The amplification of multiple optical channels has increased the distance between electrical regenerators almost an order of magnitude and has reduced long-haul transmission costs...
It would be impossible to design and simulate microprocessors without very powerful CAD programs to model microelectronic circuits and structures. Likewise the photonics industry...
Lensed and tapered specialty fibers are designed to optimize coupling between the fiber and optical components such as edge-emitting laser diodes and the waveguides in an integrated...
The evolution to higher data rates such as 40 Gbit/s requires a number of new engineering solutions. Among them is a change to return-to-zero (RZ) coding format. As with all technical...
Fibers may take a more active role in future communications systems if a new class of devices proves successful. A recent collaboration by Lucent Technologies and OFS Laboratories...
Researchers at NTT Photonics Laboratories in Ibaraki, Japan, have invented an arrayed-waveguide device that operates over a wide wavelength range, produces a stable, narrowband...
The technique of interleaving wavelengths is an effective way to narrow e×isting 200- or 100-GHz DWDM systems down to 50-, 33-, or 25-GHz channel spacing. To accomplish this goal...
Simon Lui is first deputy general manager of Wuhan Telecommunication Devices in Wuhan, China. He received his undergraduate degree in marketing and a master's degree in management...
How are you? In any language, the question is usually a casual form of greeting and the person posing it doesn't expect a real answer. Yet these days it is the question that we...
Band WDM products utilize proprietary thin-film filter technology to achieve wavelength and channel isolation and stability. The 100- and 200-GHz (4 Skip 0) Band WDM products ...
Falling prices coupled with a market slowdown during the last 18 months have driven a major shift in component manufacturers' priorities. Reducing production costs has replaced...
