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.
fiber optics. n. (used with sing. verb). 1. The science or technology of light transmission through very fine, flexible glass or plastic fibers. 2. A cable or network of cables containing optical fibers.
