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 = 10-10

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 = 10-10
