Structured Cabling Solutions
Based in Maryland and Washington, D.C.

How can you avoid poor performance and network breakdowns? By ensuring that your voice and data cabling is the right type, age, and condition to meet your needs.

Our Cabling Approach

The quality and reliability of your network begins and ends with your cabling. Think of it this way: you could have the most well-equipped vehicle on the market, but it’s just no good to you if it’s running on flat tires.

To extend the metaphor just a bit, the tires you bought years before will inevitably grow tired, and newer and better options are available that will take your performance to a whole new level. Without them your machine will never reach its full potential.

You may have invested in the ideal technology to keep your facility connected and running optimally, but you’ll never enjoy the complete return on your investment if your cabling is holding you back. Here at Teltek, we can help your mission-critical technology thrive with assessments, installation, and maintenance completed by our BICSI-certified technicians.

    What is voice and data cabling?

    We may live in a wireless world, but cabling is still the lifeblood of your facility’s networks. It’s the direct link between your end device (computer, phone, printer, camera, speaker, etc.) and the technology you rely on.

    This physical cabling is run throughout your facility’s walls and ceilings, linking your voice and data connections to telephone closets and server rooms (which should be kept cool by the way).

    Here’s a quick look at a few of the most common terms/options that you’ll encounter for voice and data cabling.

    CAT 7

    If you need to support increased bandwidths, up to 100 Gbps at a range of 15 meters (slowing down over longer runs), CAT 7 cabling is a high-performance option. Not every facility will need this, but similar to CAT6a the “future proof” capabilities are important to factor in.

    CAT 6

    This is recommended for new cable installations due to ever-increasing technological demands, and works for both voice and data. The basic ingredients are the same as the CAT5 and CAT 5e, but the bandwidth capacity is extended to 250 MHZ, with speeds of 10Gbps.

    CAT 6a

    Take all of the advantages of CAT6 cabling, double the bandwidth capacity to 500 MHZ, and add more (and tighter) twists and insulation to minimize crosstalk (interference). The increase in cost and cable size, compared to CAT6, used to be a deterrent, but both have shrunk over the last several years making CAT6a a serious contender for structured cabling installation. One additional bonus is that CAT6a is stated to be “future proof,” meaning that if you’re looking for a network upgrade that can handle ever-increasing demands over the next 10+ years, this option provides serious growing room.

    CAT 5

    More commonly known as an ethernet or LAN cable, CAT 5 cabling can support faster data speeds than CAT 3, and can also withstand much longer runs between computers or switches thanks to its increased overall performance and more robust capabilities.


    The classic coaxial cable has been around for decades, delivering a tried-and-true reliability for internet delivery and cable TV applications. Thanks to its shielded structure, very little outside interference can inhibit the copper core from doing its job. It is limited, however, especially because of higher demands placed on it by today’s technology, making fiber optic a more suitable option in some cases.

    Fiber Optic

    While coaxial relies on copper wires, fiber-optic cable utilizes ultra-thin glass fibers that use light to transmit data. This is important because it offers the fastest speeds available, and glass is not susceptible to lighting and water: the two main outage-causing factors in copper-based cabling infrastructures.

    CAT 3

    Also known as a station wire, CAT 3 cabling is an unshielded twisted pair cable (UTP) that was a staple in network communications for a long time. It was most commonly used for LAN networks, capable of voice and low-speed data transmission.

    CAT 5e

    The “e” is for enhanced, taking the same CAT 5 cabling but ramping up the throughput speeds. CAT 5e is one of the most commonly-used options today for structured cabling.

    Why do I need to assess or upgrade my voice and data cabling?

    The most common reasons include:

    • You just moved into a new office building and need cabling installed, or existing cabling tested, to get your team and facility up and running.
    • You have an old system in need of upgrading.
    • Cables have been damaged and need replacement.
    • You have a mess: overtime server rooms, network racks, and wiring closets get messy and need to be reorganized with proper patch cables, power distribution, and cable management to promote organization and proper airflow.

    If you have an older facility, or aren’t sure which type of cabling you currently have, we would encourage you to consider a system review. Cables have improved tremendously over the years, offering drastic performance increases.

    Also, your current cabling may technically work, but it could be holding you back.

    As we outlined above, the older workhorses that trace their way through walls and ceilings are showing their age. Making strategic improvements and updates can offer incredible, practical benefits.
