Fiber Media

Question 1

What is Single Mode Fiber (SMF)?

Answer 1

Used for longer distances and has smaller core size which allows for only a single mode of travel for the light signal.

Question 2

What is Multimode Fiber (MMF)?

Answer 2

Used for shorter distances and has larger core size which allows for multiple modes of travel for the light signal.

Question 3

What is Wavelength Division Multiplexing (WDM)?

Answer 3

Combines multiple signals into one signal and sends over a single fiber optic strand.

Question 4

How many wavelength channels does Coarse WDM have?

Answer 4

18 channels.

Question 5

What is the channel distance of Coarse WDM?

Answer 5

20nm.

Question 6

What is the speed of Coarse WDM?

Answer 6

Up to 10 Gbps (Ethernet).

Up to 16 Gbps (Fiber).

Question 7

How many wavelength channels does Dense WDM have?

Answer 7

80 channels.

Question 8

What is the channel distance of Dense WDM?

Answer 8

0.8nm.

Question 9

What is the speed of Dense WDM?

Answer 9

8 Tbps (100 Gbps / channel).
