What are the three modes? |
** Singlemode fiber ** Step-index multimode fiber ** Graded index multimode fiber |
|
|
Describe Singlemode fiber (1 of 3) |
Carries an optical signal through a small core, allowing only a single beam of light to pass |
|
|
Describe Singlemode fiber (2 of 3) |
A laser, operating in the infrared portion of the spectrum, is modulated in intensity to transmit the signal through the fiber |
|
|
Describe Singlemode fiber (3 of 3) |
Provides bandwidth of up to 30 MHz |
|
|
Describe Step-index multimode fiber (1 of 3) |
Contains a core surrounded by cladding |
|
|
Describe Step-index multimode fiber (2 of 3) |
When light from the core enters the cladding, a "step down" occurs due to the difference in refractive indices |
|
|
Describe Step-index multimode fiber (3 of 3) |
Uses total internal reflection to trap light |
|
|
Describe Graded index multimode fiber (1 of 2) |
Possesses variations in the core glass |
|
|
Describe Graded index multimode fiber (2 of 2) |
Provides up to 2 GHz of bandwidth |
