Dynamic Bandwidth Allocation in Flexible OFDM-based Networks
Dynamic Bandwidth Allocation Flexible OFDM-based Networks
2015/5/25
We propose a general policy to allocate subcarriers to time-varying traffic in a flexible OFDM optical network. We compare the OFDM network performance to that of a fixed-grid WDM network using simula...
40Gbit/s -tunable stacked-WDM/TDM-PON using dynamic wavelength and bandwidth allocation
Fiber optics communications Fiber optics components
2015/5/22
This paper proposes a configuration and a dynamic wavelength and bandwidth allocation for the upstream signal in 40Gbit/s -tunable stacked-WDM/TDM-PON. An upstream transmission experiment with...
Distance-Adaptive Spectrum Allocation in Elastic Optical Path ?etwork (SLICE) with Bit per Symbol Adjustment
All-optical networks Fiber optics links subsystems
2015/6/8
We present a concept of spectrally-efficient optical networking with distance-adaptive spectral allocation by adjusting the number of modulation levels. We demonstrate it by routing 40 Gb/s optical pa...
Photonic Network Optimization via Resource and LSPs Concurrent Allocation: a PCE+ Concept
Fiber optics optical communications Networks circuit-switched
2015/6/5
This paper proposes the concept of PCE+:a path computation element that performs a concurrent impairments aware routing and regenerator location for a WSON network using a fast analytical assessment o...
Multi-Band Power Allocation in AMOOFDM High data rate NG-PON downlink transmission direct modulation of linear laser
Fiber optics communications Modulation
2015/6/4
Multi-band power allocation for NG-PON downlink transmission is experimentally demonstrated when implementing AMOOFDM with direct modulation of a linear laser. Multi-user power and bit-allocation allo...
Channel-Allocation-Adaptive WDM Signal Observation Based on Sequential Ultrafast Field Sampling
Channel-Allocation-Adaptive WDM Signal
2015/7/20
A novel technology for simultaneous WDM signal monitoring is presented based on ultrafast field sampling. Its adaptivity for channel allocation and/or channel bandwidth is unique and attractive as is ...
TCP Friendly Active Optical Access Network Having Automatic Ranging and Slot Allocation Function
TCP Friendly Active Optical Access Network Automatic Ranging Slot Allocation Function
2015/7/17
A new optical access network using high-speed PLZT optical switch is presented. The access network,having automatic ranging and slot allocation fuction, can guarantee TCP throughput designing with fra...
