Application Of Different Types Of Cables

The H07RN- F cable is a physical medium that allows analog and digital data to be transferred. When choosing a line, examine the type of data transfer, the purpose, the benefits, and the drawbacks.

Cables of Various Types

Cables are divided into two categories.

• A twisted pair
• Coaxial
• Optical fiber

Twisted pair cables are made up of two color-coded pairs of insulated copper wires, one used for signal transmission and the other for ground reference. Each wire has a diameter of 0.4 mm to 0.8 mm and is twisted around each other to form pairs wrapped in a plastic sheath.

Depending on the cable type, the number of pairs varies. Cross talk is reduced when a couple of wires has more twists per foot.

The importance of twisting minimizes or eliminates interference generated by radio frequency electromagnetic interference, such as noise or cross talk.

The effect of noise or disturbance on both wires is the same when the wires are twisted. The effective noise is eliminated since the receiver takes the difference between the two wires.

Twisted pair cables are divided into two categories

• Twisted shielded cable (STP).
• Twisted pair cable that is not insulated (UTP).

Twisted Pair cable with a shield (STP)

As the name implies, the shielded twisted pair cable has a conductive covering (usually a metal foil or a mesh) over each pair or the entire line.

Purpose

A twisted pair shield allows for a faster transmission rate.

Advantages

Installation is simple

• When compared to UTP cable, it has a larger capacity.
• It is insulated, allowing for faster data transfer.

Disadvantages

Cables with a larger diameter are more expensive than UTP or coaxial cable.

Applications

• In industrial applications, it's used as an instrumentation cable.
• Used in extreme cold and heat conditions.
• Research applications.

Twisted Pair cable with no shielding (UTP)

Additional shielding, such as mesh or aluminum foil, is not employed in unshielded twisted pair cable, which adds bulk.

Unshielded twisted pair cable comes in a variety of types, each with different bandwidth.

1st category:

Is the term for a telephone line with a poor data rate.

2nd category:

It has a maximum data rate of 4 Mbps.

3rd category:

It has a maximum data rate of 16 Mbps.

4th category:

It has a data rate of up to 20 Mbps.

5th category:

It can handle speeds of up to 200 Mbps.

Purpose

Voice, low-speed, and high-speed data and audio support systems all use untwisted pair wire.

Advantages. 

It is less expensive than a coaxial or optical fiber cable.

For short to medium distances, it's used in computer networking, such as Ethernet.

Disadvantages

The signal attenuation, this cable can only be used for limited distances.

Cable Coaxial

Coaxial cables are also known as coax cables (short form). A multi-layer cable is known as a coaxial cable.

The radio frequency signal is carried via an inner conductor known as the core in coaxial cables. A single solid conductor or multiple strands of twisted cable can be used as the core wire. It has a dielectric insulator surrounding it.

The inner conductor is separated from the outside copper braided mesh by a dielectric insulator. Copper mesh is used to cover the dielectric insulator (foil or braided conductor).

Polyethylene foam or PTFE can be used as a dielectric insulator to reduce ohmic losses caused by contact with the conductors. The cable's outer jacket protects it from environmental and mechanical harm. PVC is a popular option.

The coaxial word refers to the fact that the cable's inner conductor and the braided wire mesh conductor share the same central axis. The impedance of coaxial cables is measured in ohms. Fifty ohms, 75 ohms, and 95 ohms are common impedances.

Coaxial cable connectors come in a variety of shapes and sizes.

The first four are the most common. Types include BNC, SMA, N, and F. The type of signal transmission determines how coaxial cables are classified. Baseband and Broadband cable are the two options.

Cable for baseband. 

It's a digital transmission wire with a resistance of 50 ohms. For optimum performance, it should be used over short distances.

Broadband access through cable. 

It's a 75 ohms resistance cable that's used to transmit analog data. It can be used for up to 100 kilometers.

There are two types of Coaxial cables based on Radio Gauge (RG) standards:

Thicknet and Thinnet. 

Thicknet: Thick Ethernet or 10Base5 systems are RG 8, RG 9, and RG 11 coaxial H07RN- F cable. The number 10 denotes a speed of 10 megabits per second, and the number 5 represents a distance of 500 meters between nodes or repeaters, where Base indicates "Baseband transmission" as the transmission type.

Thicknet cables are made of thicker coaxial cable than Thinnet.

RG 58 Thinnet In 10Base2 systems, a coaxial cable is used. The number 10 denotes a speed of 10 megabits per second, and the number 2 represents a distance of 200 meters between nodes or repeaters.

Fiber Optic Cable

It's also known as fiber optic cable, and it's made up of strands of one or more fibers inside a casing that looks like an electrical cable.

There are three pieces to an optical fiber.

Core

The core is the innermost layer, with a refractive index of n1. In this section, light is steered. The refractive index of the center will be higher than that of the cladding.

Cladding

It has a refractive index of n2 and surrounds the center. Who has a lower refractive index than the core? The goal of cladding is to keep light reflections in the middle rather than reflecting them.

Casing

This is an outer covering that protects the H07RN- F cable from wear and tear. Optical fibers are divided into two categories: glass and plastic. For brief communication, plastic fiber is utilized. In the glass, an optical fiber transmits data at the speed of light.

Optical fiber cable transmits data using light pulses rather than electrical pulses. The dangers of infrared red light, which is employed in telecommunications, are invisible to the naked eye.

Single-mode and multimode optical fiber cables are available.

Single-mode operation

The amount of light reflections in the core of a single-mode fiber optic is lower, resulting in low attenuation and allowing data to go further and quicker. Single-mode communication has the lowest communication losses.

Multimode

The core diameter of multimode connections is bigger. Numerous wavelengths of light can be sent in multiple directions at the same time

Multimode connections are used at shorter distances because signal attenuation is higher, and the data transfer rate is slower due to the increased number of reflections in the core.

Conclusion

Cables of various sorts are utilized in a variety of applications. Not all wires serve the same purpose. The function of a H07RN- F cable is determined by its type. The electrical cables are comprised of aluminium or copper wires protected by a synthetic polymer insulating coating.
