PRODUCT INFORMATION
1300nm
1A398
High-Performance LED
Test Equipment
The strictly defined 1300 nm wave-
length and high power is ideal for test
equipment applications. It is packaged
in a hermetically sealed can for high
reliability and maximum resistance to
harsh operating environments. The
double-lens optical system results in
optimum coupling of power into the
fiber.
