DOCUMENTATION (Tld=Tset)

• Fiber output power vs. Laser forward current at Tld=Tset and Tc=-20,25,70°C

• BER curves at 2.48832Gb/s modulation

• Threshold current (Ith)

• Laser forward current (Iop) at Pf=2mW

• Laser forward voltage (Vop) at Pf=2mW

• Laser operating temperature (Tset) at λc (Note 5)

• Monitor current (Imon) at Pf=2mW

• Thermistor resistance (Rth)

• Cooler current (Ipe) at Pf=2mW and Tc=70°C

• Cooler voltage (Vpe) at Pf=2mW and Tc=70°C

Note 5) Tset is attached as a reference data. Rth should be used in order to tune the wavelength to the specified

value accurately.
