The growth of bandwidth requirement
promoted international optical communication development and fiber optics has
become the most important transmission medium for communication area.
As requirement of fiber-to-the-home service
growing fast in Europe, USA ,
and Japan
and the market of fiber optics commutation is not developed completely, still with
great potential. This also push the development of fiber optics components.
Categories of fiber optics products are
optical fiber, cable, optics active component, optics passive component and
transmission device, and it request strictly and cost highly.
Main categories of optics passive component
are fiber optical connector, coupler, isolator, attenuator, optical add-drop
mux, optics switch, etc. The largest
percent of these optics passive components is optical fiber connector, and then
the second is optics coupler and isolator.
