We report the first successful real-time superchannel trials up to 5.6Tb/s over 359km and 2Tb/s over a live 727km link using 64GBaud flexible-rate transponders, demonstrating long term error-free performance and fast capacity turn-up of ∼2Tb/min.
Hybrid access network integrated with multi-level wireless vector signal and wireline OOK signal without optical filter is proposed for the first time. 312.5-MSymbol/sec RF 8-PSK signal and 1.25-Gb/sec BB signal are experimentally demonstrated.
A coherent receiver with feedback was developed to linearly demodulate the phase of an analog signal. The receiver demonstrates a spur-free dynamic range of 125 dBmiddotPHz2/3 at a signal frequency of 300 MHz.
The generation of optical millimeter-wave with frequency 8-tupling is experimentally demonstrated. 625-Mb/sec QPSK data transmission at 105-GHz (W-band) is achieved for the first time using the millimeter-wave generation technique and direct modulation of a NBUTC-PD.
A novel 60-GHz photonic millimeter-wave signal generation using a frequency quadrupling technique is proposed for the first time. A 312.5-MSym/s 8-QAM millimeter-wave signal at 60 GHz is demonstrated with negligible penalty following 25-km SMF transmission.
We experimentally demonstrate 10-Gb/s OFDM-QPSK signal with negligible penalty following 100-km SSMF transmission within 7-GHz unlicensed band at 60-GHz for the first time. The proposed scheme proves to be a viable solution for long-reach 60-GHz RoF system.
Both highly spectral-efficient direct-detection 15-Gb/s 64-QAM and 20-Gb/s 16-QAM OFDM signals are demonstrated. Negligible penalty is observed following 25-km SMF transmission.
A multi-services hybrid access network has been experimentally demonstrated. The scheme has no RF fading issue; can carry vector signals, and requires no optical filter at remote nodes.
The paper presents the design and experimentation of a high-performance optical packet-switched metro WDM ring network (HOPSMAN). Equipped with novel medium access control, HOPSMAN achieves superior bandwidth efficiency, access delay, fairness, and bursty traffic adaptation.
Transient amplifier gain excursion of surviving channels due to dynamic wavelength add-drop should be kept below 1.5 dB to maintain data quality and receiver clock synchronization. This is experimentally demonstrated with 800 km-span of field deployed fiber network.
