The light transmission and light.The use of fiber-optic equipment is required, receive and send a signal that acts of light. A device that acts as a signal light or the light source is LED or laser diode. The device sends this light acts as a wave of electric waves, light changes. Exposure equipment and change back into electrical signals is a photo diode.Light transmission device or power LED just 45 micro-Watts. For use with fiber optic a 62.5/125, considering this device must see the light wave bar. Normally, the use of light waves, the wavelength is about 25 District-40 nm. Therefore, coordinated requirements of fiber-optic wavelength of light, so it is mentioned that is used in the 850 nm district.The exposure or photodiode receiver is a device that uses light and are sensitive to light intensity. Light waves are sent the letter to signal modules.The transmitter and receiver devices, this light is often made as a success, especially the modules connected to the electrical data signal directly and make it easy to use.
