Notes:

1. Input Optical Modulation Amplitude (commonly known as sensitivity) requires a valid 8B/10B encoded input.

2. An OMA of 61

PW is approximately equal to an average power of –14 dBm, avg with an Extinction Ratio of 9 dB.

3. An OMA of 49

PW is approximately equal to an average power of –15 dBm, avg with an Extinction Ratio of 9 dB.

4. 8.5 Gb/s stressed receiver vertical eye closure penalty (ISI) min. is 3.45 dB for 50

Pm fiber and 3.52 dB for 62.5 Pm fiber.

5. 4.25 Gb/s stressed receiver vertical eye closure penalty (ISI) min. is 1.67 dB for 50

Pm fiber and 2.14 dB for 62.5 Pm fiber.

6. 2.125 Gb/s stressed receiver vertical eye closure penalty (ISI) min. is 1.26 dB for 50

Pm fiber and 2.03 dB for 62.5 Pm fiber.

7. These average power values are specified with an Extinction Ratio of 6 dB. The loss of signal circuitry responds to valid 8B/10B encoded peak to

peak input optical power, not average power.
