We demonstrate the use of MCF for power efficient ultra-high capacity long haul transmission. Feasibility of 105.1 Tb/s transmission over 14,350 km is shown using 12-core fiber and power equivalent of a single pump laser.
We demonstrate bidirectional pumped Raman amplification and 1050 km combined WD-M/SDM transmission in a 3-spatial-mode few-mode fiber with a 70-km zero-net-gain fiber span.
We demonstrate mode-multiplexed transmission over all-fiber optically amplified spans of 215 km and 179 km for 3 and 6 spatial modes, respectively. The spans were amplified using two cladding-pumped few-mode fiber amplifiers.
Using optimized hybrid Raman-EDFAs and coded modulation with variable spectral efficiency we achieve 54 Tb/s capacity over 9,150 km transmission. We also achieve a capacity-distance product of 534 Pb/s∗km after 10,230 km distance.
Two half-wavelength 122 GHz patch antennas were designed and manufactured by using Benzocyclobutene (BCB) as a dielectric layer above the SiGe BiCMOS wafer. It enables the full integration of the millimeter-wave transceiver circuits and the antennas on a single chip to simplify the packaging procedure at millimeter-wave frequencies, thereby reducing the cost. The two patch antennas are fed by different...
