1000BASE-SX multimode fiber
1000BASE-LX single-mode fiber
1000BASE-ZX single-mode fiber
Each of the 16 ports in the GM-16X
maximum module throughput of 4 Gigabits to the Alpine backplane. When a GM-16X
an Alpine 3808, and five or more ports of ports 1 through 8 or ports 9 through 16 are simultaneously
forwarding unusually high rates of small, uniformly sized packets (for example, 64 Byte), the
bandwidth through each port can be lower than the expected minimum of 250 Mbps.
When you install and configure a GM-16X
port-based load-sharing (link-aggregation) algorithm when the share has more than four ports because
traffic coming from the GM-16X
the share. Load-sharing using other load balancing algorithms can have up to eight links.
Mini-GBIC Ports
The GM-16X 3 module supports any of the following mini-GBICS:
• SX mini-GBIC
• LX mini-GBIC
• ZX mini-GBIC
NOTE
For more information about the supported mini-GBIC types, see "Mini-GBIC Types" on page 23.
