Notes:

  • Circuit ground is internally isolated from chassis ground.
  • Laser output disabled on TX Disable >2.0V or open, enabled on TX Disable<0.8V.
  • Should be pulled up with 4.7k - 10kohms on host board to a voltage between 2.0V and 3.6V.

MOD_DEF(0) pulls line low to indicate module is plugged in.

  • LOS is LVTTL output. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

Notes:

  • Gigabit Ethernet and 1x Fibre Channel compliant.  
  • Tested with a PRBS 27-1 data pattern.
  • Dispersion limited per FC-PI-2 Rev. 10.
  • Attenuation of 0.55 dB/km is used for the link length calculations. Please refer to the Optical Specifications in

Table IV to calculate a more accurate link budget based on specific conditions in your application.
