For 10.57 Gbps, the sensitivity is degraded by approximately 1dB. NOTES 1. The data rate can be increased to 10.7Gbps for Fibre Channel applications with minimal degradation in performance. 7. Stressed receiver sensitivity is measured per ANSI X3.T11 FC-PI-4 (8Gbps Fibre Channel) requirements. 2. PR is the average optical power at the fiber face. 8. 3. PR,OMA is the peak to peak optical power at the fiber face (Optical Modulation Amplitude) Measured with 231 PRBS at 10.3 Gbps. Rise/Fall times are corrected for optical source Rise/Fall times. The corrected value is calculated as the square root of the difference of the squares of the measured differential detector output and the source 9. Value shown is with external power supply filtering. PR ,OMA 2 PR (ER - 1) ER + 1 where ER is the extinction ratio (linear) of the optical source. 4. The TIA incorporates automatic gain control, which maintains approximately 300mV differential electrical output over the entire operating range. Refer to the chart below for typical differential transimpedance as a function of both average optical power and optical modulation amplitude. 5. Bandwidth and Low Frequency Cutoff are measured with a small signal sinusoidal light source with -8dBm average power. 6. Sensitivity is measured with an optical source with an 10. For best sensitivity, a CDR that incorporates EDC may be required. 11. With an ANSI X3.T11 FC-PI-4 specified input stressed eye (see note 8) 12. Harmonic distortion is defined as the ratio of power in all harmonic frequencies divided by the power in the fundamental frequency 13. The electrical performance of the ROSA is dependent upon the quality of the electrical connection between the TO can and the circuit board. AOC cannot guarantee all performance specifications for parts without the flex circuit attached.
