Benefits of Optical Fiber Communication
l Lower Attenuation than Coaxcial Cablen O.2 dB/KM (1550 nM) or 0.4 dB/KM (1300 nM)
l Very High Bandwidthn Bandwidth is Still no Limitation
l Small Size/Light Weight.n 1/30 to 1/50 Weight&Size of Coaxial Cable
l No Electro-Magnetic Interferencel Speed of Light
n Satellite has 200 ms. delay (not suitable for interactive application butstreams like broadcasting)
l High Security

l Optical Switch
switches optical wavelengths. While the traditionalDCS takes electrical signals in and sends electricalsignals out, the optical switch takes optical signals inand sends optical signals out.
l DWDMworks by combining and transmitting multiple signalssimultaneously at different wavelengths on the samefiber.
