Cable Sharing Helps Offset the Effect of Rising Copper Prices on Network Infrastructure

According to the London Metal Exchange (LME), the price of copper has tripled in the past four years, rising over 59% between January and May of 2006 alone. With copper prices soaring globally and showing little signs of stabilizing, network cabling companies have been forced to adjust copper cable pricing accordingly.

"Enterprises are facing difficult network infrastructure decisions." explains Bob Carlson, Siemon's VP of Global Marketing, "It is a well-established best-practice to install a future-proof cabling plant capable of supporting the next generation of application speeds. The total cost of ownership on 10Gb/s capable cabling is far better than lower performing options. While these full-lifecycle savings hold true even with increasing copper prices, the up-front costs can act as a deterrent."

Enterprises are under pressure to balance long-term costs with current expenditures. Rising copper prices have led some to explore fibre to the desk alternatives. Although fibre can provide a future-proof option, it is not capable of supporting the growing demand for Power over Ethernet applications, and the cost of fibre electronics remains prohibitively high for horizontal applications.

Fully-shielded (S/FTP) category 7/class F copper cabling, such as Siemon's TERA®, is capable of supporting application speeds well beyond 10 Gb/s. This future-proof performance provides an extended cabling lifecycle, driving the total cost of ownership (TCO) well below that of category 5e, category 6 and even category 6A UTP.

While long-term savings and performance capabilities beyond 10 Gb/s are driving global adoption of the TERA system, its unique cable-sharing ability in support of lower speed applications can provide up-front savings through the reduction of cable counts. By combining the use of one TERA outlet dedicated for high-speed applications and another for cable sharing of lower speed voice and video applications, end-users simultaneously benefit from the highest performing and most cost effective copper solution.

Accepted by both TIA and ISO, cable sharing describes the practice of running more than one application over different pairs of a twisted-pair copper telecommunications channel. In the case of category 7/class F TERA, up to four applications can be supported with a single cable. This ability is a function of both cable and outlet construction.

By virtue of individually foil-wrapped pairs and overall screen, S/FTP cable exhibits excellent internal, pair-to-pair crosstalk control. This allows separate applications to run without interference from others within the same sheath. The cable construction is further supported by the TERA 4-quandrant isolated outlet, the only non-RJ category 7 interface recognized by ISO/IEC.

Fitting within a standard RJ footprint, the combination of the TERA outlet and cord options allows extremely simple facilitation of cable sharing. As with traditional cabling channels, all four pairs of each cable are terminated in a single outlet. However, unlike an RJ interface, the TERA outlet can support up to 4 one-pair cords, 2 two-pair cords or a combination of the two, without the need for additional splitters or adapters. Using these features, many popular applications may be converged onto a single cable:

  • Analog Voice, 1 pair
  • VoIP, 2 pair
  • Video over IP, 2 pair
  • CATV, 1 pair
  • CCTV, 1 pair
  • 10/100BASE-T, 2 pair

Depending on the applications supported, a single TERA cable can replace up to 4 copper channels. With copper prices significantly raising the cost of cable, this reduction in total cable runs can provide an immediate cost benefit.
