OP4520-2 Fiber Optic Configuration
A: Fiber optic connector module, providing 6RX and 6 TX channels. The RX transceivers are Avago AFBR-2624Z and the TX transceivers are Avago AFBR-1624Z. These channels can be used as digital I/Os or for low-speed communication protocols. The ORION protocol, developed by OPAL-RT, is compatible with these channels and available in custom bitstreams.
