ANORO is only approved for use in COPD. ANORO is NOT approved for use in asthma. People with asthma who take long-acting beta 2-adrenergic agonist (LABA) medicines, such as vilanterol (one of the medicines in ANORO), have an increased risk of death from asthma problems. It is not known if LABA medicines increase the risk of death in people with COPD.
An optical fiber (or optical fibre) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.n optical fiber doped with certain rare earth elements such as erbium can be used as the gain medium of a laser or optical amplifier. Rare-earth-doped optical fibers can be used to provide signal amplification by splicing a short section of doped fiber into a regular (undoped) optical fiber line.
Optical fibers typically include a transparent core surrounded by a transparent cladding material with a lower index of refraction. Light is kept in the core by the phenomenon of total internal reflection which causes the fiber to act as a waveguide.ptical fibers are connected to terminal equipment by optical fiber connectors. These connectors are usually of a standard type such as FC, SC, ST, LC, MTRJ, or SMA, which is designated for higher power transmission.
