All-optical timing jitter measurements on 40 Gbit∕s pseudorandom RZ data after long-haul transmission in dispersion-managed soliton system

All-optical measurements of background, amplitude, and timing jitters for high speed pulse trains or PRBS sequences using autocorrelation function

“…The expression for the timing jitter is consistent with the one derived in Ref. [7]. Here we show that it holds true even in the presence of amplitude jitter.…”

“…Another interesting result is that we can compute the errors on the measured values of σ t and σ a by performing a linear stability analysis of expressions (7). If t , respectively P , represents the temporal resolution, respectively the amplitude resolution, of the correlation setup, we obtain…”

“…It is the reason why many people, even in the telecommunication field, use the autocorrelation function to control the pulse shape [3]. But, even if the autocorrelation function has already been proved to be an efficient way to measure the timing jitter of 40-Gbit/s PRBS sequences [7] or the optical to noise ratio (OSNR) impairments at 10 Gbit/s [8], generally speaking, they do not pull all the benefits out of their measurements [3]. In this paper, we propose an extension of these methods and report an all optical technique for the simultaneous measurements of the intensity background, timing, and amplitude jitters of high speed repetition rate pulse trains or PRBS sequences.…”

Control of Soliton-trapping induced Timing Jitters by Polarization Modulation

“…Recently, more and more people pay attention to the soliton timing jitters. [7][8][9][10] In this paper, we suppose a new transmission control technique, using periodical polarization modulation to suppress the soliton timing jitters induced by random birefringence. II Normalized birefringence parameter 8 = (,1, -81 )To /2 121 describes the transmission mismatch between two polarization components due to fiber birefringence, where x1x and Ay are the transmission parameters of slow and fast polarization components.…”
