Crosstalk in Optically Pre-Amplified Systems
Optical receivers used in multi-wavelength optical networks are often preceded by an optical amplifier for the increase of receiver sensitivity, and thereby extending the transmission reach. However, the destructive effects of interfero-metric crosstalk as a result of leaking signals in a switching node are intensified by the presence of residual amplified spontaneous emission noise in the optical amplifiers. Transmission links using direct and external modulation light sources are investigated and the results show that optical pre-amplification indeed increases the receiver sensitivity but unfortunately at the expense of the network’s tolerance towards in-band crosstalk.
