[8023-POEP] Midspan TF for WG - UPDATE



Please find update in the compliance tests part.

 

---

When an Alternative A Midspan is connected to a 100BASE-TX PHY, the Midspan transfer function gain  shall be  higher then  from 100KHz to 1MHz at the pins of the PI used as 100BASE-TX transmit pins with the additional requirement that the requirements will be met with a DC bias current between 0 mA and TBD mA.

Compliance test shall be performed by applying test signal to the Midspan signal input through 100W±1% source impedance.  The Midspan signal output will be connected to 0.5m ±10% CAT5 cable, terminated with 100W±1%.

The transfer function will be measured from the output termination to the test signal source.
