Electro-Optical Characteristics
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
= reverse voltage.
