Abstract

A 200-Gb / s wavelength-division multiplexing transmission system using multiwavelength directly modulated transmitter optical subassemblies for data center has been proposed and demonstrated experimentally. The 8 × 25 Gb / s PAM-4 optical transmission system over 10 km of standard single-mode fiber is tested. The penalty variation within 1 dB for eight channels indicates that colorless transmission operation in the C-band is feasible with stable performance. Clear eye openings without any distortion show a good linearity characteristic for the optical transmission system. The advantages of integration, channelization, miniaturization, and low power consumption of the proposed scheme present a promising result for data center interconnection.
