Development and introduction of indoor optical cable using single-mode hole-assisted fiber in central offices

چکیده
We have realized a new optical cord with single-mode hole-assisted fiber (HAF) which has a superior bending loss that complies with ITU-T Recommendation G. 657 A2 & B3 for providing highly reliable optical fiber distribution facilities in central offices. The diameter of the new optical cord is 1.7 mm, and it can be detected with a conventional optical cord identifier despite its low bending loss. We have also developed new indoor optical cables employing new optical cords that achieve almost the same characteristics as conventional optical cable. A new indoor optical cable using the single-mode HAF was commercialized this year, and has been installed in a central office for the first time anywhere in the world.

Highly Reliable Optical Fiber Distribution Facilities in Central Office Employing Single-mode Hole-assisted Fiber Cord
We realized single-mode hole-assisted optical fiber (HAF) cord whose fiber has a superior bending loss characteristic that complies with ITU-T Recommendation G. 657 for use in highly reliable optical fiber distribution facilities in central offices. The cord has an excellent anti-shock characteristic, and can be detected with a conventional optical fiber cord identifier despite its very low ben...
متن کاملDesign Characteristic and Performance Analysis of Hole Assisted Fiber for Long Haul Optical Fiber Networks
In conventional photonic crystal fibers (PCF’s),the cladding structure is usually formed by air holes with the same diameter arrayed in regular triangular lattice. However, in index guiding PCF’s means in Hole Assisted Fiber, the periodicity in the cladding region is not essential to confine the guiding light in to the high-index core region. Hole Assisted Fiber (HAF) technology is investigat...
متن کاملMonte-Carlo Calculation of Radon Absorbed Dose in Optical Fiber as a Novel Method in Dosimetry and Radon Measurement
Introduction Radon is a colorless and tasteless gas which exists in most soils. It is a substance that poses a potential risk for lung cancer in case a person is exposed to high levels over long periods of time. The Environmental Protection Agency (EPA) estimates that 90% of lung cancers per year are caused by radon. The aim of this paper is to estimate the absorbed doses of 222Rn by MCNPX simu...
متن کاملOptimization of 3-hole-assisted PMMA optical fiber with double cladding for UV-induced FBG fabrication.
We propose a new hole-assisted polymer optical fiber design to eliminate the influence of dopant diffusion and to increase the UV writing efficiency in fiber Bragg grating inscription. The optical waveguide is formed inside a solid core surrounded by a ring of 3 large air holes in enhanced UV photosensitive PMMA with double-cladding. We determined a map of the single-mode and multi-mode phase t...
متن کاملDevelopment of a Disposable Electrochemical Sensor based on Nanocomposite/Ionic Liquid Assisted Hollow Fiber-Graphite Electrode for Measurement of Lorazepam Using Central Composite Design
In this study a new method of preconcentration, separation and efficient measuring of so-called hollow fiber solid / liquid phase microextraction has been introduced for the determination of trace amounts of lorazepam (LRZ) in water samples, urine and hair using differential pulse voltammetry. To this end, a hybrid adsorbent material was used that involved ionic liquid assisted magnetic multi-w...
