1. BOL value; EOL = 80 mA.

2. The slope efficiency is used to calculate the modulation current for a desired output power. This modulation current plus the threshold current

comprise the total operating current for the device.

3 1510 nm wavelength also available.

4. Corrected for electrical pulse fall time.

5. V

R
