|Format||Member Price||Non-Member Price|
Four channel wavelength division multiplexing (WDM) in the range of 800-900 nm is Quante's solution to the demands of the German post office BIGFON field trial in Berlin. After a short description of the technical requirements of BIGFON the features of Quante's WDM system as used in Berlin will be outlined. The advantages of a 4 x 140 Mbit/s WDM transmission system with full duplex capability are compared with other possible methods. Possibilities for the future will be outlined in the end and their availability as well as their commercial aspects will be discussed.
