26x42.8-Gbit/s DQPSK Transmission with 0.8-bit/s/Hz Spectral Efficiency over 4,500-km SSMF using Optical Phase Conjugation
Employing optical phase conjugation with a polarization-diversity periodically-poled lithium-niobate subsystem, we experimentally demonstrate 42.8-Gbit/s RZ-DQPSK DWDM transmission with 0.8-bit/s/Hz spectral efficiency over 4,500 km of SSMF without inline dispersion compensation. Introduction Enhancing spectral efficiency (SE) is a suitable method to increase transmission capacity. Recently, st...
متن کاملExperimental Comparison of Optical Phase Conjugation and DCF Aided DWDM 2x10.7Gbit/s DQPSK Transmission
The performance of DWDM 2x10.7Gbit/s-DQPSK is assessed comparing mid-link optical phase conjugation (OPC) and DCF for dispersion compensation. We report a 44%-increase in transmission distance resulting from nonlinear phase noise reduction by using mid-link OPC. Introduction Mid-link optical phase conjugation (OPC) is an attractive method for replacing chromatic dispersion compensating fiber (D...

The compensation effects of number of fiber spans and the residual dispersion per span (RDPS) in the combining of dispersion management (DM) and the midway optical phase conjugation on the optical transmission link consisted of the long fiber spans with 94 km of SMF length and -160 ps/nm/km of the dispersion-compensating fiber’s dispersion coefficient for 24 channels x 40 Gbps wavelength divisi...
متن کاملEffective Fiber Optic Communication by Optical Phase Conjugation for a Multichannel System
-Optical communication is a form of telecommunication that uses light as carrier and optical fiber as a transmission medium. Optical communication meant for long haul communication has been intended for an eight channel Wavelength Division Multiplexing (WDM) system. Dispersion is the major effect present in the optical fiber which causes a broadening of pulses and leads to Inter Symbol Interfer...
