Data is converted into the binary digits and then encoded onto a signal that can be transmitted over a proper media. Few Uses: 1. Satellite communications 2. Internet 3.

Signals being transmitted are directed and confined in a n arrow pathway by using physical links. Features: 1. High Speed 2. Secure 3. Used for comparatively shorter distances Types: 1. Twisted Pair Cable 2. Coaxial Cable 3. Fibre Optics Cable Transmission Me dia Transmission Me dia Twisted Pair Cable It was invented by Alexander Graham Bell. Twisted pair cables have two conductors that are general ly made up of copper and each conductor has insulation. These two conductors are twisted together , thus giving the name twisted pair cables. One of the conductors is used to carry the signal and the other is used as a ground reference only.

It is used with RJ - 11 connector and RJ - 45 connector. Pros and Cons of UTP These cables are cost - effective an d easy to install owing to their co mpact size. They are generally used for short - distance transmission of both voic e and data. It is less costly as compared to oth er types of cables. The connection established usin g UTP is not secure. They are efficient only for a dist ance up to 100 meters and have to be installed in pieces of up to 100 meters. These cables have limited band width. RJ Connectors RJ - RJ - 11 connector Used for Telephone Communication RJ - 45 connector Used for Ethernet Cables Add your title • Add your title 1 • Add your title 2 • Add your title 3 • Add your title 4 Shielded Twisted Pair (STP) These types of cables have extra insulatio n or protective covering over the conduct ors in the form of a copper braid covering This covering provides strength to the ov erall structure of the cable. It also reduce s noise and signal interference in the cabl e. Pros and Cons of STP They are generally used for long - di stance communication and transm ission and are installed undergrou nd. The protective shield prevents ext ernal electromagnetic noise penet ration into the cable. They have a higher bandwidth as c ompared to UTP. These cables are very expensive and require a lot of maintenanc e which increases the cost more These can be installed undergro und only. The length of the segment is si milar to UTP for these cables Add your title here Add your words here,according to your need to draw the text box size.Please read the instructi ons and more work at the end of the manual te mplate.

The core copper conductor is used for the transmission of signals and the insulator is used to provide insulation to the copper cond uctor and the insulator is surrounded by a braided metal conduct or which helps to prevent the interference of electrical signals an d prevent cross talk. This entire setup is again covered with a pro tective plastic layer to provide extra safety to the cable. Coaxial Cable Application Television : Coaxial cable used for television would be 75 Ohm and R G - 6 coaxial cable. Internet : Coaxial cables are also used for carrying internet signals, R G - 6 cables are used for this. CCTV : The coaxial cables are also used in CCTV systems and both RG - 59 AND RG - 6 cables can be used. Video: The coaxial cables are also used in video Transmission the RG - 6 is used for better digital signals and RG - 59 for lossless transmissio n of video signals.

Components of Fibre Optics Core: It is the central tube of very thin size made of optically transparent dielectric medium and carries the light transmitter to receiver and the c ore diameter may vary from about 5 - 100um. Cladding: It is outer optical material surrounding the core having reflecti ng index lower than core and cladding helps to keep the light within the core throughout the phenomena of total internal reflection. Buffer Coating: It is a plastic coating that protects the fiber made of silic on rubber. The typical diameter of the fiber after the coating is 250 - 300 um.
