Does anyone know the history behind the connector return loss numbers
proposed for 10 GbE?

The return loss for multimode connections shall be greater than 20 dB.
The return loss for single mode connections shall be greater than 26 dB.

Do the transceivers integrate isolators into them to address return loss?

Has any testing be done to demonstrate compatibility?

Thanks
