The loss of hollow-core Nested Antiresonant Nodeless Fiber (NANF) has been steadily decreasing lately, approaching that of standard Single-Mode Fiber (SMF). As for non-linear …
In the evolution of optical networks, spectral efficiency (SE) enhancement has been the most cost-efficient and thus the main driver for capacity increase for decades. As a result, the …

In optical networks, a connection (eg, light-path and light-tree) is set up to carry data from its source to destination (s). When the optical signal transmits through the fiber links and optical …
We propose an efficient three-step amplifier configuration algorithm to improve and maintain the generalized signal-to-noise ratio (GSNR) performance of dynamic C+ L-band links in …
Nonlinear interference (NLI) generated during the propagation of an optical waveform through the fiber depends on the fourth order standardized moment of the channel input …
