What type of shielded UTP CAT5e cable should I use?

Leave a comment

Shielded UTP CAT5e cable is generally referred to as STP UTP CAT5e or Shielded Twisted Pair UTP CAT5e. This term, however, is used to refer to many different styles of shielding. The most common type of shielding uses what is called a screen.

This screen is a metal covering that goes around the entire set of 8 wires found in UTP CAT5e cable. This can be done by a single solid foil wrap around the wires, braided strands of cable wrapped around all the wires, or a combination of the two. This type of cabling is very effective at blocking any EMI that could cause problems in most installations.

If you want to ensure the proper operation of your network, we would recommend using STP cable like this for all in wall and other critical runs of cable. This way you can rest easy knowing you’re getting the most speed that you can out of your network.

What Matters Most in Speaker Cables?

Leave a comment

Lately we’ve been getting hit with the common question “what speaker wire gauge should I use” or “what matters most in high performance speaker cables”? Is there a difference between 12AWG and 18AWG wire? The short answer is Yes. The higher the gauge, the more resistance. In this case, it’s usually best to follow the advice of the Borg “resistance is futile”. Audiophiles should always wish to minimize speaker cable resistance. Read on to learn why.

More often than not, we’ve seen Audiophiles choose a higher gauge esoteric wire over a lower gauge generic zip cord cable simply because they were sold some marketing nonsense from the exotic cable vendor that their wire will yield higher dynamics and better Mojo from your system than standard generic cable. Check out some of the “midpriced” speaker cables from the likes of Audioquest and Nordost as example and you will see they are anywhere from 16-18AWG. This is much higher resistance than cheap 12AWG zip cord cables you can buy at a local hardware store.

Anytime you are driving power into a low impedance load such as a loudspeaker, the dominant metric of concern is DC resistance (measure of restriction of conductivity in a circuit). Certainly there are secondary concerns which are also important such as inductance, and capacitance. But, as we’ve proven in our various cable articles and reviews, if you cannot first select a cable with low enough DC resistance, the losses will be so great between the amplifier and loudspeaker that all other cable parameters will become a wash. This article will focus solely on cable resistance and will serve as a guide for choosing the right wire gauge (AWG) for your installation to ensure you realize the maximum potential of your setup.

Ultra-HD Combo Cable

Leave a comment

This is a video/audio and camera control combo cable that meets and surpasses the requirements for 4K and 8K Ultra-HD transmission applications.

It developed this new cable for applications where both a stable UHD signal transmission and compact size are important. The new UHD-SDI hybrid cable joins 3 x UHD video (BNC), 2 x digital audio (3-pin XLR) and a camera power supply line (e.g. 4-pin XLR) in one compact cable, and so complements already existing Sommer fiber-optic combo cables.

The 3-in-1 combo cable is flexible, easy to reel and, because of its low damping values, highly recommended for long-distance transmissions. Customers can purchase the new cable in bulk, or premade and ready for connection.

Data Cable Types

Leave a comment

Data cables are used to transmit information between systems such as servers, personal computers and other hardware. There are three main types of data cables used to transmit data: twisted pair, coax and fiber optic cables. These three types of cables are used in different environments. These data cables have different characteristics that make them identifiable.

Twisted Pair

Twisted pair cables are used in telephony and computer networking. Most cable networks are wired using shielded twisted pair, which is a type of data cable that has a covering to eliminate the amount of signal degradation from other sources. Twisted pair gets its name from the twists in the wires that span throughout the cabling. The twists in the cables also help protect the data communications from signal degradation. Twisted pair cabling have a limit to how far they can stretch before the signal becomes corrupted. The average length for a twisted pair wire before signal degradation is 300 feet.

Coax

Coaxial (coax) cable is used in older computer networks. Coax cable was replaced by shielded twisted pair as a standard for computer networking. Coax is still used for cable networks to provide television communication data. Coax cable is a large, round cable with an inner core wire that transmits the data. Surrounding the core is an insulator and shield to protect the data communication signal. Surrounding these parts is the casing. Coax cabling requires a special connector called a BNC connector. Network cards for computers are purchased with these connectors to data cable this type of network.

Fiber Optic

Fiber optic cable is the preferred option for fast data connections. Fiber is used by cable and telephony companies to provide fast connections to the Internet. Fiber optics uses light and glass as the mechanics for data communications. Fiber optic cable is very fragile due to the glass parts of the cable. Fiber optic cable is light weight, and it does not have the signal degradation problems that the other two data cables suffer. However, fiber optic networking is more expensive and requires special network cards and hardware to transmit the signal.

What is CATV cable used for?

Leave a comment

What does CATV stand for? “Community antenna television” now often known as “Community access television” We always like to use caution with CATV vs CCTV cables because they are in many ways different.

CATV cables are constructed using Copper Covered Steel “CCS” mainly for strength when consumers push and pull the coax out of TV’s or monitors, next CATV cable use a bonded foil shield and a aluminum braid as to prevent RF leakage which results in fines from the FCC.

Also CATV cable transmit from low to hi frequencies 5Mhz to 3Ghz as compare to CCTV in low current data signals.

What is coaxial cable and how is it used?

Leave a comment

Coaxial cable is commonly used by cable operators, telephone companies, and internet providers around the world to convey data, video, and voice communications to customers. It has also been used extensively within homes.

It has been around for a long time as a technology (since the early 20th century) and has many singular advantages for reliable, accurate transmission.

It also has limitations that will cause it to be replaced in some cases by fiber optic cable, category cable or, sometimes, by wireless signals.

The key to the coaxial cable’s success has been its shielded design, which allows the cable’s copper core to transmit data quickly, without succumbing to interference or damage from environment factors.

What is coaxial cable?

Coaxial cable is a type of cable that has an inner conductor surrounded by an insulating layer, surrounded by a conductive shielding. Many also have an insulating outer jacket The diagram below illustrates the construction of a typical cable. Electrical signal flows through the center conductor.
