Video Cables

Video can be divided into several applications: Video Cables Video can be divided into several applications: Broadband/CATV DBS Precision Video Component Video

Broadband/CATV Video Cables Copper covered steel conductors Aluminum braid shield(s) Foil shield tape + 60% braid Sweep Test 50 MHz - 1000 MHz, 20db SRL 75 +/- 3 Ohms TDR Impedance

Composite Cables

Composite Cables These are multi-functional multi-component cables for data, audio, video, security and control. Made of combinations of data, coax, and fiber cables. Watch out for cable performance degradation as compared to individual cables.

Data Cables MAJOR Concern Cross Talk and Return Loss Crushing Composite Cables Data Cables MAJOR Concern Cross Talk and Return Loss Crushing (Impedance, Return Loss) Periodicity / Lay Length (Return Loss, Cross Talk) Proximity (Cross Talk) Binder Tightness Attenuation Low Frequency

Explanation of Degradation Cables are designed to meet their respective requirements. Additional twisting or kinking may destroy the designed pair lay ratios and geometry reducing NEXT performance in data cables. Likewise, RL in coaxial cables. Maximum Pull Tension and Minimum Bend Radius must be maintained. Cables placed under high tension or compression may have attenuation and impedance problems.

Explanation of Degradation Improper bundling can cause irreparable damage to the cable Continuously tightly bound assemblies are at an inherent disadvantage for Alien crosstalk Obtain bundled cables only from manufacturers or distributors that have verified their process and/or are using cables specifically designed to be bundled.

Data Cables Coaxial Cables Problems Manifested Slow Network Network not working Limited to short runs Will not support future system upgrades Coaxial Cables Loss of TV Channels Low signal level to Set Top Box

Security Systems Fire Alarm Security and Combination Systems Sensors to Control Panel

Alarm and Security Cables

Security Systems Fire Alarm cables per NEC 760 Security and Combination Systems Two or Four Conductor 16AWG or 18AWG Stranded 22AWG Solid typical for single dwelling Cat 3, 5e, or 6 where acceptable Sensors to Control Panel Two Conductors (Passive Sensors) Four Conductors (Active Sensors)

Security Systems Security Systems Keypads and User Interface Four Conductors Wire AWG based on 5% voltage drop Voice circuits require Cat 3 minimum Video NEC 820 or 725 Series 6 or Series 11

Alarm and Security Cables Multiconductor Cables Typically bare copper conductors and PVC insulation. Polyolefin insulation on higher grade cables. Unshielded or foil shielded. PVC jacket.

Composite Cables Speaker Wire Audio Cables Parallel (Siamese) Round One Cat5e + Conductors Speaker Wire Bare Copper Oxygen Free or ETP PVC or Polyolefin Insulation

Agency and Regulatory Issues

National Electric Code, NEC NFPA 70 - 2002 The code is purely advisory, but is offered for regulatory purposes in the interest of life and property protection. It is the de facto standard used by all municipalities and inspectors. It is usually the MINIMUM requirement, and is often superceded by more stringent local codes.

National Electric Code, NEC Most Cables fall into one of the following articles of the NEC code. 800 Communication Circuits 725 Class 1, Class 2, and Class 3 Remote Control, Signaling, and Power-Limited Circuits 760 Fire Alarm Systems 820 Community Antenna Television and Radio Distribution Systems

National Electric Code, NEC Within each article, there are typically four fire resistance levels. Residential General Purpose Riser Plenum

National Electric Code, NEC The first level is Residential. Residential cable is limited use and shall be listed as being suitable for use in dwellings and for use in raceway. CMX, CL3X, CL2X; CATVX

National Electric Code, NEC The second level is General Purpose. General Purpose cable shall be listed as being suitable for use with the exception of risers and plenums. MPG, CMG = FT4 Canada MPG, CMG, CM, (PLTC), CL3, FPL, CL2; CATV

National Electric Code, NEC Riser is the next level. Riser cable shall be listed as being suitable for use in a vertical run in a shaft or from floor to floor. MPR, CMR, CL3R, FPLR, CL2R; CATVR

National Electric Code, NEC Plenum is the HIGHEST fire resistant cable and can be used/substituted in all four levels. Plenum cable shall be listed as being suitable for use in ducts, plenums, and other spaces used for environmental air. MPP, CMP, CL3P, FPLP, CL2P; CATVP
