An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other. Such fibers find wide usage in fiber-optic communications , where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables.
The plant is a warm season ornamental grass which typically grows in graceful, spreading clumps from 2–3 ft (0.61–0.91 m) tall and wide. It features narrow, medium to deep green leaves (to 1/2" wide) in summer, changing to golden yellow in fall, and fading to beige in late fall. The foliage usually remains attractive throughout the winter.
Pennisetum orientale, the oriental fountain grass, is a species of flowering plant in the grass family Poaceae, native to North West Asia and North Africa. Growing to 60 cm (24 in) tall and broad, this decorative perennial grass forms clumps with multiple tufted panicles up to 14 cm (5.5 in) in length. The panicles are pale pink, maturing to brown.
Many Pennisetum grasses are noxious weeds, including feathertop grass (P. villosum) and kikuyu grass (P. clandestinum), which is also a popular and hardy turf grass in some parts of the world. The herbage and seeds of these grasses are food for herbivores , such as the chestnut-breasted mannikin ( Lonchura castaneothorax ), the caterpillar of ...
Photonic-crystal fiber (PCF) is a class of optical fiber based on the properties of photonic crystals. It was first explored in 1996 at University of Bath, UK. It was first explored in 1996 at University of Bath, UK.
Hard-clad silica (HCS) or polymer-clad fiber (PCF) is an optical fiber with a core of silica glass (diameter: 200 μm) and an optical cladding made of special plastic (diameter: 230 μm). In contrast to all-silica fiber , the core and cladding can be separated from each other.
In Europe, Fountain grass is included since 2017 in the list of Invasive Alien Species of Union concern (the Union list). [6] This implies that this species cannot be imported, cultivated, transported, commercialized, planted, or intentionally released into the environment in the whole of the European Union.
When optical fibers are exposed to ionizing radiation such as energetic electrons, protons, neutrons, X-rays, Ƴ-radiation, etc., they undergo 'damage'. [1] [2] The term 'damage' primarily refers to added optical absorption, resulting in loss of the propagating optical signal leading to decreased power at the output end, which could lead to premature failure of the component and or system.
