How do optical cables transmit data?
LEDs or lasers
What are optical cables made of?
Thin strands of glass or plastic
How does EMI affect optical cabling?
Optical cabling is immune to EMI
What speeds can optical cables provide that others can’t?
terabits or petabits per second
Single-Mode Fiber (SMF) travel path
One beam of light to travel in a straight path
Typical color used for Single-Mode Fiber
Yellow sheath
Multi-Mode Fiber (MMF) travel path
Multiple beams of light bounce within the cable
Single-Mode Fiber ideal path of distance
Longer distances, more than several kilometers
Multi-Mode Fiber ideal path of distance
Shorter distances, up to 2 kilometers
Typical color used for Multi-Mode Fiber
Aqua blue of orange sheaths
Single-Mode Fiber typical locations
Internet service and long-haul telecom lines
Mutli-Mode Fiber typical locations
Patch cables in data centers
Subscriber Connector
Stick and click mechanism; two cables bundled together
Straight Tip Connector
Stick and twist mechanism; separate cables
Lucent Connector
cables attached side-by-side
Mechanical Transfer Register Jack
