Cabling
• Twisted-pair segments can be Unshielded Twisted Pair (UTP) or
Shielded Twisted Pair (STP) cabling. The cable must comply with the
IEEE 802.3 10/100/1000Base-T standard for Categor y 5e/6. The
cable between the conver ter and the link par tner (switch, hub,
workstation, etc.) must be 100 meters (328 ft.) or less in length.
• Fiber segments using Single Mode connectors must use 9/125µm
Single Mode fiber cable. The maximum link distance in full duplex
operation is 10 Kilometers (6.2 miles). The maximum link distance
in half duplex operation is 412 meters (1352 ft).
• The maximum distance of fiber segments using Multi-Mode
connectors measures 550 meters (1804 ft.) with 50/125µm or
62.5/125µm Multi-Mode fiber cable.
Network Connection
A. Select the appropriate length Categor y 5e or 6 twisted pair cable.
Connect one end of the twisted pair cable to the RJ-45 connector
on the conver ter and the other end of twisted pair cable to the RJ-
45 connector on any 10/100/1000Base-T device.
B. Connect one end of a fiber jumper to the SC connector on this
conver ter and the other end of the fiber jumper to the SC
connector on the other 1000Base-SX/LX device.
C. Attach the power adapter DC jack to the conver ter. Verify that the
Power LED is on.
D. Verify that the UTP “LK/ACT” LEDs light when cable connection is
installed correctly. Verify that Fiber “LK/ACT” LED blinks to indicate
network activity.
Troubleshooting
• Verify that you are using the right power adapter, DC 5V, 2A
(minimum). Using a power adapter with DC output greater than 5V
could result in damage to the unit and/or personal injur y.
• Confirm the proper UTP/Fiber cable is being used. The Single Mode
conver ter must use Single Mode fiber optic cable.
