Phase Diversity Techniques for Coherent Optical Receivers
Abstruct-In the present state of the art, coherent optical receivers most often operate in the heterodyne mode. Here a photodiode-,amplifier combination having bandwidth greater than twice the bit rate ( B ) is needed: indeed bandwidths considerably greater than 2B are preferably employed to ease design of the bandpass filter needed for noise limitation, and to avoid demodulator penalties in so...
متن کاملTransmission simulation of coherent optical OFDM signals in WDM systems.
In this letter, we first present the theoretical basis for coherent optical OFDM systems in direct up/down conversion architecture. We then demonstrate the transmission performance through simulation for WDM systems with coherent optical OFDM (CO-OFDM) including the fiber nonlinearity effect. The results show that the system Q of the WDM channels at 10 Gb/s is over 13.0 dB for a transmission up...
متن کاملJoint Demapping and Decoding for DQPSK Optical Coherent Receivers
We present a low-complexity joint demapper-decoder scheme for coherent optical receivers with DQPSK modulation. The new technique reduces to 0.7dB the gap between QPSK and DQPSK in 100Gb/s coherent optical systems.
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...
متن کامل10,200km 22x2x10Gbit/s RZ-DQPSK Dense WDM Transmission without Inline Dispersion Compensation through Optical Phase Conjugation
Using optical phase conjugation with a polarization independent periodically-poled lithium-niobate subsystem, we demonstrate dense WDM 2x10Gbit/s RZ-DQPSK transmission over 10,200km of SSMF with a record accumulated dispersion, exceeding 80,000ps/nm. 2005 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (070.5040) Phase conjugation
