Principle and application of optical fiber communication
9/20/15 | Technical Article | FiberOnSale.comPrinciple of optical fiber communication is first necessary to transfer in the sender information (such as voice) into electrical signals, and then modulated onto the laser beam emitted from the laser, so that the intensity of light with the electric signal amplitude (frequency) changes, and sent through an optical fiber; at the receiving end, the detector receives the optical signal converts it into an electric signal, after demodulation to restore the original information.
DWDM role of technology
5/21/15 | Technical ArticleDWDM is an optical fiber communication transmission technology, it is the use of an optical fiber can simultaneously transmit a plurality of different wavelengths of light characteristic wavelength range into the fiber may be applied to a number of bands, each band used a separate channel to transmit a predetermined wavelength of the optical signal technology.
The rapid growth of optical fiber communication optical module business fierce market competition
