Notes:

1. RMS spectral width is the standard deviation of the spectrum

2. If measured into type A1a.2 or type A1a.3, or A1a.4, 50 um fiber, in accordance with IEC 61280-1-4.

3. The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level on one lane. The receiver does not have to operate correctly at this input power.

4. Average receive power, each lane (min) is not the principal indicator of signal strength. A received power below this value cannot be compliant; however, a value above this does not ensure compliance.

5. For when Pre-FEC BER is 2.4 x 10-4.

6. Measured with conformance test signal at TP3 (see 167.8.14) for the BER specified in 167.1.1.

7. These test conditions are for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
