4. 20 – 80 %.
5. Signal detect is LVTTL. Logic 1 indicates normal operation; logic 0 indicates no signal detected.
6. All transceiver specifications are compliant with a power supply sinusoidal modulation of 20 Hz to 1.5
MHz up to specified value applied through the power supply filtering network shown on page 23 of the
Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA), September 14, 2000
