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