Using optical fiber ethernet in colibri (i.e. imx6)

We would like to use our imx6 with optical ethernet cables. It’s not yet clear to me whether we can just replace the magnetics with an optical transceiver such as the broadcom AFBR-5823TQZ or if the TX/RX signal levels are incompatible (AFBR-5823TQZ is LVPECL but I’m unsure of the standard which the colibri’s use to drive the default magnetics).

Thanks,
Summer

Colibri iMX6 uses the Microchip/Micrel KSZ8041NL Ethernet PHY. And its RX ant TX pins are routed directly to SOM X1 connector. You can find details about that PHY here.
