Current flber-optic pulse replication techniques for generating high-speed opt;cat pulse patterns are studied. The characteristics of different implementation of the fiber-optic pulse replicators based on different techniques are compared according to the different performance requirements of insertion loss, periodicity and power stability of the output pulses in various applications. Through the theoretical analyses of the key parameters of the replicated pulse output from these devices and their limiting factors, the feasibility and methods for further optimization of the output are presented. The optical pulse activecirculating replicator using optical amplifier is suitable for generating a sequence of pulse trains with precise periodicity and high output power.
