Coupling efficiency can be improved by the use of a lens between the source and the fiber. The lens matches the output angle of the source to the acceptance angle of the fiber. From a transmission point of view, the Atech Lucent WDM Modem most important fiber param- eters are bandwidth and attenuation. The fundamental reason we are using fiber instead of copper cable is the increased bandwidth. Band- width is the difference between the highest and the lowest frequency[…]
