SINGLE MODE






            So narrow that light can travel through it only in a

              single path.

            All the light to travel in only one mode.


            Is a single stand of glass fiber with a core of 8 to 10

              microns in diameter.

            Used for long distance more than 5 kilometers in

              length. (50 times more distance than multimode).




            higher transmission rate.

            provides much better performance with lower

              attenuation.


            is extremely expensive and very difficult to work

              with.
