• Supports 10.3125 Gb/s bit rate
• RoHS-6 compliant (lead-free)
• Available in lengths up to 20m
• SFI Limiting interface
• Single 3.3V power supply
• Low power dissipation
• Commercial temperature range:
0°C to 70°C
• Rigid pull-tab for improved high-

APPLICATIONS
• 10G Ethernet Data Center Intra-Rack
and Inter-Rack links
Finisar’s FCBG110SD1Cxx 10Gb/s SFPwire® SFP+ active optical cables are designed
for use in 10-Gigabit Ethernet links. They are electrically compliant with SFF-84311, and
the mechanical SFP+ plug is compatible with SFF-84322. SFPwire is SFI limiting. No
host electrical transmitter pre-emphasis is required. No host electrical receiver linear
equalization is required. Host board designers using an EDC PHY IC should follow the
IC manufacturer’s recommended settings for interoperating the host-board EDC PHY
with a limiting receiver. SFPwire is compliant per the RoHS Directive 2011/65/EU. See
Finisar Application Note AN-2038 for more details.

Notes:
1. Circuit ground is internally isolated from chassis gr ound.
2. TFAULT is an open collector/drain output, which is pulled up with a 4.7kΩ – 10kΩ resistor on the host
board, but is grounded inside the SFP+ cable plug.
3. Laser output disabled on TDIS >2.0V or open , enabled on TDIS <0.8V.
4. Shoul d be pulled up with 4 .7 kΩ – 10kΩ on host board to a voltage between 2.0V and 3.6V.
MOD_ABS pulls line low to indicate module is plugged in.
5. LOS is open collector output. Should be pulled up with 4.7kΩ – 10kΩ on host board to a voltage
between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
