Notes:
1. Circuit ground is internally isolated from chassis ground.
2. T
FAULT
is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on
the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high
output indicates a transmitter fault caused by either the TX bias current or the TX output power
exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the
output is pulled to <0.8V.
3. Laser output disabled on T
DIS
>2.0V or open, enabled on T
DIS
<0.8V.
4. Should be pulled up with 4.7k - 10 kohms on host board to a voltage between 2.0V and 3.6V.
MOD_DEF(0) pulls line low to indicate module is plugged in.
5. Finisar FTLF1318xxxxx transceivers operate at 1x Fibre Channel and Gigabit Ethernet data rates and
respective protocols without active control.
6. LOS is open collector output. Should be pulled up with 4.7k – 10 kohms on host board to a voltage
between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

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

Notes:
1. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
2. Also specified to meet curves in FC-PI-2 Rev. 10.0 Figure 18, which allow trade-off between
wavelength, spectral width and OMA.
3. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average
power.
4. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E) and FC 1x eye masks when filtered.
5. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and
Δ
DJ.
6. Measured with conformance signals defined in FC-PI-2 Rev. 10.0 specifications.
