Abstract

We experimentally investigate polarization-switched quadrature phase-shift keying (PS-QPSK) with a symbol rate of 37.3 GBd corresponding to a bit rate of 112 Gb/s. In a wavelength-division multiplexing (WDM) experiment with 50 GHz channel spacing, the transmission performance of PS-QPSK is compared to that of polarization-division multiplexed QPSK (PDM-QPSK) over an EDFA amplified ultra-large-effective-area fiber link. For a bit-error ratio (BER) of 3.8 × 10(-3), the achieved transmission distance is 11000 km for PS-QSPK and 10000 km for PDM-QPSK.

摘要

我们通过实验研究了符号率为37.3 GBd（对应比特率为112 Gb/s）的偏振切换正交相移键控（PS-QPSK）。在信道间距为50 GHz的波分复用（WDM）实验中，在掺铒光纤放大器（EDFA）放大的超大有效面积光纤链路上，将PS-QPSK的传输性能与偏振复用QPSK（PDM-QPSK）的传输性能进行了比较。对于误码率（BER）为3.8×10^(-3)的情况，PS-QSPK实现的传输距离为11000 km，PDM-QPSK为10000 km。
