Operating Instructions
In order to achieve an operating lifetime > 10

h, which is required for Telcom applications, a
forward current of
I
F
= 50 mA DC is recommended.
Notes:
1) Driving current is a square wave, 50 % duty cycle, 60 mA
pk
current at 1 MHz.
e
is the average optical power coupled into the specified fiber.
2) Optimum coupling on cap surface, no adjustment in z-axis necessary.
