Basic Cable Construction Insulation Drain Jacket Rip Cord Shield Conductor
Conductor • Solid • Bare Copper • Tinned Copper • Reduces Corrosion • Soldering • Stranded • More Flexible • Increase surface/frequency response • Bare copper is less expensive • Tinned copper • Need when soldering connector to the wire or in a corrosive environment (where temps over 100 degrees C or near salt water) • See this in Belden’s line, can convert if not installing in the above environment Solid Bare Copper Solid Tinned Copper Stranded Bare Copper Stranded Tinned Copper
Conductor • Gauge Size can have an impact on performance • Factors: • Length of Run • System Manufacturer’s requirements • Remember: the larger the number, the smaller the gauge • 24 AWG is the smallest gauge we carry
Straight Lay or Cabled • Straight Lay • Cost effective in installations where interference is not a concern. • Cabled • Assists in reducing EMI and RFI interference • EMI - Electro Magnetic Interference • May be caused by electric motors, ballast, etc • RFI - Radio Frequency Interference
Shielding • The addition of a shield offers increased resistance to EMI and RFI • Shield Types • Aluminum Backed Mylar Tape • All Aluminum/Mylar shielded cables include a drain wire • Bare Copper Braid and Tinned Copper Braid • We currently only carry this in coax
Wire Types • Shielded vs. Unshielded • There are a variety of overall shielded (OAS) products • Offers increased resistance to EMI & RFI interference and added protection against cross talk • Stranded vs. Solid • Though cost is slightly higher, stranded cables afford greater flexibility and ease of installation • Multi-Pair Cables • Variety of cables available typically per preference of residential or commercial installer Helpful Hint: Look at similarities in Part #’s #1204 = 22/4 STR Non-Plenum OAS #2204 = 22/4 STR Riser OAS #3204 = 22/4 STR Plenum OAS
Wire Types • Plenum (CMP, FPLP) • Cables used in air space (plenum ducts / ceilings; is the space that can facilitate air circulation for heating and air conditioning systems) must have fire-resistant, low smoke producing characteristics • Plenum constructions are very similar to non-plenum but more expensive • Much of plenum cable products used in commercial applications • Riser (CMR, FPLR) • Suitable for use in a vertical run (floor to floor) • Fire resistant characteristics preventing fire from traveling from floor to floor • Non-Plenum (CM, FPL) • General Purpose • Listing excludes installation in risers & plenums • Bulk of what we manufacture & sell Helpful Hint: Look at similarities in Part #’s #1104 = 22/4 STR Non-Plenum #2104 = 22/4 STR Riser #3104 = 22/4 STR Plenum

Plenum Cable • More commonly used in commercial installations • Low flame spread • Low smoke producing characteristics.
What makes a good speaker wire? • Stranded conductors • More strands = more flexible • Promotes “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 travels • Oxygen Free • Oxygen is a natural impurity in copper • Copper can be annealed to remove that oxygen • Just like these pennies, speaker wire can oxidize • Oxidized strands will impede the signal • Oxygen-Free speaker wire will not oxidize over time
What makes good speaker wire • Zip Construction vs. Cabled Construction • Easy to strip • Home Theater Sound, Home Theater Sound Plus & Audacious • Genelene Insulated Conductor + Semi-Loose Tubed PVC Jacket • Jacket won’t stick to the insulation like PVC + PVC constructions • Crystal Series • Genelene Insulated Conductor + Pressure Extruded TPE Jacket • Most flexible, easy to use speaker wire • Easy to label • Speaker, Room & Zone Code on Legend Subject To Interference Reduces Interference L= Left LR= Left Rear C= Center RR= Right Rear R= Right Speaker Code Room Code Zone Code
Speaker Wire…Power Loss • Analog Transmission of a signal degrades as the length of the run increases. • Your speaker requires a maximum amount of loss. • Use this chart to decide what gauge speaker wire you need For 0.5 dB loss (or 11%) 0’ 60’ 100’ 120’ 190’ 16 AWG 4 Ω 4 Ω = 4 ΩSpeaker 8 Ω 8 Ω = 8 ΩSpeaker 14 AWG 4 Ω 8 Ω

Attenuation Comparison (Signal loss over distance) The lower the dB/100ft at 1000MHz and 3000MHz the better the cable
Coax • RG6 CATV • Do not pull with more than 35lbs • Max. bend radius is 3 inches • RG59 CCTV • Max. pull strength of 25lbs • Max bend radius of approx. 2.5 inches • See handout for coax run lengths
Applications for Category Cable • Cat 3 • Voice only networks • 10/100 Mbs • No future-proofing • Cat 5e • Voice and Data networks • Gigabit Ethernet • Cat 6 • Data Networks • 10 Gigabit Ethernet • Commonly used in hospitals, schools, large offices, etc.
Category Rating System (What you hear about) *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.
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 Talk • How much adjacent pairs “accidentally share information” • Reflection • How much interference there is based on signal accidentally reflecting (changing direction) due to cable imperfections • ACR • Attenuation to Crosstalk Ratio is the amount of signal relative to the amount of noise. (The higher the better)
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.
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)
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 information • With Cat 5e and beyond: • All 4 pairs send and receive information • Imagine both sides of the highway • Since each pair is transmitting and receiving a signal on Cat 5e and Cat 6, interference due to reflection becomes much more disruptive.
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 up • More errors will occur • Network will slow down • Cable 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 cords • Maximum Demarcation to furthest outlet can’t exceed 150 meters (492 feet) • Cable improperly installed • Cable daisy chained • Cable pulled with more than 25 lbs. of pulling tension. • Pairs untwisted more than ½” when terminating • Cable bent beyond 1” bend radius
