Performance Penalties Due To Cascaded Erbium-Doped Fiber Amplifier Power Transients In Wavelength Routed Optical Networking

We have investigated the fast power transient effect of the cascaded erbium-doped fiber amplifiers (EDFA) in wavelength wavelength routed optical networks. The BER degradation of surviving channel was measured at the different adding/dropping frequencies of the disturbed channels. The result show that, for low channel-adding/dropping frequency closed to EDFA transient rate, the transmission performances of the surviving channels are impaired severely.
