N F-905 series are of red lighting source upon 650 nm conductor
for laser enitter, drived by constant current source to emit regular
red light. Connecting the int erface i n multi-mode or singal mode
starts up fiber malfunction testing.
It is a indispensible tool in respects of fiber engineering,
maintaining,producing and studying of light components .
