China starts anti-dumping probe into optical fibers from India BEIJING, Aug. 14 (Xinhua) -- China's Ministry of Commerce (MOC) announced Wednesday that it has launched an anti-dumping investigation into single-mode optical fibers imported from India. The investigation has been launched in response to a petition filed by the domestic industry, according to a statement posted on the MOC's website. The MOC will investigate whether Indian companies have sold single-mode optical fibers at an artificially low price in China and damaged Chinese businesses. The investigation is expected to last for one year, but it may be extended to Feb. 14, 2015, according to the statement. Single-mode optical fibers are mainly used in high-rate and long-distance transmissions for TV cables and Internet networks.
