FTLF1428P2BNV Preliminary Product Specification – July 2008
Finisar
Notes:
1. Non-condensing.
2. Module power consumption never exceeds 1W.
3. AC coupled.
4. Or open circuit.
5. Into 100 ohm differential termination.
6. 20 – 80 %.
7. LOS is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
8. 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)
6
, September 14, 2000.
The Power Supply Rejection applies for a supply voltage range of 3.1 to 3.6 V.
9. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and
Δ
DJ.
10. For 8.5 Gb/s operation, Jitter values for gamma T and gamma R are controlled by TDP and stressed
receiver sensitivity.

Notes:
1. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
2. High Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
3. Low Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
4. Also specified to meet curves in FC-PI-4 Rev 7.00

Figures 21, 22, and 23, which allow trade-off
between wavelength, spectral width and OMA.
5. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average
power.
6. For 8.5 Gb/s operation, Jitter values for gamma T and gamma R are controlled by TDP and stressed
receiver sensitivity.
7. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye masks when filtered.
8. Measured with conformance signals defined in FC-PI-4 Rev. 10.0 specifications. Value in OMA.
