We achieved the lowest-ever transmission losses of 0.1419 dB/km at 1560 nm wavelength
and 0.1424 dB/km at 1550 nm in a Ge-free silica-core optical fiber. It was an improvement by …

Next-generation optical communication systems will continue to push the (bandwidth·
distance) product towards its physical limit. To address this enormous demand, the usage of …

Record-low loss of 0.149 dB/km at 1550nm is realized by pure-silica-core fiber having
optimally enlarged Aeff, which indicates record-high figure-of-merit for digital coherent …

A novel six-core few-mode fiber is proposed in this paper. The refractive index of each core
is graded and pure silica is adopted in the center of each core. Four supermodes are …

Scaling up cable capacity in a power-and cost-efficient manner is a goal of spatial-division
multiplexing (SDM) in long-haul optical communication systems. Integration is a key to …

This paper investigates the transmission performance of a 1.55-Tb/s Nyquist-wavelength
division multiplexing superchannel along with a mixed line rate approach using 4× 111 Gb/s …

Digital signal pre-processing at the transmitter is a key enabler for next-generation optical
transceivers. One of the major challenges faced by these transponders is the limited …

Analytical OSNR formulation is developed and validated with 100G-DP-QPSK-WDM
experiments. Considering EDFA-output limitation, span length is optimized for subsea …
