Control Orchestration Protocol: Unified Transport API for Distributed Cloud and Network Orchestration

In the context of the fifth generation of mobile technology (5G), multiple technologies will converge into a unified end-to-end system. For this purpose, software defined networking (SDN) is proposed, as the control paradigm will integrate all …

Demonstration of Virtualizeable and Software-Defined Optical Transceiver

In order to serve the future high-performance network-based Internet applications, optical network virtualization is proposed to offer each application type a dedicated virtual optical network (VON). Virtualizeable bandwidth variable transceiver …

SDN-Enabled Sliceable BVT Based on Multicarrier Technology for Multiflow Rate #x002F;Distance and Grid Adaptation

We propose a sliceable bandwidth variable transceiver (S-BVT) architecture suitable for metro/regional elastic networks and highly scalable data center applications. It adopts multicarrier modulation, either OFDM or DMT, and a cost-effective …

Demonstration of Optical Virtualize-Able Transceiver Using Extended OpenFlow Control

A feasible optical virtualize-able transceiver is proposed to support virtual optical networks by creating multiple co-existing virtual transceivers controlled by SDN. This solution is experimentally demonstrated, showing on-demand selection of …

Real-Time Ethernet to Software-Defined Sliceable Superchannel Transponder

Optical Ethernet gains great success in varied optical domains. Ethernet while providing the elastic allocation of bandwidth per flow is currently restricted to being transported over fixed-rate fixed-grid optical channels. However, as data …

Chirp and Frequency Offset Tolerant Coherent Burst-Mode Receiver Using Directly Modulated DFB Lasers for Coherent PON Systems

Burst-mode receiver (BMR) is one of the key components in passive optical networks (PONs). When directly-modulated distribution feedback (DFB) lasers are used as transmitter source, the BMR needs to take additional measures to compensate the effects …

Generation of 64-QAM Signals Using a Single Dual-Drive IQ Modulator Driven by 4-Level and Binary Electrical Signals

A simple square 64-QAM generation technique using a commercially available dual-drive IQ modulator driven by 4-level and binary electrical signals is proposed. Polarization multiplexed (PM) 64-QAM signals at 20Gbaud/s are experimentally demonstrated.
