A Novel MAMSK-OFDM technology for Next Generation Optical Access Networks
Novel MAMSK-OFDM technology Next Generation Optical Access Networks
2015/5/25
We propose and experimentally demonstrate a novel MAMSK-OFDM-PON. 5-Gb/s MAMSK-OFDM signal and 2.5-Gb/s upstream OOK signal is transmitted over 20km fiber successfully. The results show the prospect o...
System Requirements for WSS Filter Shape in Cascaded ROADM Networks
Optical switching devices All-optical networks Fiber optics optical communications
2015/6/8
We describe the impact of passband shape and random center frequency variations on the bandwidth narrowing caused by successive filtering in concatenated wavelength-selective switches. Passband flatne...
A Systematic Approach to Develop and Manage SRLGs for Optical Transport Networks with Multi-Tier Resources
General
2015/6/5
This paper presents a generalized framework that characterizes multi-tier resource dependency and operators’ diversity policies in transport networks. The framework enables the design of systematic ap...
The goals for ULH mesh network design should be reach optimization of the whole network and preparation for the future growth. We propose an approach that designs each ROADM-to-ROADM section independe...
Fortistis: Split Extension in Dense Passive Optical Networks by Inline Amplification with Remote ASE-Shaped Pump Delivery via Colorless Optical Network Units
Fiber optics communications Networks Multiplexing
2015/6/4
A method for extending the customer density via ASE-pumped splitters in the tree in a WDM/TDM-PON is presented. The influence of Rayleigh backscattering in the feeder is faced,originally prohibiting a...
Faults and Recovery Methods in Regional Undersea OADM Networks
Faults and Recovery Methods Regional Undersea OADM Networks
2015/7/17
An experimental study of faults in an important class of undersea OADM networks demonstrates that channel performance through surviving segments can be recovered by the terminal-based procedures enabl...
Broadband Convergence of 60-GHz ROF and WDM-PON Systems with a Single Modulator for Bidirectional Access Networks
Broadband Convergence ROF WDM-PON Systems Single Modulator Bidirectional Access Networks
2015/7/16
We experimentally demonstrated a converged 60-GHz ROF and 10-Gb/s WDM-PON system using an integrated modulator and a single wavelength for the first time. Orthogonal phase modulation is used to reliev...
Priority Encoding Scheme for Contention Resolution in Optical Packet- Switched Networks
Priority Encoding Scheme Optical Packet- Switched Networks
2015/8/6
A priority encoding scheme is introduced for an optical switching fabric testbed, resolving contention by dropping low priority messages. Optical packets with 6×10 Gb/s payloads are routed error-free.
Proactive Protection Based on Pre-FEC Statistics in pure IP Networks
Proactive Protection Pre-FEC Statistics pure IP Networks
2015/8/3
We extend the implementation of proactive protection to pure IP protection schemes and test its performance over a real DWDM system and additional failure modes: PMD injection and mechanical disconnec...
