Optical fiber Losses
We have already discussed Optical fiber, Power meter and OTDR in our previous videos. Today we will focus on fiber losses only. Fiber Optic Comm Fiber optic cable is lighter, smaller and flexible than copper cable. It can transmit optical signal with faster speed over longer distance. Many factors can influence the performance of… -
