Twisted Pair How does it work Shielding UTP,STP,SSTP Introduction Coaxial cables Twisted pair Ethernet HDMI Optical fibre Examples Conclusions How does it work Shielding UTP,STP,SSTP Foil S/FPT or stranded Most common 100ohm 2013-05-19 Wired communication cables 6

Twisted Pair (Ethernet RJ45) Categories Cat1,Cat2,Cat3,Cat4,Cat5,Cat5e,Cat6,C at7 Most common Cat5,Cat5e Advantages: Only one standard connector Have bin a standard for a long time Fast and reliable (100 Mb/s cat 5 and 1 Gb/s Cat6) Power over Ethernet Quite cheap (13kr/meter for Cat6 with SSTP) Disadvantages Need special press equipment Need one cable to each device, from the router Introduction Coaxial cables Twisted pair Ethernet HDMI Optical fibre Examples Conclusions 2013-05-19 Wired communication cables 7

Twisted Pair (HDMI) 2013-05-19 Wired communication cables 8 Different standards: The connectors The new standard 1.0,1.1,1.2,1.2a,1.3,1.3a,1.4 New classification Advantages: Standard for new products With Ethernet (100 Mbps 1.4) Both for audio and video Fast (10,2 Gbps(1.3,1.4)) Disadvantages: Still expensive Extremely hard to connect yourself The devices needs Ethernet compability Introduction Coaxial cables Twisted pair Ethernet HDMI Optical fibre Examples Conclusions 2013-05-19 Wired communication cables 8

Optical-fibre 2013-05-19 Wired communication cables 9 Optical fibre is a cable: Optical signals Transmitter Receivers Advantages: Light-weight Immune to noise Low attenuation Secure The more commercial ones is fast (1.6 Tbit/s) Disadvantages: Are still to expensive (About 27kr each meter) No good standard for the private market A little overkill to have at a house, better for distribution Need some really expensive equipments, receivers and transmitters Introduction Coaxial cables Twisted pair Ethernet HDMI Optical fibre Examples Conclusions 2013-05-19 Wired communication cables 9
