Signal impairment is experimentally studied by using the extinction ratio (ER),error bit rate (BER) and optical spectrum in a three-cascaded semiconductor optical amplifier (SOA ) setup.The signal with the ER of 13 dB and BER of < 10^(-9) is achieved after the signal passing through the cascaded SOAs.With the results obtained from the experiment,we confirm that the three-cascaded SOAs used to compensate for power in the optical transmission can be accepted.This experimental result also offers the possibility of achieving a higher throughput of multiplane architecture by exploiting three switching domains instead of two switching domains in the energy-efficient design of a scalable optical multi-plane interconnection architecture.The space switches in output ports of multi-plane interconnection architecture can be improved to N =32×32 × 32 =32768.
