Parameters
[1] 50 Ω measurement system, f = dc - 3GHz
[2] Submount temperature between 20˚C to 35˚C start of life to achieve required λp. For the 10mW version,
submount temperature is between 15˚C to 35˚C start of life.
[3] Standard product dispersion penalty will be compliant to the specified link length of 360km using an
extinction ratio of 10dB. Fiber dispersion characteristics are derived from the following equation.
Where So = 0.092ps/(nm
[4] Measurements determined from 20 - 80% pk - pk.
[5] For more information on wavelength control and drift over life refer to applications note DR1670. To give
symmetrical wavelength performance about the ITU channel wavelength (+/-95pm) offset the laser
wavelength by –50pm at start of life set up.
