Transmission of Multi-Band OFDM-UWB Signals along NG-FTTH Networks using Directly Modulated Lasers
Modulation Optical communications
2015/5/26
Transmission of multi-band OFDM-UWB signals along FTTH networks using directly modulated lasers is experimentally evaluated. Reach of 100 km of standard SMF is achieved with a BER below 10 -4 and an O...
Multi-band 16QAM-OFDM Vector Signal Delivery over 60-GHz DSB-SC Optical Millimeter-Wave through LO Enhancement
Multi-band 16QAM-OFDM Vector Signal Delivery 60-GHz DSB-SC
2015/5/21
For the first time, multi-band vector signal delivery over DSB-SC RoF system generated via single-stage optical upconversion has been accomplished through LO power enhancement, and was successfully de...
Significant Overhead Reduction of Multi-band Tb/s Coherent Optical OFDM Systems
Multi-band Tb/s Coherent Optical OFDM Systems Overhead Reduction
2015/5/15
The timing and optical laser phase of individual bands in multi-band OFDM are correlated. We significantly reduce the OFDM overhead through using FFT window synchronization for channel estimation and ...
110-Gb/s Multi-band Real-time Coherent Optical OFDM Reception after 600-km Transmission over SSMF Fiber
Fiber optics links subsystems Coherent communications
2015/6/8
We demonstrate real-time reception of a 110-Gb/s multi-band OFDM signal after transmission of 600-km SSMF fiber and 400-ps differential-group-delay. The performance of 110-Gb/s CO-OFDM signal is chara...
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...
High-sensitivity, Multi-rate,Multi-band OLT Receiver for Hybrid 1G / 10G Passive Optical Networks
High-sensitivity Multi-rate Multi-band OLT Receiver Passive Optical Networks
2015/8/3
An OLT receiver that includes a semiconductor optical amplifier, a “soft” optical filter and a PIN photodiode has significantly higher sensitivity, and lower complexity than avalanche photodiode-based...
