Note: All Extreme Networks qualified XENPAK plugables meet or exceed the IEEE 802.3ae 10 Gigabit Ethernet specification. 
The table above shows some XENPAK parameters that may be useful for 10 Gigabit Ethernet deployments.

1

 This information is provided as a reference value and not a pass/fail criteria. The launch power (measured using the 

  average power method used by power meters) is measured at the factory. This data is provided with each module shipped.

2

 62.5 µm (160/200 MHz*km) = 1.6 dB (typically 26 meters)

  62.5 µm (200 MHz*km) = 1.6 dB ) (typically 33 meters)
  50 µm (400 MHz*km) = 1.7 dB ) (typically 66 meters)
  50 µm (500 MHz*km) = 1.8 dB (typically 82 meters)
  50 µm (2000 MHz*km) = 2.6 dB (typically 300 meters)

3

 Depends on type (e.g 62.5 µm or 50 µm ) and modal bandwidth (e.g. 160 Mhz*km, 500 Mhz*km, 2000 Mhz*km, etc.)

4

 5 dBm minimum attenuation required. At 0.3 dB/km, this is approximately 16.7 km

5

 Typical reference values for distance. Optical specifications guaranteed: Tx power>0 dBm, Rx sensitivity < -22 dBm with no  

   path dispersion penalty. Dispersion tolerance up to 1600 ps/nm
