    2. AC coupled.

    3. Or open circuit.

    4. Into 100 ohm differential termination.

    5. 20 – 80 %

    6. LOS is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.

    7. 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.

    8. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ and DDJ.
