APPLICATIONS
DWDM 80km links for:
Fibre Channel 8.5G and 10G
10G Ethernet
10Gb/s SONET/SDH/OTN
ITU-T G.698.1 DS100S1-2Dz(C)
Finisar’s FTLX3871MCCxx transceivers are Enhanced Small Form Factor Pluggable
SFP+ transceivers designed for use in 10-Gigabit multi-rate links up to 80km of G.652
single mode fiber. They are compliant with SFF-8431
1
, SFF-8432
2
and G.698.1
DS100S1-2Dz(C), and support SONET OC-192, SDH STM-64, 10G Ethernet ZR and
10G Fibre Channel over 80km fiber. Finisar’s FTLX3871MCCxx transceivers use
internal retimers (clock and data recovery or CDR) IC’s for both the transmitter and the
receiver. This guarantees compliance with the SONET/SDH jitter requirements, and they
can be used to set the electrical interface XFI-compliant.
Digital diagnostics functions are available via a 2-wire serial interface, as specified in
SFF-8472
3
. The optical transceiver is compliant per the RoHS Directive
2011/65/EU
4
. See Finisar Application Note AN-2038 for more details

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.

Internally pulled down per SFF-8431 Rev 4.1. See Sec. X of this datasheet for the logic table to use for
the internal CDRs locking modes.
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.
