New Test allows transfer of data at 16.4 Tbps Over 1,500 Miles
The goal of 100 Gbps Ethernet transmission is closer to reality with the announcement Wednesday that Alcatel-Lucent researchers have recorded an optical transmission record along with three photonic integrated circuits. New technology was used including a highly linear, balanced optoelectronic photoreceiver and an ultra-compact, temperature-insensitive coherent mixer.” Research was Carried out by researchers in Bell Labs in Villarceaux, France and researchers utilized 164 wavelength-division multiplexed channels modulated at 100-Gbps in the effort. The three papers described the development of different components useful in achieving 100 Gbps, including an integrated high-speed receiver, a dual-polarization modulator, and another modulator used for systems with extremely high spectral efficiency.
