“…In addition, they tap the optical signal reducing the effective receive power [1] [2]. In [3] a state based OPM with simultaneous estimation of CD, OSNR and non-linearities was shown, which could be cost-effectively realized as a by-product in direct detection receivers with equalization by MLSE.…”

KG, Hofmannstr. 51, D-81379, Munich, Germany Abstract: We present a robust and precise optical performance monitoring technique from FIR filter coefficients in coherent receivers with digital equalization. Residual chromatic dispersion, DGD and OSNR are simultaneously estimated from measured 111 Gbit/s data.

“…CD can be estimated by inserting training symbols or specific bit sequences [10] but the length of pilot symbols needs to grow with CD and may become prohibitive for links approaching 100,000 ps/nm of CD. On the other hand, blind non-data aided (NDA) CD estimation is often required/preferred [11] for equalizer initialization but they need to be insensitive to other impairments, independent of modulation formats and needs to be fast. To this end, we proposed to use the auto-correlation of received signal power waveform [13] …”

“…After coherent detection, with the aid of the received spectra and the known transmitted ©Optical Society of America spectra of the TS, a low-complexity channel estimation can be obtained by simply inverting the estimated channel transfer function. From the filter transfer function CD, PMD and PDL information can be retrieved [10,11]. Although CD and PMD estimation provides same performance for both DA zero-forcing (ZF) and minimum-mean square-error (MMSE) filter implementation [7], PDL estimation should be based on the ZF solution.…”
