Based on Tomlinson-Harashima precoding, we demonstrate 84 GBd PAM-4 transmission in an intensity-modulation direct-detection system with 33 GHz brick-wall bandwidth limitation.
In this Letter, we report on the architecture and performances of multilevel driver for Pulse Amplitude Modulation (PAM) formats, designed and fabricated in 0.7-um InP double-heterojunction bipolar
We report on an 85.4 Gbit/s ETDM transmission system with implemented ultra-FEC.
We demonstrate error free 85.4 Gbit/s ETDM VSB transmission over 2 km without dispersion compensation and optical amplification.
We present the results of an 8x107 Gbit/s ASK-NRZ-VSB DWDM field transmission trial in the fiber network of Deutsche Telekom.
We demonstrate error free 8x107 Gbit/s DWDM serial binary NRZ VSB transmission over 480 km SSMF without using an optical equalizer. A spectral efficiency of 1bit/s/Hz is achieved.
We demonstrate a 2-Tbs WDM transmission at 1550nm with digital carriers over a record span length of 200km, in which each channel carriers 256Gbps, detected by a single photodiode using either Kram
8 times 107 Gbit/s DWDM transmission is achieved over a 500 km field installed fibre link in the Deutsche Telekom network, indicating high link utilization of 1 bit/s/Hz spectral efficiency, needed
We demonstrate 8×215Gbps net-data-rate WDM transmissions at 1550nm with virtual carriers over a record span length of 200km, in which each channel was detected by a single photodiode with either Kr
High frequency characterisation of three-quantum well GaInNAs/ GaAs lasers operating at 1.35 mum is reported.
