Spade Connector
• Spade Connector
• Low Capacity - 6 Channels
• Separate signals - Video and Audio
2
Coaxial Cable
• Characteristics
•High Capacity - 100 + channels
•Carries Video and Audio signal together
•This cable is used to send the WIRO signal to all the
Iroquois classrooms.

Coaxial Cable - Connectors
F -Connector
• Standard in Cable Industry
F -Coupler
• Connects two coaxial plug ends
BNC
• Used to adapt composite and coaxial
• Locking mechanism
4
RCA Cable
• Wire carries only one signal
• Video, Audio Left or Audio Right
• Higher quality picture and audio than coaxial
cables

S -Video Information
• Separate carriers of video signal
• Luminance (Y) -black & white, brightness
• Chrominance (C) - color
• Separation of video signal provides better picture
resolution than RCA and Coaxial

Fiber Optics Cable
Cladding
Advantage and Disadvantage
•Provides HIGH QUALITY Sound
•Less Susceptible to interference
•Less Durable than wire/cable
Connector:
Core
Buffer coating
• Mini BNC
Characteristics:
Core - Thin glass center of the fiber where the light travels
Cladding - Outer optical material surrounding the core that reflects the
light back into the core
Buffer coating - Plastic coating that protects the fiber from damage and

moisture
Fastening Method (Crimping)
 Used to attach F-connectors to coaxial cables
17
Fastening Method (Soldering)
 Soldering a method of joining metals using fusible
alloys, usually tin and lead, having melting points
under 700 degrees Fahrenheit
 Used to attach: RCA, S-Video, XLR connectors
Soldering Iron
Fusible alloy
Soldering Iron
18
Fastening Method (Fusing)
 Used to bond two pieces of Fiber Optic cable
 It melts the end of two separate pieces of
glass tubing to form one continuous piece of
glass tubing.

Attenuation
Attenuation-Loss/weakening of a signal
•Heat/Climate
•Connection lost
•Length/distance traveled
20
Meter Usage
• Continuity:1 = 100% Resistance Bad
• Continuity: 0 = No Resistance Good
Resistance is measured in Ohms (Ώ)
