Yano Research Survey on FTTH Service and Market Outlook for Optical Transmission Devices.Tokyo, Japan, Sept 26, 2006 - (JCN JCN Japan Corporate News JCN Journal of Cognitive Neuroscience JCN Journal of Cardiovascular Nursing JCN Journal of Christian Nursing JCN Job Control Number JCN Journal of Child Neurology JCN joint communications network (US DoD) ) - Yano Research Institute Ltd. today announced the results of survey it conducted on FTTH (Fiber To The Home) See FTTP. and optical transmission devices. Based on the survey, which was conducted from May to July of 2006, Fiber to The Home (FTTH) saw an overall decrease from the end of 2005 to 2006. However, with NTT's NGN (Next Generation Networks) An umbrella term for mixed voice and data networks running over the IP protocol. See IP Multimedia Subsystem. trial service, it is expected to rise from 2006 onwards. The market for optical transmission devices is about 190 billion yen. That number is expected to remain the same for the next few years, until 2011. CWDM (Course WDM) An optical transmission method that is used for shorter distances than dense WDM (DWDM). Also known as "wide WDM," CWDM transmits fewer channels and uses wider spacing between the channels for distances up to 60 km. Wider spacing up to 25 nm, compared to 1. devices are gradually increasing while WDM and SONET/SDH remain stagnant. Access equipment accounts for 76.2 billion yen of the market. Findings indicate that most major communication carriers use GE-PON, which is responsible for a 20% inclrease in market share over the previous year. Copyright [c] 2006 Japan Corporate News Network.
