Flattened Optical Multicarrier Generation Technique for Optical Line Terminal Side in Next Generation WDM-PON Supporting High Data Rate Transmission
TL;DR: First, optical line terminal (OLT) costs of conventional wavelength division multiplexed passive optical network (WDM-PON) system are reduced by introducing the proposed OMC source at OLT side of WDM-PONS system for large capacity WDM -PON that supports numerous users.
Journal ArticleDOI
Cross-layer design and ant-colony optimization based routing algorithm for low earth orbit satellite networks
TL;DR: Simulation results show that CAL-LSN performs well in balancing traffic load and increasing the packet delivery rate, and the end-to-end delay and delay jitter performance can meet the requirement of video transmission.
Journal ArticleDOI

Sibghat Ullah,Rahat Ullah,Qi Zhang,Hafiz Ahmad Khalid,Kamran Ali Memon,Adil Khan,Feng Tian,Xin Xiangjun +7 more
TL;DR: A new technique for generation of ultra-wide and flattened optical frequency comb (OFC) based on serial cascading of a phase modulator and dual-driven Lithium-Niobate Mach Zehnder modulator (DD-LiNbO3-MZM) is proposed.
Journal ArticleDOI
Optical frequency comb generation for DWDM transmission over 25- to 50-km standard single-mode fiber
Rahat Ullah,Liu Bo,Mao Yaya,Sibghat Ullah,Muhammad Saad Khan,Feng Tian,Amjad Ali,Ibrar Ahmad,Xin Xiangjun +8 more
TL;DR: In this article, DWDM-based differential quadrature phase shift keying modulated signals were successfully transmitted over SSMF and analyzed its transmission capability for range of 25 to 50 km with acceptable power penalties and bit error rates.
Journal ArticleDOI
Cost effective OLT designed from optical frequency comb generator based EML for1.22 Tbps wavelength division multiplexed passive optical network
TL;DR: In this article, a cost effective optical frequency comb (OFC) generator by using pair of Mach zehnder modulators (MZMs) in cascaded configuration with a single external modulated laser (EML) source, where the two MZMs were driven by low powered RF source with 30 GHz frequency by incorporating no extra electrical components.
