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 power 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 power 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
5. Tolerable back reflection is the max back reflection level at which the power penalty will be <1dB. Power
penalty is measured over fiber (2400ps/nm) at BER = 10-10 under high OSNR (>28dB) conditions.
