APPLICATIONS

  • 10G Ethernet Datacenter Intra-Rack and Inter-Rack links FCBG110SD1Cxx-WX 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 RoHS compliant as described in Application Note AN-20383,4.

  1. Circuit ground is internally isolated from chassis ground.
  2. TFAULT is an open collector/drain output, which is pulled up with a 4.7k – 10k resistor on the

host board, but is grounded inside the SFP+ cable plug.

  1. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.

MOD_ABS pulls line low to indicate module is plugged in.

  1. 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. Figure 1. Diagram of Host Board Connector Block Pin Numbers and Names.
