Bit-rate flexible high-speed OTDM add/drop multiplexing

In this paper, we have performed numerical investigations on the ADM performance from an aggregate bit stream of 160Gbit/s to 10Gbit/s and 40Gbit/s data rates. A validated SOA model based on was used in our investigations. The input pulses are sech₂ shaped with a pulse width of 1.5ps. The delay between control pulses was set to ΔT=6ps and the average data power was assumed to be -15dBm while the control power was varied. In the present work we assume that the data signal does not saturate the amplifier, i.e., the gain and phase dynamics are determined only by the control signal.
