Abstract:
Modern communication networks uses optical
fibre extensively. The transport networks are upgrading its
capacity continuously to provide the bandwidth requirement of
the customer requirements. To provide such an increase in
bandwidth, the transmission networks are moving from
Amplitude Shift Keying modulation methods to Phase Shift
Keying methods. In phase shift keying systems, data reception
and regeneration required phase synchronization. This
requires original optical carrier phase information. In this
paper, we report a model for optical carrier recovery for
optical synchronization of a Binary Phase Shift Keying input
by exploiting Four Wave Mixing in Highly Non-Linear Fibers.
The noise influence from the signal laser for the recovered
carrier was analyzed.
