(attach a separate page as annex, if necessary) The optoelectronics assembly technology has been in progress and the need of standardization is high. Some components are available in the market for production and/or development of various systems requiring very high speed signal processing. TC91 made a resolution that it would work on the optoelectronic assembly in 2002 in its Helsinki meeting, and agreed at the Singapore meeting In the 2003 several proposals shortly.

The 90 o bend is realized with a radius of curvature that gives a permissible optical loss. (2) Physical Contact: The method to connect optical fibers to realize physical contact of two fibers in a connector by
