In the past, the outside plant (OSP) to equipment fiber ratio was about two to one, or two OSP fiber terminations in the CO to every one equipment fiber termination. The focus for access and connections was primarily on the front of the optical distribution frame line-up. There was very little electronic equipment with optical interface – usually the last piece of equipment before the signal ex...

Visual inspection of fiber ends is often required during installation or maintenance of fiber optic cabling. Automated analysis first requires accurately determining the location of the fiber core. In this paper, we compare the accuracy and reliability of several different classifiers in finding the fiber core. Classifiers such as naive bayes, perception, and three layer feed forward neural net...

purpose: to evaluate the correlation between retinal nerve fiber layer (nfl) thickness and visual field parameters in patients with optic atrophy. methods: this study was performed on 35 eyes of 28 patients with optic atrophy. nfl thickness was measured by optic coherence tomography (oct) and visual field analysis was performed by humphrey perimetry. the correlation between nfl thickness and vi...

It is well known that phase noise fluctuations at the output of a semiconductor laser can produce intensity noise fluctuations upon transmission through a fiber-optic link due to interferometric phase-to-intensity conversion [1-4]. In a single-mode fiber link, the interferometric conversion occurs when multiple reflections occur between a pair of fiber interfaces (Figure 1). Even in the absence...

The objective of this paper is to provide a contemporary look at the current state-of-the-art in wireless sensor and fiber optic sensor for structure health monitoring (SHM) applications and discuss issue related to those system and hence, to make the efficient decision that provided the better system thinking. Specially, this paper provides review about structural health monitoring like, bridg...

EOAF 12004160 65 66 67 68 69 70 71 Abstract Fiber-optic sensors do not interfere with electromagnetic fields and are commonly used to measure temperature and pressure used in microwave and frequency heating research and applications. This article introduces the physical principles for three different types of commonly used fiber-optic sensors and discusses important parameters to be considered ...

BACKGROUND AND PURPOSE There is a well-known relationship between MS and damage to the optic nerve, but advanced, quantitative MR imaging methods have not been applied to large cohorts. Our objective was to determine whether a short imaging protocol (< 10 minutes), implemented with standard hardware, could detect abnormal water diffusion in the optic nerves of patients with MS. MATERIALS AND ...

It is significantly more challenging to extend the visibility factor a higher depth during development phase of communication system for subterranean places. Even if there are numerous optical fiber systems that provide right energy sources intended panels, parameter not optimized past certain point. Therefore, suggested method looks at properties optic integrated with source while having exter...

Fiber optic assemblies have been used on spaceflight missions for many years as an enabling technology for routing, transmitting, and detecting optical signals. Due to the overwhelming success of NASA in implementing fiber optic assemblies on spaceflight science-based instruments, system scientists increasingly request fibers that perform in extreme environments while still maintaining very hig...
