Newly introduced polarization diversity probing codes are suggested to enhance the sensitivity and bandwidth performance of differential-phase-sensitive distributed OTDR systems.
The availability of high brilliance synchrotron sources, coupled with recent progress in achromatic focusing optics and large area two-dimensional detector technology, has allowed us to develop an
This paper presents an experimental investigation of 40-Gb/s DWDM transmission technologies that can potentially transport multiple terabits of aggregate capacity with ultrahigh spectral efficiency
We report the first multi-channel transmission experiments at 160 Gb/s per wavelength in combination with pseudo-linear transmission in nonzero dispersion fiber.
We demonstrate combined wavelength- and mode-multiplexed transmission with a spectral efficiency of 58-b/s/Hz over an 87-km single-span multi-mode fiber using 16-QAM modulation format.
We demonstrate mode-multiplexed transmission over the first 9 mode group of 26 km long graded-index multimode fiber achieving a record spectral efficiency of 90 bit/s/Hz.
We discuss the impact of amplification technologies, multi- level constellations, and fiber nonlinearity of the spectral efficiency achievable in fiber-optic networks.
This paper reviews recent progress in high spectral efficiency optical transmission using probabilistic constellation shaping (PCS), and discusses various aspects of PCS from theoretic and practica
We discuss the concept of probabilistic shaping (PS) of constellations, and show that PS allows for flexibly tunable spectral efficiencies at improved transmission performance.
We review current technologies that enable mixed 10 G/40 G transmission in a single DWDM system to achieve capacity upgrade, and discuss promising technologies and challenges for transmitting 100-G
