We experimentally demonstrate a 30 Gbaud 64 QAM transmission over 125 km of single span and 480 km of loop transmission with Kramers-Kronig direct detection using only a DFB laser and a single phot
In this Letter, we report on the design, optimisation and electrical measurements of the new multiplexing selector fabricated in 0.7-um InP double-heterojunction bipolar transistor (DHBT) technolog
We demonstrate a polarization division multiplexed (PDM) QPSK system at a record all-electronically multiplexed symbol rate of 180 GBaud, providing a line rate of 720 Gb/s on a single optical carri
We demonstrate PDM-QPSK transmission over 4480 km at a record all-electronically multiplexed symbol rate of 180 GBaud, providing a line rate of 720 Gb/s on a single optical carrier enabled by high-
We demonstrate the generation and coherent detection of 180-Gbaud QPSK using a 240-GSa/s, 100-GHz bandwidth digital-to-analog converter (DAC).
This letter presents a comparative study of GaInAs-AlInAs avalanche photodiodes with different absorption layer thicknesses.
Efficient, wideband and tunable optical wavelength conversion over 180 nm by four-wave mixing (Bragg scattering) in a fiber is demonstrated experimentally.
A BLAST/MIMO detector with 3.84 bit/s/Hz spectral efficiency supporting up to 4 x 4 QPSK MIMO is presented. The detector shows over a 5 dB improvement over VBLAST for an uncoded data system.
Information related to transmission performance of toll connections is essential to the evaluation of toll service quality, necessary for assessing the adequacy of present administrative and mainte
Data-Phone service was introduced on the switched network in 1959.
