Notes:
- Average launch power, each lane (min) is informative and not the principal indicator of signal strength. A transmitter with launch power below this value cannot be compliant; however, a value above this does not ensure compliance.
- Even if the TDECQ < 1.4 dB for an extinction ratio of 4.5 dB or TDECQ < 1.3 dB for an extinction ratio of < 4.5 dB, the OMAouter (min) must exceed this value.
- Transmitter reflectance is defined looking into the transmitter
- The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level
- Average receive power, each lane (min) is informative and 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.
- Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with SECQ up to 1.4 dB.
- These test conditions are for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
