Single-VCSEL 100-Gb/s Short-Reach System Using Discrete Multi-Tone Modulation and Direct Detection

Abstract

We demonstrate an up to 115-Gb/s line-rate short-reach system using a single 1550-nm VCSEL with discrete multi-tone modulation and direct detection, which can cover 500-m to 4-km standard-single-mode fiber at 95-Gb/s to 105-Gb/s bit rates.
