The Difference between Twisted Pair, Coaxial and Fiber Optic Cables
Most of us know the general distinction between ADSL, COAX andFiber internet, but the cabling behind these connections may be more of a mystery. The three most common types of communication cables are Twisted Pair, Coaxial, Fiber Optic.
Understanding the differences between the three will shed light on how data travels through each cable, which ultimately affects your connection and things like speed, latency, security, cost, etc. Here is a general breakdown of the three different types of cable systems and what they are capable of:
Twisted Pair Cables:

Twisted pair cables are quite literally a pair of insulated wires that are twisted together to help reduce noise from outside sources. While this does help some, these cables are still very susceptible to outside noise. Twisted pair cables are the most cost-effective option of the three but that also brings about lower bandwidth and high attenuation. There are two types of twisted pair cables:
Unshielded twisted pair (UTP)
‘Unshielded’ meaning it does not rely on physical shielding to block interference
Most commonly used cable of the two, often utilized for both residential and business use
There are several UTP categories, which increase in bandwidth as you move up the scale, for example:
CAT1 = up to 1Mbps | CAT2 = up to 4 Mbps | CAT5e = up to 1Gbps
Shielded twisted pair (STP)
‘Shielded’ with a foil jacket to cancel any external interference
Commonly used for large-scale enterprises for high-end applications as well as exterior cabling that may be exposed to environmental elements.
Coaxial Cables:
Coaxial cables are high-frequency transmission cables made up of a single solid-copper core. Data is transferred electrically over the inner conductor and has 80X more transmission capacity than twisted pair cables.
This type of cable is commonly used to deliver TV signals (its higher bandwidth makes it more suitable for video applications) and to connect computers in a network. Along with stable transmission of data, coaxial cables also have anti-jamming capabilities and can effectively protect signals from being interfered. The cost is slightly higher than twisted pair but still considered more economical than fiber. There are also two types of coaxial cables:
75 Ohm
Most commonly used to transmit video signals
Often connects video signals between different components like DVDs, VCRs, or receivers commonly known as A/V cables
50 Ohm
Primarily utilized to transmit a data signal in a 2-way communication system
Most commonly used for computer ethernet backbones, AM/FM radio receivers, GPS antenna, police scanners, and cell phone systems
Fiber Optic Cables:
Fiber is the newest form of transmission cable technology. Instead of transferring data over copper wires, these cables contain optical fibers that transmit data via light, rather than pulses of electricity. Each optical fiber is individually coated with plastic layers and contained in a protective tube, making it extremely resistant to external interference. The result is a very reliable and super fast connection that has 26,000X more transmission capacity than twisted-pair cables, but that also comes with a much higher cost. Again, there are two types of fiber cables:
Singlemode
Has a small core and only allows one mode of light to propagate at a time
Because of this, the number of light reflections decrease as they pass through the core
The result is low attenuation and data that is able to travel further and faster
Commonly used in telecom, CATV networks, and Universities.
Multimode
Has a larger core diameter that lets multiple modes of light propagate
The amount of light reflections increase as they travel through the core, which allows more data to pass through
Because of its high dispersion, multimode cables have lower bandwidth, higher attenuation and reduced signal quality further it travels
Most commonly used for communication over short distances such as LAN, security systems, and general fiber networks.

The Details of the cables are given below.
- coaxial cable
- twisted pair
- optical fiber
Explanation:
1. Coaxial cable:
- Coaxial cables are the directed media which care the higher frequency range signal compared to the twisted pair cable. Coaxial cords are also called coax cables.
- A coaxial cable is made up of several short cables within a protective shell. The mask shields the cable from both physical and electronic perturbations.
2.Twisted pair:
- It is used for Ethernet services as well.
- These wires helps for electromagnetic wires basically sued for telephones.
3.Optical fiber:
- Optical fiber is the infrastructure concerned with the transfer of data using light signals that pass through a long cable that is normally composed of plastic or glass.
- For transmission in optical fiber communication, metal wires are preferred as signals pass with less disruption. Electromagnetic interference therefore does not affect the optical fibers.
