This paper explores the merits of the single-path selective-broadcast interconnection (SBI) implemented in fiberoptic technology. This is a static, passive, fiber-optic interconnection among a set of stations, each equipped with multiple, say r , transmitters and receivers. It employs c 2 buses, each interconnecting a subset of the stations, and provides a single optical path between any two st...

Fiber optic sensor technology offers the possibility of sensing different parameters like strain, temperature, pressure in harsh environment and remote locations. these kinds of sensors modulates some features of the light wave in an optical fiber such an intensity and phase or use optical fiber as a medium for transmitting the measurement information. The advantages of fiber optic sensors in c...

Fiber loop ringdown (FLRD) utilizes an inexpensive telecommunications light source, a photodiode, and a section of single-mode fiber to form a uniform fiber optic sensor platform for sensing various quantities, such as pressure, temperature, strain, refractive index, chemical species, biological cells, and small volume of fluids. In FLRD, optical losses of a light pulse in a fiber loop induced ...

This paper discusses our experience in implementing the Xpress Transfer Protocol. XTP is a transport and network layer protocol suitable for use as a Safenet Transfer Service in the Navy’s emerging SAFENET specification. We describe the background of SAFENET and XTP, the essential features of the protocol, our implementation environment, our communications architecture, the user interface, a de...

This work presents ZnO nanorods coated multimode optical fiber sensing behavior in response to ethanol solution. The sensor operates based on modulation of light intensity which arises from manipulation of light interaction with the ambient environment in sensing region. For this purpose, two steps are experimentally applied here; etching and then coating fiber with ZnO nanorods to provide stro...

Thermonuclear reactors will require permanent monitoring under high-gamma dose rates and high neutron flux. We propose to get rid of the digital data transmission limitations in highly radioactive environments by implementing an analog fiber-optic link based on directly modulated vertical-cavity surface-emitting laser (VCSELs). In this paper, we introduce an architecture for highly radiation-to...

Compare with traditional way of numerical simulation by establishing the mathematical model through geometry optic, we design a TracePro model to analyze the sensing process of reflective intensitymodulated fiber optic sensor base on ray tracing. This type of sensor has advantages over other fiber optic sensor, including simple structure, flexible design, reliable perform, low cost etc. In this...

In the present paper, a theoretical analysis for predicting the effect of temperature on the performance of a fiber optic SPR sensor has been carried out. The sensor configuration is a three layer Krestchmann configuration consisting of fiber core, thin metallic layer, and bulk sensing layer. The optical fiber considered is a multimoded fiber. The effect of temperature is included in terms of t...
