DTM is a fiber-optic network, based on bandwidth reservation and with support for dynamic reallocation of bandwidth. It is designed for real-time multimedia applications and for high-speed computer communication. DTM uses a novel medium-access technique and provides a multicast connection-oriented service. Several DTM networks can be connected into one large network. A prototype implementation ...

OBJECTIVE To evaluate the efficacy of fiber-optic phototherapy using the standard Ohmeda Biliblanket, a large version, double standard Biliblankets, and conventional phototherapy using daylight fluorescent lamps in full-term, healthy infants with nonhemolytic hyperbilirubinemia. METHODS Full-term, healthy infants with nonhemolytic hyperbilirubinemia (bilirubin concentration, >255 micromol/L o...

Fiber optic networks have recently become economically feasible for single households. Since the areawide expansion of fiber optic networks requires enormous financial resources, exact algorithms for finding provably-optimal solutions of the arising network design problems are desirable. We consider the problem of augmenting an existing network infrastructure by additional links (and switches) ...

In the fiber optic communication network for example,- FTTH, EPON, NBN, OTN and so on, most important components are length between transmitter receiver point. So, to make, cheap meaningful through optical it must be required calculate how what amount of signal is transmitted with given fiber. Finally, said that have several limitations like extension ratio. necessary investigate its affect on ...

The monitoring of transportation infrastructure health is currently reliant on transportation maintenance teams. Scheduled and periodic inspections of most infrastructures are performed by manual and visual operations, which are generally time consuming and costly procedures. The use of fiber-optic sensor technology makes it possible to realize continuous, real-time and automatic health monitor...

(Abstract) The health monitoring of smart structures in civil engineering is becoming more and more important as in-situ structural monitoring would greatly reduce structure life-cycle costs and improve reliability. The distributed strain and temperature sensing is highly desired in large structures where strain and temperature at over thousand points need to be measured simultaneously. It is d...

Fiber optic interferometry can be broadly explained as the techniques that utilize the fundamental principles of optical interference to measure physical sample properties or detect changes via sensing systems that are partially or completely realized using fiber optic components. While the field of optical interference dates back to second half of seventeenth century, the advent of fiber optic...

A fiber optic ultrasonic system is described which monitors the cure of an epoxy resin. Ultrasound is generated using a high-power optical fiber to deliver high-energy pulses of light to the prepared surface of an aluminum mold that contains the curing epoxy resin. The generated ultrasound is detected using a local fiber optic ultrasound sensor embedded in the curing epoxy resin. The system was...

Several major lung pathologies are characterized by early modifications of the extracellular matrix (ECM) fibrillar collagen and elastin network. We report here the development of a nonlinear fiber-optic spectrometer, compatible with an endoscopic use, primarily intended for the recording of second-harmonic generation (SHG) signal of collagen and two-photon excited fluorescence (2PEF) of both c...
