HAPTER ABLING
Use 9-micron SMF fiber for distances of up to 10
kilometers (6.2 miles). The specification requires
and specifies 5 kilometers (3.1 miles).
Use a conditioned launch cable to connect the
1000BASE-LX transceiver to multimode fiber. Using
this cable ensures reliability over the maximum 550 m
distance.

Cabling the 1000BASE-SX MMF Module

The 1000BASE-SX MMF module provides one Gigabit
Ethernet port that uses multimode fiber with an SC
connector.
To cable the 1000BASE-SX module:
Read and follow the "Fiber and Laser Safety
1
Precautions" on page 35 for safe operation.
Plug the male SC connector on the fiber cable into
2
the port on the Gigabit Ethernet module until it clicks
into place. See Figure 15.
Attach the other end of the fiber cable to the
3
network device that you want to connect.
Repeat steps 1 through 3 for additional Gigabit
4
Ethernet modules.
