چکیده
Relative intensity noise (RIN) induced penalties were experimentally measured in distributed Raman amplifiers (DRAs) for G.654.E and G.652.D fibres with forward, backward bidirectional pumping configurations. The signal RIN using the fibre was ∼3.5 dB ∼2 lower than forward (FW) pump configuration PM-QPSK PM-8QAM signals, single span transmission showing a Q-factor improvement of ∼3 ∼2.5 over fibres. performance penalty long haul coherent system evaluated 28 GBaud signals recirculation loop amplifiers. Our experimental results demonstrate an additional distance more 1000 km its counterpart assuming HD-FEC limit 8.5 dB.

Hybrid Raman/Erbium-Doped Fiber Amplifiers for WDM Transmission Systems
As light pulses propagate along the optical fiber, their energy dissipates. Beyond a certain distance the number of photons in pulses becomes too small to be detected. The optical pulses in fibers are energized by utilizing optical fiber amplifiers. The rapid growth of the internet and data traffic in optical fiber communication networks has stimulated the study of wideband optical amplifiers. ...

To combine the benefits and compensate for the drawbacks of different optical amplifier types, a hybrid amplifier can be composed. The authors consider two most frequently used hybrid amplifiers that can provide better performance: a semiconductor optical amplifier (SOA), and an erbium doped fiber amplifier (EDFA), both in combination with a distributed Raman amplifier (DRA). To compare perform...

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
PMD induced transmission penalties in polarization multiplexed transmission
In this paper, we investigate for the first time chromatic dispersion and nonlinearity tolerances in the presence of polarization-mode dispersion (PMD) for polarization-multiplexed (POLMUX) 2 × 10-Gb/s nonreturn-to-zero (NRZ) transmission. In polarization-multiplexing, the interaction between fiber nonlinearity and PMD can lower the nonlinear tolerance beyond the tolerances evident when conside...
