Notes:
1. Class 1 Laser Safety per FDA/CDRH, IEC, and EN60825-1 laser safety standards.
2. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average
power.
3. Unfiltered, 20-80%. Complies with FC 1x and 2x eye mask when filtered.
4. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and
∆
DJ.
5. If measured with TJ-free data input signal. In actual application, output TJ will be given by:

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. 5.0 specifications.
Measured with conformance signals defined in IEEE 802.3 specifications.
