Network cable
The document discusses different types of cables used for network transmission including coaxial cables, twisted pair cables, and fiber optic cables. It describes the key characteristics of common coaxial cable types like RG-58, RG-8, RG-6, and RG-59. It also covers unshielded twisted pair (UTP) cables, shielded twisted pair (STP) cables, single mode fiber optic cable, and multi-mode fiber optic cable.

- 3. Coaxial cable • Consistof a solid copper core surrounded by an insulator mainly made up of Poly Vinyl Chloride (PVC) or Teflon • Coaxial cables are less prone to interference (both internal and external)
- 4. Types of Coaxialcable • Coaxial cables are mainly divided into four categories Types of Coaxial cables RG58 RG8 RG6 RG59
- 5. RG58 • Maximum segmentlength is 200 meters • Interference protection is better than twisted pair cables • Offers resistance of 50 ohms • BNC-T connector is used to connect this cable • Used in thinnet (10BASE2) network • Mostly used in changing environments • Easy to add/remove devices form the network using RG58 cable • Cheapest form of coaxial cable
- 6. RG8 • Maximum segmentlength is 500 meters • Interference protection is good compared to any copper cable • Offers resistance of 50 ohms • AUI and Vampire Tap connector is used to connect this cable • Used in 10BASE5 network • Expensive than RG58 • Disadvantage is rigidness due to which it is only used as a backbone
- 7. RG6 • Broadband quad-shielded cable that offers an impedance of 75 ohms • Provides lower attenuation characteristics • Useful in cable TV, CCTV and satellite dish antenna • Covers distance up to 1500 feet (450m approx)
- 8. RG59 • Solid conductoris surrounded by a foam polyethylene dielectric • Offers impedance of 75 ohm and used with BNC connector • Useful in security camera, cable TV and home theatre • Covers a distance up to 1000 feet (300m approx) • Has a higher attenuation as compared to other coaxial cables
- 9. Twisted Pair Cables •A pair of cables twisted around each other forms a twisted pair cable. Twisted Pair cables Unshielded Shielded Twisted Pair Twisted pair
- 10. UTP Cables • Pairof unshielded wires wound around each other • Cheapest form of cables available for networking purpose • Highly used in LAN environments • Easy to install • Easily gets affected by EMI and RFI
- 11. UTP Cables • Maximum cable length – 100m • Bandwidth – 100 Mbps • Connector – RJ45 • Bend Radius – 360 degree/feet • Resistance – 50 ohm • Signal Transmission Mode - Baseband
- 12. UTP cable types • CAT1 – telephone cable • CAT2 – 4 Mbps • CAT3 – 10 Mbps, 16 MHz (10 Base T) • CAT4 – 16 Mbps, 20 MHz (Token Ring) • CAT5 – 100 Mbps, 100 MHz (100 Base T) • CAT5e – 1000 Mbps, 100 MHz (22 Gauge) • CAT6 – 1000 Mbps, 250 MHz (24 Gauge) • CAT7 – 600 MHz
- 13. STP Cables • Pair of wires wound around each other is placed inside a protective foil wrap • Better protection from EMI, RFI and crosstalk as compared to UTP • STP is cheaper than fiber optic cable but costlier than UTP
- 14. Types of STPCables • CAT5e – Operates at 350 MHz and carries data up to 1000 Mbps • 150 Ohm Shielded Cable – Operates at 16 MHz
- 15. Fiber Optic Cable •Bandwidth – Carries large amount of data ranging from 100 Mbps to 1 Gbps • Segment Length – Transmits data signals over larger distance (2 – 100 K.M.) • Interference – No electric signals pass through these types of cables thus providing security. Used in areas that are highly susceptible to noise, e.g. near TV towers, radio stations and electric transformer.
- 16. Fiber Optic CableTypes • Fiber optic cables can carry signals in a single direction. • Light signals are turned on and off in order to transmit data Fiber Optic Cable Types Single Mode Multi mode
- 17. Single Mode FiberOptic cable • A type of cable that has only a single strand of glass fiber with a thin diameter. • Fiber optic cables that use lasers are known as single mode cable. • Data can be transmitted at higher speeds and over long distances
- 18. Multi Mode FiberOptic cable • A type of cable that contains a glass fiber with a larger diameter. • It is a 62.5/125 micrometer fiber cable.
- 19. Multi Mode FiberOptic cable • Multiple modes of light signals can be propagated through it • Transmits data over short distances • Use LEDs as source of light • Used to transmit two or more signals using a single fiber • Speed is less as compared to single mode fiber optic cable • Widely used now a days
