PRODUCT INFORMATION A Light Emitting Diode is a device which converts electrical energy to light energy. LED’s are preferred light sources for short distance (local area) optical fibre network because they: are inexpensive, robust and have long life (the long life of an LED is primarily due to its being a cold device, i.e. its operating temperature being much lower than that of, say, an incandescent lamp),can be modulated (i.e. switched on and off) at high speeds (this property of an LED is also due to its being a cold device as it does not have to overcome thermal inertia),couple enough output power over a small area to couple to fibers (though the output spectrum is wider than other sources such as laser diodes). LEDs have significant advantages over incandescent and florescent technologies and as such they are expected to transform the global lighting sector. LED lighting has the potential of consuming up to 90% less electricity than incandescent bulbs and also offer signifi...
