Optical Fibers in Communication
... Two types of light source are used with fibers, LEDs and Laser Diodes. LEDs can operate in the near infrared (the main wavelengths used in fibers are 1300nm and 1550nm, along with 850nm for some applications); they can emit light at 850nm and 1300nm. They also have the advantages of long lifetimes a ...
