or to an access point just outside the home, commonly referred to as fiber to the node or fiber to the curb. The technology allows for higher bandwidth and faster data transmission than any other connection type and has the unique capability of delivering symmetrical or near-symmetrical download...
A hybrid, low cost HUMS concept, based on fiber-optic point and distributed strain sensing for both usage monitoring and damage detection, is presented. Sensing is based on in-flight Fiber Bragg Grating (FBG) technology, combined with on-ground Rayleigh-backscattering distributed strain sensing. Th...
Transpacific TPC 4 (1992) was interconnected at Guam with PACRIM West and at Hawaii with PACRIM East, giving a wet connection to Australia and New Zealand. SEA-ME-WE 2 completed the loop around the world in 1994. Then, CANTAT 3 (2.5Gbit/s capacity per fiber pair) was the latest lo...

An improved waveguide for an infrared thermometer, comprising a silver halide optical fiber cable of low transmission loss, a high aspect ratio, and a radially decreasing index of refraction. The transmission loss is low enough to enable the cable to be up to ten meters in length, thereby exte...
A fiber optic-based all-optical amplifier is designed by using the coherent perfect absorption phenomenon. For this purpose, we use a deposited chromium thin layer as an absorbent material on the cross-section of a PM fiber. By placing another fiber in front of the deposited one, we show th...
Spectroscopic techniques have long been applied to the determination of analytical and bioanalytical measurements using fiber optic sensors; however, relatively few studies have been reported utilizing near-infrared (NIR) absorbing chromophores. This longer wavelength region of the electromagnetic spectrum is...
A loop that short-circuits this transmission line near the fiber tip with a diamond microcrystal (Figs 1 and 2) provides a microwave field distribution with a maximum at the location of the diamond microcrystal. Cell culture and transfection. HEK-293 cells (ATCC) were seeded into 35 ...

Introduction Photoacoustic tomography (PAT) is a powerful noninvasive and nonionizing biomedical imaging modality that has attracted great attention in the last ...
3-Mirror fiber optic sensor for simultaneous measurement of dual parameters such as hydrogen concentration and temperature, is formed from 2 optical leads comprising 3 reflective su
