About Unidirectional Ethernet
You can set stubless Gigabit Ethernet ports to unidirectionally transmit or receive traffic. Unidirectional
Ethernet uses only one strand of fiber for either transmitting or receiving one-way traffic for the Gigabit
Ethernet Port, instead of two strands of fiber for a full-duplex Gigabit Ethernet Port. Configuring your
Gigabit Ethernet Port 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 streams.
