Claim 8:
9. An optical modulation method performed by an optical modulator including a first transmitter chain and a second transmitter chain, a first optical time division multiplex generator upstream of said first transmitter chain and said second transmitter chain, and a second optical time division multiplex generator and a third optical time division multiplex generator downstream of said first transmitter chain and said second transmitter chain, the method comprising:
generating time interleaved optical pulses by the first optical time division multiplex generator;
transmitting, by the first optical time division multiplex generator, the time interleaved optical pulses to the first transmitter chain and the second transmitter chain;
receiving, at the second optical time division multiplex generator and the third optical time division multiplex generator, the time interleaved optical pulses from the first transmitter chain and the second transmitter chain;
generating, by a finite impulse response filter, correction signals for use by respective tributaries of the optical modulator; and
transmitting an optical signal into an optical fiber based on the time interleaved optical pulses and the correction signals.
