Future Proof

Residential cabling is growing more and more popular by the day.

We take on a partnering roll with the end users of the structured cabling. The end users understand a lot more about cabling than they did 10 years ago.

We help find solutions to their needs.

We let them know that our cable is not assurance of the future, it's planned for the future based on an educated decision we make knowing what's coming down the line.

We use the phrase “Future Planning”instead of Future proof.

Would you ever consider building a home…

Without Plumbing?

Without a Telephone?

 Without Electrical Wiring?

Not too long ago, homes were built without utilities such as plumbing, electricity, and telephones. One reason was because the technology had not yet been developed. Another reason was the infrastructure to support these functions wasn't in place in the residential arena--it was first installed in the cities or manufacturing locations. What good did it do to install pipes in a house if there was not a sewer or septic system in the neighborhood? Electrical wiring could be run throughout the house; however, it wouldn't work without an energy source. Similarly, telephones only worked if a pole was mounted outside your house to carry the line back to the central office. The residential infrastructure to support these services had to be put in place before plumbing, electricity, and telephones could be installed in a home. Once the infrastructure was there, virtually no one would buy a home without them.

Now in the new millennium, technologies that first became commonplace in the industrial setting are again shifting into the residential setting. High speed internet service, energy management, security systems, home networking, and distributed audio are just a few of the technologies the homebuyer wants in their home, or at a minimum, be able to easily obtain or upgrade to in the future. Forecasters predict residential cabling is expected to grow 55% annually in the next two years.

Now is the time to start”Future Planning” your new business or residence.

Just What Is Structured About Structured Cabling?

Structured cabling design and installation is governed by a set of standards that determine how to wire a data center, office or apartment building for data or voice communications, using Category 5(CAT 5E) or Category 6 cable(CAT 6E) and modular sockets. These standards define how to lay the twisted pair in a star formation, such that all outlets terminate at a central patch panel (which is normally), from where it can be determined exactly how these connections will be used. Each outlet can be 'patched' into a data network switch (normally also rack mounted alongside), or patched into a 'telecoms patch panel' which forms a bridge into a private branch exchange(PBX) telephone system, thus making the connection a voice port.

Lines patched as data ports into a network switch require simple straight-through patch cables at the other end to connect a computer. Voice patches to PBXs in most countries require an adapter at the remote end to translate the configuration on 8P8C modular connectors into the local standard telephone wall socket. In the U.S., no adapter is needed, as the 6P6C plug used with RJ11 telephone connections is physically compatible with the larger 8P8C socket and the wiring of the 8P8C is compatible with RJ11. In the UK, an adapter must be present at the remote end as the is physically incompatible with 8P8C.

It is normal to see different colour patch cables used in the patch panel to help identify which type of connection is being carried, though the structured cabling standards do not require this, except in the demarcation wall field.

Cabling standards demand that all eight connectors in Cat5/5e/6 cable are connected, resisting the tempation to 'double-up' or use one cable for both voice and data. This is generally a good thing as it means that they fully support features such as Power over Ethernet which require the so-far unused brown cables.

Here are some basic questions you may be asking yourself if you have never installed a structured cabling system before.

What are 'The standards' ? There are three main cabling standards:
  • EIA/TIA 568A - This is the American standard and was the first to be published (1991).
  • ISO/IEC 11801 - The International standard for structured cabling systems.

Plainly, the bandwidth of such a system directly limits the data rate, but in theory it need not. Consider a protocol which uses "frequency shift keying" instead. Here, two different frequencies (both of them within the legal bandwidth) are used to represent 1 and 0. The maximum data rate is now the maximum speed at which you can shift between the two frequencies. This is still limited by the bandwidth, but not so directly - the resulting maximum data rate is higher. And what happens if you use more than two frequencies? You can then transmit more than one bit of information per signal transition, upping the data rate again without increasing the maximum frequency of the signal.

It is techniques such as these which have allowed the development of 56k modems. Using a combination of multiple-level amplitude, frequency and phase modulation, they manage to extract up to 56,000 bits per second of performance from the aforementioned 2.7 kHz bandwidth. To achieve this using plain 2-level ASK would require a bandwidth of hundreds of kilohertz.

"Baud rate", strictly, is a measure of "signal elements" per second, and is not a useful measure where the above signalling techniques are being used. Such systems are generally rated in "bits per second" bps. It is worth noting that manufacturers will claim the highest figure they can for this parameter, so that the figure will include bits which are part of the signalling protocol rather than the user's data, and may even incorporate an assumption about the compressibility of the data. It is rarely (if ever) valid to divide bps by 8 to arrive at bytes of data transmitted/expected per second.
