10 Questions
What is the core diameter of multimode fiber?
True
Optical fiber is a metal filament that guides a light wave along its path.
False
Singlemode fiber can only be used to transmit AV signals within a building.
False
A fiber optic transmitter uses a laser diode as a light source.
True
A photodetector is used in a fiber optic receiver to convert the optical AV signal into an electrical signal.
True
What is optical fiber?
Optical fiber is a glass or plastic filament that guides a light wave along its path.
What is multimode fiber?
Multimode fiber is optical fiber that allows light to travel down multiple paths, also referred to as modes. It features a core diameter of 50 to 62.5 microns.
What is singlemode fiber?
Singlemode fiber is optical fiber that allows light to travel down a single path known as the fundamental mode. It features a core diameter of 8 to 9 microns.
How is an AV signal transmitted down a fiber?
A fiber optic transmitter converts the AV signal into an optical signal, using a VCSEL or laser diode as a light source. A glass fiber guides the optical AV signal along its path.
What can singlemode fiber be used for?
Singlemode fiber can be used to transmit AV signals over extreme distances up to many miles or kilometers.
