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 = 10-10
Note 4: OSNR penalty is measured in loop back. Data rate and pattern used same as specified for Optical Input
Power. OSNR penalty is measured at BER = 10-10
