Comparison of Coherent and IMDD Transceivers for Intra Datacenter Optical Interconnects
TL;DR: This work experimentally evaluated the performance of 400G coherent and IMDD transceivers for intra-datacenter interconnects, and showed that coherent transceIVERS can achieve a higher power budget with comparable ASIC power consumption.
Journal ArticleDOI
Open and disaggregated optical transport networks for data center interconnects [Invited]
TL;DR: This paper discusses technology developments that have enabled open optical transport networks, followed by a presentation of the open optical network architecture for DCI networks, and presents the data models of DCI equipment, including optical terminal transponders, point-to-point optical line systems, and ROADMs, developed based on OpenConfig YANG models.
Journal ArticleDOI
Carrier Phase Estimation Through the Rotation Algorithm for 64-QAM Optical Systems
TL;DR: In this article, a low-complexity two-stage digital feed-forward carrier phase estimation algorithm based on the rotation of constellation points to remove phase modulation for a 64-ary quadrature amplitude modulation (QAM) system is proposed and analyzed both experimentally and through numerical simulations.
Journal ArticleDOI

TL;DR: In this paper, a blind chromatic dispersion (CD) estimation method based on fractional Fourier transformation (FrFT) is proposed and demonstrated through numerical simulations, the proposed CD estimation method is shown to be robust against the amplified spontaneous emission noise and nonlinear interference.
Journal ArticleDOI
Pump RIN-induced impairments in unrepeatered transmission systems using distributed Raman amplifier
Jingchi Cheng,Ming Tang,Alan Pak Tao Lau,Chao Lu,Liang Wang,Zhenhua Dong,Syed Muhammad Bilal,Songnian Fu,Perry Ping Shum,Deming Liu +9 more
TL;DR: The vector theory of both 1st and higher-order stimulated Raman scattering (SRS) effect using Jones-matrix formalism is presented and an analytical model for the statistical property of relative phase noise (RPN) in higher order DRA without dealing with complex vector theory is derived.
