Fiber Nonlinearity Mitigation by Short-Length Probabilistic Constellation Shaping for Pilot-Aided Signaling
The reason for this behavior is that short-length PCS implicitly induces some temporal properties in the shaped transmit sequence that are beneficial for the fiber-optic channel.
56 Gb/s DMT Transmission with VCSELs in 1.5 um Wavelength Range over up to 12 km for DWDM Intra-Data Center Connects
We demonstrate up to 12 km, 56 Gb/s DMT transmission using high-speed VCSELs in the 1. 5 um wavelength range for future 400Gb/s intra-data center connects, enabled by vestigial sideband filtering of the transmit signal.
Solutions for 400 Gbit/s Inter Data Center WDM Transmission
We review some currently discussed solutions for 400 Gbit/s inter-data center WDM transmission for up to 100 km.
Optimizing Discrete Multi-tone Transmission for 400G Data Center Interconnects
It can be seen that an FFT length of 128 is sufficient to reach the required performance in terms of bit error ratio, however, a higher length can significantly improve the performance.
Practical Solutions for 400 Gbit/s Data Center Transmission
We review three solutions for low-cost data center interconnects with a target reach of up to 80 km.
Solutions for 80 km DWDM Systems
We review currently discussed solutions for 80 km DWDM transmission targeting inter data-center connections at 100G and 400G line rates.
Flexible bandwidth 448 Gb/s DMT Transmission for Next Generation Data Center Inter-Connects
We experimentally evaluate a flexible DMT system using 4 to 8 50-GHz-grid C-band channels to transmit 448 Gb/s over up to 240 km SSMF.
Experimental Investigation of Discrete Multitone Transmission in the Presence of Optical Noise and Chromatic Dispersion
Enabled by channel adaptive bit and power loading, we experimentally demonstrate discrete multitone transmission at 56Gb/s with simple intensity modulation and direct detection and achieve 50 km reach in the 1. 55um window.
Real-time 112 Gbit/s DMT for Data Center Interconnects
We report on 112 Gbit/s real-time DMT transmission over up to 60 km, targeted at DCI applications.
64 GBd DP-Bipolar-8ASK Transmission over 120 km SSMF Employing a Monolithically Integrated Driver and MZM in 0.25-um SiGe BiCMOS Technology
We demonstrate 64 GBd signal generation up to bipolar-8-ASK utilizing a single MZM, monolithically integrated with segmented drivers in SiGe.
Metro-haul Project Vertical Service Demo: Video Surveillance Real-time Low-latency Object Tracking
We report on the EU H2020 project METRO-HAUL use-case demonstration, including flexible allocation of storage and computing resources in different network locations and deployment of a network slice instance through a programmable multi-layer optical network.
Real-time discrete multi-tone transmission for passive optical networks in C- and O-band
DMT at 25 Gbit/s, 50 Gbit/s and 100 Gbit/s in passive systems with electro-absorption modulators is investigated.
