Description

The dataset consists of simulated waveforms and eye diagrams captured at both transmitter (Tx) and receiver (Rx) ends, aiming to assess transmission performance across various operational temperatures of the vertical-cavity surface-emitting laser (VCSEL)-based Tx (25, 55, and 85 °C). 

Specifically, at the Tx-end, the simulation data are enhanced with captured spectra at the VCSEL-based Tx output. For each temperature, the peak-to-peak voltage of the RF electrical input was set at 200 mV, operating at 50 GBaud with an OOK-NRZ modulation format. This peak-to-peak voltage was selected in order to align with the performance of a typical network interface controller. In addition, the chirp factor of the VCSEL-based Tx was set at 10 and 12.

Following this, the transmission performance was examined across fiber lengths of 500 m and 1 km. The exported data focused on capturing the simulation results at three critical stages of the transmission: a) during the generation of the RF 50 GBaud OOK-NRZ signals, b) at the VCSEL output, and c) during the reception of the electrical signal at the Rx-end (transimpedance amplifier (TIA) output). The devices that impose the bandwidth limitations and are investigated in these simulations, were: the laser driver, VCSEL, photodiode, and TIA. 

Abstract

The dataset comprises raw simulation data concerning waveforms and eye diagrams of 50 Gb/s OOK-NRZ signals at various stages, both at the transmitter (Tx) and receiver (Rx) ends.

This version is further enhanced with spectra data captured at the Tx-end.

These simulations were conducted to assess the transmission performance of the Module-1b SPRINTER prototype, which facilitates a 200 Gb/s aggregated capacity and supports the generation and detection of four 50 GBaud OOK-NRZ signals. The dataset is presented in *.csv format and encompasses results obtained for various operational temperatures of the Tx-side. Additionally, this version contains simulation data for different chirp factors at the Tx end. These evaluations were conducted during transmission through a standard single-mode fiber across for two different fiber lengths (500 m & 1 km).
