Notes:

1.

The data rate can be increased to 12.5Gbps, but the sensitivity will be decreased by approximately 3dB

2.

PR is the average optical power at the fiber face.

3.

PR OMA is the peak to peak optical power at the fiber face (Optical Modulation Amplitude)

where ER is the extinction ratio (linear) of the optical source.

4.

Bandwidth and Low Frequency Cutoff are measured with a small signal sinusoidal light source with –

10dBm average power

5.

Sensitivity is measured with an optical source with an extinction ratio of 3dB.

6.

Stressed receiver sensitivity is measured with 3.5dB vertical eye closure (intersymbol interference) and

with 0.3UI of jitter added. The measurement technique is defined in IEEE 802.3ae.

7.

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.

8.

Value shown is with external power supply filtering.

9.

For best sensitivity, a limiting amplifier may be required for operation.

10. The PD voltage must be connected to a positive 3.3V power supply (nominal).Maximum
