This 5 GHz CMOS radio transceiver front-end chipset for wireless LAN applications incorporates the direct conversion architecture and is implemented in 0.25 μm CMOS.
A novel 3-PSK modulation format with 2 dB SNR gain according to information theory over BPSK has been implemented for ultra long haul transmission.
All-Raman transmission of 128 x 42.7 Gb/s at 50 GHz channel spacing over 1280 km of Standard Single-Mode Fiber is demonstrated.
In this paper we present two ICs fabricated in InP DHBT technology and devoted to 43 Gbit/s and over transmission systems : reshaping DFF for the transmitter and decision circuit for the receiver.
With the combination of Tomlinson-Harashima precoding and Volterra equalization, we successfully transmit 28 GBd PAM-4 signal over 80-km chromatic dispersion uncompensated fiber link, achieving a B
Optical data links are the backbone of today's telecommunication infrastructure.
We achieved 34 dB optical power-budget with low-complex 50 Gbps EDB BM coherent detection using 11 GHz PINs and BM friendly equalization.
Investigation of neural networks as Rx equalizer for 50 Gbps IM/DD TDM-PON. The NN is optimized specifically for PON with respect to differential reach and wavelength variations between ONUs.
Extended reach up to 60km for 50G NRZ and 20km for 100G NRZ downstream PON based on optical duobinary and simple 25G class APD-based detection is shown.
We report the first successful demonstration of quadrature phaseshift keying (QPSK) modulation using two nested silicon Mach-Zehnder modulators.
