Using Optical Splitters with 10GBE Links
• Supported Configurations, page A-1
• Unsupported Configuration, page A-2
When designing a deployment with the SCE8000, it is important to keep in mind certain characteristics
of the 10GBE link that affect the configuration of optical splitters and SPAN ports.
• Ten Gigabit Ethernet does not support autonegotiation (unlike regular GBE). The fixed 10GBE
configuration is as follows:
– duplex = full
– speed = 10 GBE
• The 10GBE port is UP once it detects light (and correct sync pattern) in the RX input.
• A Switch or Router port will not transmit data unless it is UP (that is, it detects a good signal on the
RX input).
Supported Configurations
Due to the 10GBE characterstics described above, the following configurations are supported in the 10
GBE environment.
