Safety and reliability of control are foremost considerations for nuclear powerplants. as nuclear powerplant control becomes more distributed with next-generation intelligent sensors, integrated signal processors, and so forth, the need for more reliable plant-wide communication will become… More

Redundancy and fault tolerance are critical requirements in fiber optic networks used in distributed control systems. architectural design shortcomings in programmable control hardware and software areas could adversely impact the viability of programmable controllers in naval shipboard use, due to… More

Newly developed optical communication surveillance technologies provide both direct coupled and proximity tapping of fiber optic networks, without breaking or disrupting the optical characteristics of the media itself, resulting in virtually undetectable surveillance of the optical communication in… More

A fiber optic local area network (lan) development project is proposed to provide fault tolerant, secure shipboard communications. the lan will utilize phoenix digital's fault tolerant, "self-healing" fiber optic communications technology, in conjunction with gte's birefringent wavelength division… More

Dod optical communication requirements have moved beyond the performance capabilities of conventional fiber optic communication technologies. conventional optical communication networks are limited to baseband communication. however, breakthroughs in new, birefringent crystal technology combined… More
