OET-1000
Downloadable Data Sheet
From special quality of storehouse element as equipment that OET-1000 offers a basis experiment about ticklish optical communication in general subject about optical communication education optical fiber connection characteristic and transmission characteristic.
And designed so that can do a fundamental optical communication experiment that use signal conversion circuit and surrounding circuit.
The biggest advantage can to be more easy about communication method to use mineral ore because do so that can confirm state that do total reflection in optical fiber as well as can confirm cast which is displayed from actuality source of light because Laser Diode that is used to source of light used wave length of thorn area (650nm) on eye directly and approach interestingly more in this equipment.
Also, was composed so that can do optical communication trial run and infrared rays communication that use indirectness variation way using together option module from outside.
Because elect themes are composed from basis theory to an actuality experiment systematically, to educators established theory so that can master done technology be.
OET-1000 is education equipment that do interested persons or general college and in optical communication connection industry spot business truth department which make almsgiving can cultivate general knowledge about optical communication to persons in optical communication field.
