Abstract
A 16-channel optical FDM distribution/transmission experiment at around 1534nm wavelength is demonstrated utilising an Er3+-loped fibre amplifier. 16 intensity-modulated optical signals at 622 Mbit/s were amplified simultaneously at a gain of 15.2–18.5 dB. One of the amplified signals is selected using the waveguide frequency selection switch and directly detected with a receiver sensitivity of −38 dBm (Pa=10−9).Keywords
