Communication Cable: What are the Common Types Available in the Market?

Cables are essential for sending and receiving signals. You cannot send data signals on power cables. And you cannot send data signals on power cables. Instead, it would help if you had a communication cable for the data signal transmission.

What are Communication Cables?

Communication cables help in transmitting the data signals on various levels of frequency. Unlike power cables that work on higher voltage or currents, communication cables are ideal for low current and low voltage. Thus, you can use communication cables such as Ethernet cables, data transmission mediums, and networking cables.

Common types of communication cables

You can see communication cables in life as:

CCTV Cables

CCTV cables are some of the most flexible communication cables. You may use them in unusual locations. CCTV cameras are commonly present on ceilings or the exterior of buildings. So workers must run CCTV wires through walls, floors, and ceilings.

In addition to coaxial cables RG59 and RG6, other frequent CCTV cable types include Ethernet cables. However, most CCTV installers use RG59 wires as the norm. But RG6 cables, with their added shielding, may be better if you’re having issues with low video quality or interruptions.

Ethernet Cables

LAN cables, or Ethernet cables, are among the most common cables. Ethernet connections allow families and businesses to access the internet by attaching the cable to the routers, which transmit network signals to other devices. Check to ensure your ethernet cable isn’t loose or misconnected after disconnecting and plugging the router. Customer assistance for internet service providers often walks you through a few stages if you’ve ever had to call them about a network issue.

Ethernet cables are constructed in a variety of ways. Category cables, such as Cat5e, Cat6, and Cat6a, are some of the most prevalent. As you can see, the higher the number (Cat6 vs. Cat5e) is, the more bandwidth it provides. As a result, each of these cables can be constructed differently. Twisted wires, for example, are the norm in the copper wiring industry. After that, you may choose between a shielded and an unshielded cable, depending on your needs.

Telephone Cables

Even though landlines are no longer widespread in homes, companies and office buildings rely on them daily. The RJ12 is the most common type of telephone wire in homes and specific companies, and we tend to think of it as such.

Many phone docks now come with Ethernet and coaxial ports, which are preferable for avoiding network disruptions as they provide a stronger connection. Phone system installers utilize Ethernet and coaxial capabilities in some instances, but others still prefer RJ12. As long as you’re using the correct cable to connect your phones, there is no right or wrong method to do it. 

Computer Network Cables

Computer networking cables come in various forms, including the more traditional coaxial kind. The RJ45 Ethernet cable, thicker than a phone cord but very flexible, is the most prevalent nowadays.

An RJ45 cable may link two computers directly or connect a computer to a network device. Moreover, you can ideally choose RJ45 cables to connect PCs with high-speed Internet access to a modem or router.

Serial Data Cables

In the past, nine or 25-pin connections and reasonably thick cables were standard features of serial communication lines (similar to RJ45). They directly connect PC digital cameras, modems, and other devices.

Even though they aren’t generally thought of as networking cables, they may be used to create a rudimentary “network” by connecting two PCs directly. A computer or a USB power station can power or charge devices using USB communication links, which perform the same functions.

Other Cable Types

Even while certain types of cables are not for a wide range of applications, you can use some cables to connect two devices. A printer or Zip drive can communicate with a computer through a bidirectional parallel connection.

Some ancient computers still use their tape drives to deliver and receive data. Several electronic organizers use particular sorts of communication cords to export or import backup files. Thus, you may send cable TV, telephone audio, and Internet data using coaxial lines.

Terminology Notes of Communication cables

For communication cables, there are several terms that you will hear in the market. These are,

Plenum-rated Cable

Plenum areas have less air circulation, so you need electrical cables recommended for them. Plenum-rated communication cables have fire retardant jacketing material, either a low-smoke PVC or FEP (Fluorinated Ethylene Polymer).

Many types of “Plain” or “house” cabling, including those used as outer jackets and interior insulation, emit hazardous gas when burnt, prompting the development of this technology. They are for use in ventilation ducts to comply with fire regulations. 

Plenum cabling is pricey and comes with a specific Teflon-based outer coat.

Riser-rated Cable

These cables are special for areas where you need to run them under floors. Also, there are no fire or flame restrictions for the riser-rated cables.

CAT5, CAT5E, or CAT6 cable

CAT or Category cables have a twisted wire pair that carries signals and transmits data. A common term for these connections is “Ethernet cable,” which refers to their application in computer networking. It is the fundamental distinction between the three cable categories (CAT 5, 5E, and 6). While CAT5 and CAT5E can carry 1000 megabits per second (Mbps), CAT6 can handle 10 gigabits per second (Gbps). Moreover, an internal divider separates each section in CAT6.

Jelly Filled Cable

Jelly-filled cables have an interesting name to define their inner material. Thus, it is usual for underground wires to be packed with jelly, making them vulnerable to dampness and deterioration. Using jelly-filled cables may lessen or eliminate the risk of moisture damaging your cable instead of digging it up every time it gets wet.

Petroleum jelly fills any gaps surrounding the wires in jelly-filled cables, except those without an insulating layer. Moreover, the cable is protected from moisture by petroleum jelly.

Here, the “Messenger” may have some waterproofing. Still, it has a steel messenger wire running the length of its length to carry the stress associated with an aerial drop from a power line pole. Moreover, it is possible to utilize “flooded” cable in underground areas or direct burying since it contains water-resistant gel.

RG-rating Cable

RG-6 is present in a wide variety, suited for specific use. Commonly, these cables are ideal for interior or outdoor home wiring. The inside is also made of bare or copper-clad steel, depending on the application.
