Note 1:
Parameters are specified over temperature and voltage, at end of life unless otherwise noted.
Note 2:
All parameters are measured on a Finisar GBIC Evaluation Card unless otherwise noted.
Note 3:
Dispersion penalty is measured in loop back. Data rate and pattern used same as specified for Optical
Input Power. Dispersion penalty is measured at BER = 10
