Class 1 Laser Safety per FDA/CDRH, (IEC) and EN 60825-1 laser safety regulations.
Equivalent extinction ratio specifi cation for Fibre Channel. Allows smaller ER at higher average power.
Unfi ltered, 20-80%. Complies with FC 1G and 2G eye mask when fi ltered.
Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ and Δ DJ.
If measured with TJ-free data input signal. In actual application, output TJ will be given by
TJ
Specifi cations are for 50 micrometer or 62.5 micrometer fi ber.
As measured with 9 dB extinction ratio.
