maximum channel length coverage ; and, its own conformance criteria. The Standard specifies two types of cabling. Previous Article PID loop tuning is our profession. Next Article Panasonic launch R32 commercial air conditioning range.

Specifies generic cabling for use within commercial premises which may comprise single or multiple buildings. It is optimized for premises having a geographical span of up to 3,m, with up to 1,,m2 of office space, and a population between 50 and 50, persons. Its principles may also be applied to installations that do not fall within this range. Cabling defined by it supports a wide range of services including voice, data, text, image and video. It specifies the structure and minimum configuration for generic cabling, implementation requirements, performance requirements for individual cabling links, and conformance requirements together with verification procedures. It provides building professionals with guidance on accommodation of cabling before specific requirements are known and it is applicable for new installations and refurbishments, and describes a flexible cabling scheme which facilitates modifications. International Classification for Standards ICS is an international classification system for technical standards.
