Digital Back-propagation for Unrepeatered Transmission Invited
01:30-02:00
2017-10-03 01:30 2017-10-03 02:00 America/Denver Digital Back-propagation for Unrepeatered Transmission Unrepeatered transmission has seen a substantial advance in recent years, largely due to the development of advanced optical fibers and amplifier technologies. Here, the potential, limitations and practicalities of digital nonlinearity compensation to build on this development are explored. Hilton Santa Fe Historic Plaza Poinsettia/ Quince

Performance Limits of a Nonlinear Frequency Division Multiplexed System due to the Raman effect
02:00-02:15
2017-10-03 02:00 2017-10-03 02:15 America/Denver Performance Limits of a Nonlinear Frequency Division Multiplexed System due to the Raman effect The Raman effect causes higher-order solitons to break apart, leading to inter-symbol interference, even in the ideal case without propagation losses. The power threshold of this effect is 10 dBm for a two-eigenvalue QPSK system. Hilton Santa Fe Historic Plaza Poinsettia/ Quince

Timing Mismatch Tolerance of 16QAM OFDM Based Spectrum Slicing Optical Transmission Systems
02:15-02:30
2017-10-03 02:15 2017-10-03 02:30 America/Denver Timing Mismatch Tolerance of 16QAM OFDM Based Spectrum Slicing Optical Transmission Systems We propose an effective synchronization and digital signal processing scheme for OFDM spectrum slicing transmissions in the presence of large timing mismatches. Without loss of generality, a 76.8Gbaud DP-16QAM OFDM three-slice spectrum slicing system was considered. Hilton Santa Fe Historic Plaza Poinsettia/ Quince

Fiber-Optic Signal Processing Using Frequency Conversion for Optical Node Invited
02:30-03:00
2017-10-03 02:30 2017-10-03 03:00 America/Denver Fiber-Optic Signal Processing Using Frequency Conversion for Optical Node A concept for optical frequency rearrangement using frequency conversion is presented which is expected to increase the flexibility of optical path and spectral usage in optical nodes. We review experiments of coherent optical subcarrier processing and optical frequency shifter achieved by using highly nonlinear fiber. Hilton Santa Fe Historic Plaza Poinsettia/ Quince
