Abstract:
|
Orthogonal Time Division Multiplexing (OTDM) and advanced modulation formats
represents the future in development of high speeds communications. In this text the
feasibility of OTDM systems combining multilevel modulation is studied. The report
is focused in Differential Quadrature Shift Keying (DQPSK) modulation.
Computer simulations study the performance of an OTDM systems using DQPSK
modulation at 1.28 Tb/s and a 640Gb/s OTDM system combined with DPSK
modulation. Two solutions for channel demultiplexing are shown: Nonlinear Optical
Mirror (NOLM) and Four Wave Mixing (FWM). These techniques need an optical
control signal. Optimums values for set the signals and for the bandwidth of the filter
are evaluated. Furthermore numerical simulations are performed to evaluate the
transmission performances of a 1.28Tb/s OTDM-DQPSK system and a transmission
through 561.6km is demonstrated. |
