Large-capacity satellite communication systems can be achieved by equipping both the satellites and earth stations with multiple-beam antennas.1 An offset Cassegrainian antenna (Fig.
A description of the latent development of the Pentaconta system, the first design (called Pentaconta 500) being installed in 1954.
The high reliability demanded of microwave radio relay systems requires t h a t protection be provided against system outages t h a t occur as a result of fading or equipment failures.
First demonstration of a symmetrical NGPON2 upgrade to 100G (4x25G) by using a novel very wavelength stable multi-electrode burst mode laser and electrical duobinary detection with 10G APD
We review recently demonstrated options for serial transport technologies at 100 Gb/s, including binary, multi-level, and coherently detected polarization-multiplexed formats.
To meet the exponentially growing bandwidth demand in optical transport networks, 100-Gb/s (100G) coherent technology based on polarization-division multiplexed quadrature phase shift keying (PDM-Q
After 40Gb/s been widely deployed in optical networks in China, 100Gb/s became the next focused technology.
Multiple access interfaces are required to provide the coverage and capacity that operators need for consistent service across their footprint.
We report on the use of semiconductor optical amplifiers to enlarge optical bandwidth of next generation optical systems.
We report on the ultra-wideband (UWB) transmission of a 103 nm signal over 3×100 km of standard single mode fiber (SSMF), a widely-deployed fiber in terrestrial transmission networks.
