One way – Fiber to the Home


How fast is fiber optics

Copper wire (twisted pair) up to ~ 100 Mb/sec (short distances)

1,500 phone calls

2 TV channels

2 Bibles/sec

Coaxial cable (also copper) Up to ~1 Gb/sec (short distances)

15,000 phone calls

20 TV channels (> 200 with “data compression”)

20 bibles/second

Optical Fiber up to 50 Tb/s (50,000 Gb/s) (long distances)

0.78 billion phone calls

1 million TV channels

1 million Bibles/second

Introduction to optical fibers
Introduction to Optical Fibers. distances)

  • Fibers of glass

  • Usually 120 micrometers in diameter

  • Used to carry signals in the form of light over long distances

  • No repeaters needed.


Introduction cont
Introduction (Cont…) distances)

  • Core – thin glass center of the fiber where light travels.

  • Cladding – outer optical material surrounding the core

  • Buffer Coating – plastic

    coating that protects

    the fiber.


Type of fibers
Type of Fibers distances)

Optical fibers come in two types:

  • Single-mode fibers – used to transmit one signal per fiber (used in telephone and cable TV). They have small cores(9 microns in diameter) and transmit infra-red light from laser.

  • Multi-mode fibers – used to transmit many signals per fiber (used in computer networks). They have larger cores(62.5 microns in diameter) and transmit infra-red light from LED.



FTTX distances)

  • Refers to several different optical fiber architectures

  • Most Common terms:

    • Fiber to the node / neighborhood (FTTN)

    • Fiber to the building (FTTB)

    • Fiber to the home (FTTH)
