Advanced modulation formats combined with digital signal processing and direct detection is a promising way to realize high capacity, low cost power efficient short reach optical transmission system. In this paper, we present detailed investigation on the performance of three advanced for 100 Gb/s They are PAM-4, CAP-16 DMT. The required each format presented. Comprehensive simulations carried out evaluate in terms received power, transmitter bandwidth, relative intensity noise thermal...
We experimentally demonstrated 140-Gb/s transmission over 20-km standard single-mode fiber employing pulse-amplitude modulation (PAM)-4 and direct detection (DD) at 1.3 μm. DD faster than Nyquist is employed to compensate for channel impairments. The optimal length of taps decision directed least mean square the tap coefficient digital postfilter are investigated.

We developed the EDA-seq method, which enables simultaneous and quantitative detection of C, 5mC, 5hmC in DNA at single-base resolution.
Coal fly ash, a solid waste from powder plant, was fully used to produce sintered glass-ceramics by direct sintering in air after dry pressing at 10 MPa. The influence of particle size on the sinterability and properties had been systematically discussed. Compared with CFA (d50 = 12.6 μm), issued 20CFA 7.5 μm) 40CFA 4.9 higher bulk density, linear shrinkage lower porosity. activation energy obtained three sizes coal ash (CFA, 40CFA) were estimated density shrinkage, which 127, 102, 81 kJ/mol...
In this paper, we experimentally demonstrate single channel 128Gbit/s and four lanes transmission with a total capacity of 500Gbit/s for short reach applications employing PAM4 format direct detection commercial 25Gbps devices.
Infrared (IR) and visible images are heterogeneous data, their fusion is one of the important research contents in remote sensing field. In last decade, deep networks have been widely used image due to ability preserve high-level semantic information. However, lower resolution IR images, learning-based methods may not be able retain salient features images. this article, a novel based on Features & Multiscale Dense Network (IR-MSDNet) proposed content key target from both fused image. It...
Rolling bearings are prone to failure due the complexity and serious operational environment of rotating equipment. Intelligent fault diagnosis based on convolutional neural networks (CNNs) has become an effective tool ensure reliable operation rolling bearings. However, interference caused by environmental noise variable working conditions can affect data. To solve this problem, we propose improved method called deep network multi-scale features mutual information (MMDCNN). In our approach,...
Comprehensive Summary 5‐Methylcytosine (5mC) plays pivotal roles in numerous biological processes. To gain a deeper understanding of the functions 5mC, it is essential to develop methods for its quantitative analysis. Herein, we engineered repressor silencing 1 (ROS1) protein enhance glycosylase/lyase activity towards resulting an ROS1 (eROS1) that can effectively excise 5mC from DNA. Using eROS1, developed method termed ROS1‐mediated (eRMQ) analysis, locus‐specific quantification genomic...
We proposed a novel 100Gb/s PON scheme using 4-PAM modulation with commercial low-cost 10Gbps TOSA/ROSA compatible 40Gb/s TWDM-PON. Experimental results show that EQ compensating bandwidth limitation and CD, 30km transmission is available.
Polarization-division-multiplexed (PDM) four-level pulse amplitude modulation (PAM4) with coherent detection is a promising low cost solution for 80 km inter-datacenter transmissions at 100 Gb/s and beyond. In this paper, three modified adaptive equalization algorithms the PDM-PAM4 optical systems, i.e. signal-phase aid least-mean-square (SP-LMS) algorithm, training multi-modulus algorithm (TMMA) cascaded four-modulus (CMMA-4), are proposed compared. Based on algorithms, 112 transmission...
