Finisar’s FTLF1419P1xCL Small Form Factor Pluggable (SFP) transceivers are
compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA)
1
.
They simultaneously comply with Gigabit Ethernet as specified in IEEE Std 802.3
2
, and
1x and 2x Fibre Channel as defined in FC-PI 13.0
3,4
. The optical transceivers are
compliant per the RoHS Directive 2011/65/EU. See Finisar Application Note AN-2038
for more details. Digital diagnostics functions are available via the 2-wire serial bus
specified in the SFP MSA.

Notes:
1. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
2. Meets curves in FC-PI 13.0 Figures 18 and 19, 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 FC 1x and 2x eye mask when filtered.
5. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and
∆
DJ.
6. Measured with conformance signals defined in FC-PI 13.0 specifications.
7. As measured with 9dB extinction ratio. Measured with a PRBS 2
