Finisars FTLX2072D327/FTLX2072D333 10Gb/s Enhanced Small Form Factor Pluggable
SFP+ transceivers are designed for use in 10-Gigabit Ethernet links up to 10km over a
single-strand Single Mode fiber. This capability doubles the capacity of installed legacy
1
single mode fiber links. They are compliant with SFF-8431 and IEEE 802.3ae 10GBASE-
3 4
LR/LW , and 10G Fibre Channel 1200-SM-LL-L . Digital diagnostics functions are
5
available via a 2-wire serial interface, as specified in SFF-8472 . The
FTLX2072D327/FTLX2072D333 is a limiting module, i.e., it employs a limiting
receiver. Host board designers using an EDC PHY IC should follow the IC manufacturers
recommended settings for interoperating the host-board EDC PHY with a limiting receiver
6
SFP+ module. The optical transceiver is compliant per the RoHS Directive 2011/65/EU .

Notes:
1. Circuit ground is internally isolated from chassis ground.
2. T is an open collector/drain output, which should be pulled up with a 4.7k 10k Ohms resistor on
FAULT
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 >2.0V or open, enabled on T <0.8V.
DIS DIS
4. Internally pulled down per SFF-8431 Rev 4.1.
5. LOS is open collector output. Should be pulled up with 4.7k 10k on host board to a voltage
between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
