Here we review the latest results on a proposed differential phase shift keying (DPSK) regeneration scheme exploiting a compact architecture based on a saturated semiconductor optical amplifier. The scheme allows for amplitude-only signal regeneration with limited excess phase-noise contribution. Both the pass-through (PT) and the four wave mixing (FWM) signals exhibit enhanced Q-factor and margin improvement in bit error rate vs receiver threshold measurements, making the configuration suitable for both wavelength-preserving optical regeneration and wavelength regenerative conversion. The regeneration through FWM has an higher resilience to noise than the PT and its polarization dependency can be eliminated with the implementation of a dual co-polarized pump scheme. Preliminary experiments of simultaneous regeneration of two DPSK data streams are also provided.","PeriodicalId":126687,"journal":{"name":"2015 Tyrrhenian International Workshop on Digital Communications (TIWDC)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114485713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, we did this theoretically and simulatively. We found that for PM-QPSK systems at full-C-band the reach increase may be substantial, on the order of 10%-25%, with optimum symbol rates on the order of 2-to-6 GBaud. We extended the investigation to PM-16QAM, where we found a qualitatively similar effect, although the potential reach increase is typically only about half that of PM-QPSK. We then set up an experiment to obtain confrmation of the theoretical and simulative predictions. We demonstrated a reach increase of 11% in a 19-channel, 128 Gbit/s per channel, PM-QPSK experiment, when going from single-carrier to multi-subcarrier (up to 16 subcarriers per channel) transmission. The experiment reached 14,100 km over PSCF, with 110 km spans and EDFA-only amplifcation. The results matched well the EGN model predictions.","PeriodicalId":126687,"journal":{"name":"2015 Tyrrhenian International Workshop on Digital Communications (TIWDC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125820943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonlinear interactions during propagation are another source of correlated phase noise. In this paper, we show through simulations and in experiments that blind decision-directed (DD) CPE with regular block lengths removes a large portion of the memory. This makes it virtually impossible in practice to quantify correlations that come from propagation effects, or to obtain rate gains by exploiting the nonlinear phase noise (NLPN). Larger CPE block lengths leave the memory partly intact. This, however, comes at the expense of reduced information rates. We are able to fully recover this rate loss in simulations by using idealized processing of phase distortions. In experiments with full DSP, an almost full rate recovery is reported.","PeriodicalId":126687,"journal":{"name":"2015 Tyrrhenian International Workshop on Digital Communications (TIWDC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116179225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
