Recently I found out that the above displayed part of the specs did NOT mean Melco uses some form of opto isolation (galvanically isolating the ethernet inputs by converting the input signal into light). Instead it means that they 'lead' the light from ethernet status/activity LED's (which are not inside the ethernet connector but on the PCB surrounding it) through a plastic "pipe" to the back of the device.
For their "complete electrical isolation" they still use 'conventional' pulse transformers.

IMO it's specs are bordering on deceiving...perhaps crossing the border but I'm not sure I'm not a lawyer.
