Gigabit Ethernet Modules
Your Gigabit Ethernet network connects to the
system through a Gigabit Ethernet module. This
single-port module is supported in these
configurations:
■
1000BASE-SX MMF Module
— Can be used with
either 62.5-micron or 50-micron multimode fiber.
See “Cabling the 1000BASE-SX MMF Module”
next for details.
■
1000BASE GBIC Module
— Connects to your
Gigabit Ethernet network using a 1000BASE-LX or
1000BASE-SX Gigabit Interface Converter (GBIC)
transceiver. See “Cabling the 1000BASE GBIC
Module” on page 39 for details.
Your system can support up to four Gigabit Ethernet
modules.
Guidelines for Gigabit Ethernet Cabling
For all Gigabit Ethernet cabling, keep the ports and
connectors free of dust.
Recommended Distances for
1000BASE-SX Ports or Transceivers
When you cable SC connectors to 1000BASE-SX ports
or transceivers, be sure that the length of the
fibercable from the system to any attached device
does not exceed these recommended distances:
■ Use 62.5-micron MMF fiber with a modal
bandwidth specification of 160 MHz*km for
distances of up to 220 m (722 ft).
■ Use 62.5-micron MMF fiber with a modal
bandwidth specification of 200 MHz*km for
distances of up to 275 m (902 ft).
■ Use 50-micron MMF fiber with a modal bandwidth
specification of 400 MHz*km for distances of up
to 500 m (1645 ft).
■ Use 50-micron, 500 Mhz*km modal bandwidth,
MMF fiber for distances of up to 550 m (1805 ft).
Recommended Distances for
1000BASE-LX Transceivers
When cabling SC connectors to 1000BASE-LX
transceivers, be sure that the length of the fiber cable
from the system to any attached device does not
exceed these recommended distances:
■ Use 62.5-micron MMF fiber with a modal
bandwidth specification of 160 MHz*km for
distances of up to 550 m (1805 ft).
■ Use 62.5-micron MMF fiber with a modal
bandwidth specification of 200 MHz*km for
distances of up to 550 m (1805 ft).
■ Use 50-micron MMF fiber with a modal bandwidth
specification of 400 MHz*km for distances of up
to 550 m (1805 ft).
■ Use 50-micron MMF fiber with a modal bandwidth
specification of 500 MHz*km for distances of up
to 550 m (1805 ft).
