Finisar FTLX3671MTCxx transceivers are Enhanced Small Form Factor Pluggable
SFP+ transceivers designed for use in DWDM links up to 40km of G.652 single mode
fiber, for multi-rate applications from 1.2 through 11.3 Gb/s, carrying 1-10G Ethernet, 1-
10G Fibre Channel, 10G OTN traffic or CPRI options 2 through 8 traffic. The
FTLX3671MTCxx transceivers are compliant with SFF-8431
1
and SFF-8432

.
Finisar FTLX3671MTCxx transceivers use internal re-timers (clock and data recovery
or CDR) for the transmitter and the receiver to guarantees compliance with the
SONET/SDH jitter requirements.
Digital diagnostics functions are available via a 2-wire serial interface, as specified in
SFF-8472

Notes:
1. Circuit ground is internally isolated from chassis ground.
2. 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.
3. 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.
4. Laser output disabled on T
DIS
>2.0V or open, enabled on T
DIS
<0.8V.
5. Internally pulled down per SFF-8431 Rev 4.1.
6. 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.

20 – 80%. Measured with Module Compliance Test Board and OMA test pattern. Use of four 1’s and four 0’s
sequence in the PRBS 9 is an acceptable alternative. SFF-8431 Rev 4.1. Lower limit as per XFP MSA, Tab. 18 (as
the SFP+ MSA does not define electrical specifications for transceivers with internal retrimers or CDRs).
3. LOS is an open collector output. Should be pulled up with 4.7k – 10k on the host board. Normal operation is
logic 0; loss of signal is logic 1.
4. See Section 2.8.3 of SFF-8431 Rev 4.1.
5. Power consumption measured at 85C case temperature, beginning of life and 3.3V supply voltage.
6. Contact Finisar if a lower power consumption variant is required.
7. With both receiver and transmitter CDR OFF.
