Performance Degradation of 100 Gb/s PM-QPSK and 400 Gb/s PM- 16QAM Single Carrier and Dual Carrier Coherent Systems Due to Cascaded Optical Filters
ABSTRACT In this paper, we studied the performance degradation of single-carrier and dual-carrier 100 Gb/s and 400 Gb/s systems due to optical filter cascade with 50 and 100/150 GHz channel spacing, respectively. Eye closure penalty (ECP) is used as a performance evaluation metric, where we use two types of filters: fiber Bragg grating (FBG) and thin-film filters (TFF). Simulation results indic...
متن کاملQuasi Real-Time 230-Gbit/s Coherent Transmission Field Trial over 820 km SSMF Using 57.5-Gbaud Dual-Polarization QPSK
We demonstrate 230-Gbit/s (57.5-Gbaud) polarization-multiplexed QPSK coherent transmission over 820 km field-installed SSMF with quasi real-time DSP, without resorting to ETDM. BER performance well below FEC error-free threshold (2×10) at 2-1 PRBS length was achieved. OCIS codes: (060.1660) Coherent communications; (060.2330) Fiber optics communications
متن کاملPerformance of PM QPSK and PM 16-QAM coherent optical fiber communication systems
The performance of polarization multiplexed, quadrature phase shift keying (PM QPSK) and polarization multiplexed 16-ary quadrature amplitude modulation (PM 16-QAM) is considered with an emphasis on the signal processing algorithms that compensate transmission impairments and implement key receiver functions.
متن کاملStochastic BER estimation for coherent QPSK transmission systems with digital carrier phase recovery.
We propose a stochastic bit error ratio estimation approach based on a statistical analysis of the retrieved signal phase for coherent optical QPSK systems with digital carrier phase recovery. A family of the generalized exponential function is applied to fit the probability density function of the signal samples. The method provides reasonable performance estimation in presence of both linear ...
متن کاملTransmission of PM-QPSK and PS-QPSK with different fiber span lengths.
We perform experimental and numerical investigations of the transmission reach of polarization-switched QPSK (PS-QPSK) and polarization-multiplexed QPSK (PM-QPSK) for three different fiber span lengths: 83, 111 and 136 km. In the experimental comparison we investigate the performance of PS-QPSK at 20 Gbaud and PM-QPSK at the same bit rate (60 Gbit/s) and at the same symbol rate, both the single...
