Optical amplifiers and their applications 90
WebThe development of low-loss optical silica fibres and reliable semiconductor laser sources in the early 1970s have enabled the practical realisation and massive deployment of optical-fibre communications worldwide. However, high bit-rate transmission is severely limited by the fibre residual loss and dispersion [ 1 ]. WebApr 1, 1998 · Figure 3 illustrates a remotely located erbium-doped fiber segment pumped from the receiver terminal via the transmission fiber. In this example, the remote erbium-doped fiber amplifier provides 18 dB of gain at a distance of 123 km from the receiver. Over the last. 60 km before the receiver, the Raman gain from a pump power of 31 dBm …
