Optical and Electrical Characteristics
(25 C Case Temperature)
Note 1: Measured at the exit of 100 meters of fiber.
Note 2: Mounted in a heatsinked metal housing.
This is the ultimate in high power for
850 nm LEDs - making it the device
of choice for high power transmis-
sion via large core fibers. The her-
metically sealed package contributes
to its high reliability and the device
can withstand the harshest environ-
mental conditions.
