4. As a connection is made, check the Link LED on the module to be sure that the

connection is valid.

The 10GBASE-LR fiber optic ports operate at 10 Gbps full duplex. The maximum

length for fiber optic cable operating at 10 Gigabit speed is 10 km (6.2 miles.)

Connectivity Rules

When adding hubs (repeaters) to your network, please follow the connectivity rules

listed in the manuals for these products. However, note that because switches break

up the path for connected devices into separate collision domains, you should not

include the switch or connected cabling in your calculations for cascade length

involving other devices.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also

work for 1000BASE-T, providing that all four wire pairs are connected. However, it is

recommended that for all critical connections, or any new cable installations,

Category 5e (enhanced Category 5) or Category 6 cable should be used. The

Category 5e specification includes test parameters that are only recommendations

for Category 5. Therefore, the first step in preparing existing Category 5 cabling for

running 1000BASE-T is a simple test of the cable installation to be sure that it

complies with the IEEE 802.3-2002 standards.
