Fibre Optic Cabling
Optical fibre solutions can provide unparalleled speed and transmission rates for your business network. Fibre overcomes many of the issues that traditional communication cables face. As well as being a faster method of transferring data, it is not restricted to a maximum of 100 meters in length like copper cables. This means it’s easier to create networks even when distance is an issue. With the Nation Broadband Network (NBN) rolling out fibre networks to premises across the country it is the way of the future.
structured cabling systems
Fibre is a common component within a structured cabling system. Typically, it interconnects communications infrastructure such as equipment cabinets, cross-connects and consolidation points (nodes). In this role, the fibre optic cabling is referred to as backbone cabling. Fibre is usually used where distances between nodes is greater than the 100m maximum for copper based solutions.
Fibre optic cables are usually multicore, with a single core being used for transmission in one direction only. Therefore for bi-directional communication, two cores are required.
Fibre optic cables are usually one of two possible types;
Two popular sizes of multimode fiber exist today for use in commercial applications: 50 micron and 62.5 micron. Each has a common cladding diameter (125 microns), but different core diameters (50 microns and 62.5 microns). Several standards address both sizes to varying degrees of depth. ANSI/TIA/EIA-492-AAAA and ANSI/TIA/EIA-492-AAAB are two popular sources of information. Either provides all of the necessary details for complete fiber.
However, you must add the optical performance level (attenuation and bandwidth). There are a number of standards you can reference to cover the optical performance aspects of the specification. The most well-known standard today is IEEE 802.3z for Gigabit Ethernet. The Table, above, compares several specifications of international standards.
There is, however, one area in which the standards fall short of fully encompassing all the characteristics of a multimode fiber. Fiber manufacturers have responded by developing alternate measurements and product guarantees to fill the void. The resulting laser-optimized fibers show superior performance in laser-based systems. They are currently offered as a performance option not covered by standards, and they must be addressed separately in a user specification. Lasers are proving to be better light sources than LEDs, which are traditionally used with multimode fiber. As their prices fall and their performance improves, lasers are gaining wider acceptance.
Recent advances have increased single-mode fiber versatility. The introduction of the erbium doped fiber amplifier has extended long-haul (cross-country, not local links) system reach, and technologies for dense wavelength division multiplexing have led to the introduction of new fiber types for single-mode applications. Nearly all long distance telephone, Internet, and cable-TV links use single-mode fiber.
With demand increasing for bandwidth on data networks and LANs, single-mode fiber is becoming steadily more popular in new applications. Many installations include multimode fiber for current systems and single-mode fiber in the event of future expansion — sometimes in the same cable. In these cases, the multimode fibers are terminated for immediate use, and the single-mode fibers are coiled, taped, and left for future use.
Standard single-mode fiber was introduced to the commercial telephony market in 1983. While dimensional tolerances and optical performance have improved over the years, the design of single-mode fiber has, for the most part, remained the same. In the 1990s, LAN standards began to include options for standard single-mode fiber. To distinguish it from some of the newer specialized fibers, older versions of single-mode are referred to as dispersion-unshifted single-mode fiber. Just as for multimode, a national standard enumerates all the requirements for this type of fiber. ANSI/TIA/EIA-492-CAAA includes all of the details necessary to specify this type of fiber, as well as several additional optical performance options.

national broadband network
The National Broadband Network (NBN) has been designed primarily around the Fibre-to-the-Premise (FTTP) topology. By approximately 2022 fibre will ultimately replace copper cabling run to many residential and commercial premise across Australia. Regardless of the type of connection employed (fibre, wireless, satellite), cabling within the premises will remain copper-based.

structured cabling systems
In general terms, structured cabling systems (SCS) reticulate data and voice services around the office over communications grade cable. This means that any outlet can be a phone point, or a data point. The change is made simply with patching within a centrally located equipment cabinet, which is usually where active switching equipment, telephone systems and servers are also located. Structured cabling systems have the benefits of making adds, moves and changes as the business develops extremely easy, whilst also being able to be done in-house without the need for specialist technicians. A SCS is also a base starting point for implementation of Voice over IP (VoIP) telephony services.
