Fiber-Optic Board Cabling
The fiber-optic Gigabit Ethernet board is connected to the network using fiber-optic
cable. The cable, which is not included in the shipment, must be a 50-micron or
62.5-micron multimode duplex cable with an LC connector.
Table 1-1 lists SGI fiber-optic cables.
Table 1-2 lists operating ranges for 50-micron and 62.5-micron cables for a 1000-BASE-SX
port. Fiber type is MM.
This card only supports 1000-Base-SX.
