Notes:
1.
Into single mode fiber, 9/125
m diameter.
2.
Equivalent extinction ratio specification for Fiber Channel. Allows smaller ER at higher average power.
3.
Measured at nominal data rate. These are unfiltered 20%~80% values.
4.
The sensitivity is tested at BER of 1×10
-12 or better with an input signal consisting of 27-1 NRZ PRBS.
