We demonstrate the transmission of 4 channels at 43Gb/s over a record 525km unrepeatered distance using PMD-tolerant and spectrally efficient PDM-RZ-BPSK modulation combined with a coherent receive

Short-reach communication systems use electro-optic transmission engines based on low-voltage, wide bandwidth modulators to achieve high capacity and low power operation.

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.

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.
