Notes:
7. The Output Optical Power is measured with the following conditions:
• 1 meter of fiber with cladding modes removed.
• The input electrical signal is a 12.5 MHz square wave.
• The Beginning of Life (BOL) to End of Life (EOL) degradation is less than 0.5 dB.
8. The relationship between FWHM and RMS values for spectral width can be derived from the assumption of a Gaussian-shaped spectrum
which results in RMS = FWHM/2.35.
9. These are 10-90% values.
