16 What makes a good speaker wire? Stranded conductorsMore strands = more flexiblePromotes “Skin Effect”The signal travels on the outside of the conductor, like the skin is on the outside of your finger.The more strands, the more “outsides” or surface area for the signal to travel across…so the better it travelsOxygen FreeOxygen is a natural impurity in copperCopper can be annealed to remove that oxygenJust like these pennies, speaker wire can oxidizeOxidized strands will impede the signalOxygen-Free speaker wire will not oxidize over time

26 Category Rating System (What you hear about) (ENHANCED)Cat 6StandardFrequency(MHz)1620100350*250Genesis Frequency3240200350500Network Throughput10 Mbps100 Mbps1 Gbps1Gbps10 Gbps*Cat5 350 (aka ENHANCED or Cat5E) is not regulated by the TIA Category Rating system, therefore users should not assume Cat5e compliance on all electrical values. Consult factory for complete test results.
27 What’s really important? Although Frequency is the electrical characteristic most often discussed with category cable it is not the best indicator of network performance.When a manufacturer says their cable is tested at a certain level, ask for the test results.Most ‘low end’ manufactures that claim a high frequency rating do not meet the TIA specifications for all electrical values.Better indicators of network performance are:Near End Cross TalkHow much adjacent pairs “accidentally share information”ReflectionHow much interference there is based on signal accidentally reflecting (changing direction) due to cable imperfectionsACRAttenuation to Crosstalk Ratio is the amount of signal relative to the amount of noise. (The higher the better)
28 What’s really important? (cont.) Near End Cross Talk – how does it go bad?Category cable has four pairs that are each twisted in a slightly different way. Those four pairs are also cabled together in a specific ways too.This twisting scheme is like the lane lines on a highway.The Category Rating System specifies a certain type of twisting scheme that allows the signals to travel optimally.The signal travels with peaks and valleys that, when on a quality category cable, work well together.If there are any imperfections in the way that cable is designed or manufactured those twists can fall out of place, and the peaks and valleys begin to interfere with each other.Improper installation is also a major cause of those twists falling out of place.Imagine a highway where the lane lines were to run together, cars would be cutting each other off, and the traffic would slow down.
29 When am I going to notice a problem? Before Cat 5e the best networks were transmitting 10 or 100 Megabytes per second.They are often referred to as 10/100 networks and are still the most popular today among small networks.Cat 5e was designed for Gigabit Ethernet (1,000,000 bytes of information per second)Gigabit Ethernet is available on many computers and network devices purchased in the last few years.Cat 6 was designed for 10 Gigabit Ethernet (10,000,000 bytes of information per second)
30 When am I going to notice a problem? Gigabit and 10 Gigabit Ethernets transmit data in a new way.Before Cat 5e:2 pairs were used for sending information &2 pairs were used for receiving informationWith Cat 5e and beyond:All 4 pairs send and receive informationImagine both sides of the highwaySince each pair is transmitting and receiving a signal on Cat 5e and Cat 6, interference due to reflection becomes much more disruptive.
31 When am I going to notice a problem? Little problems within a network build up until a point at which the network fails.Too many users on a network:More bandwidth is used upMore errors will occurNetwork will slow downCable runs too long within a network:Cable runs are not to exceed 100 meters (328 feet)90 meters (295 feet) from distribution device to outlet.Maximum 10 meters (33 feet) for Equipment Cords and Patch cordsMaximum Demarcation to furthest outlet can’t exceed 150 meters (492 feet)Cable improperly installedCable daisy chainedCable pulled with more than 25 lbs. of pulling tension.Pairs untwisted more than ½” when terminatingCable bent beyond 1” bend radius
