“…On the other hand 0 >= ⋅ < β α corresponds to the complete random correlation between the PMD and PDLG polarization direction, which could be realized in ultra-long-haul links where many components are interleaved. In our calculations we choose 15 . 0 .…”

“…Polarization mode dispersion (PMD), as one of polarization effects, is recognized by many researchers as one of the significant factors that limits the longhaul links [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Polarization dependent loss or gain (PDLG) is another important polarization effect that needs to be considered with PMD as the network complexity increases.…”

We give an analytical expression to evaluate the optical eye diagram due to polarization-mode dispersion (PMD), polarization-dependent loss (PDL), and chromatic dispersion (CD) for a system of highly mode coupled fiber with lumped section at any given optical pulse sequence. We found that with considering PDL and the polarization direction correlation between PMD and PDL, a system with highly mode coupled fiber and lumped section can have either higher or lower Q-factor than a highly mode coupled system with same root mean square PDL/PMD values. Also we noticed that a system of two highly mode coupled fibers connected together is not equivalent to a system of highly mode coupled fiber when fluctuation is considered.

“…These values exhibited temporal changes of about 10% in a day. There were some reports on statistical characteristics of installed fiber cables [2,8]. These papers showed that the temporal variation of DGD in installed fiber cables which had been buried under ground would be quite slow.…”

“…These papers showed that the temporal variation of DGD in installed fiber cables which had been buried under ground would be quite slow. Typical variation interval was about a few days or a week [2,8]. As the typical time period which is used to carry out power penalty measurements is short compared to these DGD fluctuations, system performance is measured at static values for DGD and principal state of polarization (PSP).…”

“…As for fibers that have been installed some years ago polarization-mode dispersion (PMD) is a critical issue for the transmission of 40-Gbit/s wavelength channels [2,3], during our joint field trial NTT and DT have mainly focussed on the impact of PMD on OTU3 transmission. A typical statistical distribution of PMD values in DT's fiber network is given in Fig.1 illustrating the importance of focusing on strategies to overcome PMD for 40G long haul applications.…”

A joint field trial on 40G transmission was conducted, where Deutsche Telekom's and NTT's R&D groups got involved. 43-Gbit/s/ch CS-RZ signals of the NTT G.709-OTN system were transmitted over selected high-PMD fiber links in DT's actual field environment. The advantage of CS-RZ modulation format was confirmed in comparison with conventional NRZ against all-order (first-and higher-order) PMD. Moreover, we introduced a new scheme for an accelerated determination of outage probability due to PMD that is adapted to practical field conditions in an operated fiber network with buried fibers and in-line operational optical elements.
