Notes:
1. Parameters are specified over temperature and voltage, at end of life unless otherwise noted.
2. All parameters are measured on a Finisar SFP Evaluation Card unless otherwise noted.
3. Dispersion penalty is measured in loop back with OSNR set at Rx < 28 dB. Data rate and pattern used same
as specified for Optical Input Power. Dispersion penalty is measured at BER = 10
