Class 1 Laser Safety per FDA/CDRH, and EN (IEC) 60825 laser safety standards.
Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average
power.
Unfiltered, 20-80%. Complies with FC 1x and 2x eye mask when filtered.
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 OUT = DJ IN + Δ DJ +
( TJ IN ? DJ IN ) 2 + ( Δ TJ ? Δ DJ ) 2

Applicable for Rate Selectable version only in low bandwidth mode.
Specifications are for 50 micro-meter or 62.5 micro-meter fiber.
As measured with 9dB extinction ratio.
Measured with conformance signals defined in FC-PI-2 Rev. 7.0 specifications.
