CC
Into single mode fiber, 9/125µm diameter.
Equivalent extinction ratio specification for Fiber Channel. Allows smaller ER at higher average power.
Measured at nominal data rate. These are unfiltered 20%~80% values.
The sensitivity is tested at BER of 1×10
=3.135V to 3.465V, Data Rate=4.25Gb/sec, PRBS=2
