Notes:
1. Parameters are specified over temperature and voltage, at end of life, and for non-rate select option unless otherwise noted.
2. All parameters are measured on a Finisar SFP Evaluation Card unless otherwise noted.
3. For accurate
Δλ20 measurements, an OSA with a resolution band width of ≤ 20pm is recommended.
4. Tolerable back reflection is the max back reflection level at which the power penalty will be <1dB. Power penalty is measured
over fiber (1600ps/nm) at BER = 10-12 with OSNR set at 24dB.
5. Dispersion power penalty is measured in loop back with OSNR set to 30 dB. Data rate and pattern used same as specified for
Optical Input Power. Dispersion power penalty is the difference in Rx power at a BER of 10-12 for 0ps/nm & 1600ps/nm
6. Dispersion noise penalty is measured in loop back with Rx power set between -9dBm and -18dBm. Data rate and pattern used
same as specified for Optical Input Power. Dispersion noise penalty is the difference in OSNR at a BER of 10-12 for 0ps/nm and
1600ps/nm
