Transmission Performance Analysis of Fiber Optical Parametric Amplifiers for WDM System
Figure 2
The schematic configuration of long-haul WDM transmission system employing cascaded FOPAs. Eight channels are multiplexed (total power is −3 dBm before Mux) to transmit through spans of conventional fiber. Loss is compensated by FOPAs. A preamplifier is applied before the demultiplexer.
