You can set non-blocking GigaPorts to unidirectionally transmit or receive traffic. Unidirectional

Ethernet uses only one strand of fiber for either transmitting or receiving one-way traffic for the

GigaPort, instead of two strands of fiber for a full-duplex GigaPort Ethernet. Configuring your GigaPorts

either to transmit or receive traffic effectively doubles the amount of traffic capabilities for applications,

such as video streaming, where most traffic is sent as unacknowledged unidirectional video broadcast

Configuring Unidirectional Ethernet

You must configure Unidirectional Ethernet on the non-blocking GigaPort, which will automatically

disable UDLD on the port.
