Notes :
1.
DC coupled internally. See Figure 2 of Laserwire (P/N FCBP110LD1Lxx) datasheet for input eye mask
requirements. Self biasing 100 Ohm differential input. Must be AC coupled on HOST
2.
DC Coupled with 100 Ω differential output impedance. Must be AC coupled on HOST.
Laserwire (P/N FCBP110LD1Lxx) datasheet for output eye mask.
See Figure 3 of

IV.
All transceiver specifications are guaranteed with the given power supply sinusoidal modulation up to specified
amplitude over a range of 20 Hz to 1.5 MHz applied through the power supply filtering network shown in
Figure 12. See SFF-8431 Rev 2.0 1 (SFP+) specification section D.16.3 Power Supply Tolerance Testing for the
test methodology but with the module replaced by a 15 ? load for amplitude calibration.
