Connect the Twisted-Pair Copper Cable
Ensure that the correct cable type is installed to support the highest speed and mode of operation to be
selected.
Although Category 3 cable is adequate for the 10Base-T installation, Category 5 cable is strongly
recommended, since Category 3 cable can not be used for 100Base-TX installation.
10Base-T / Ethernet Collision Domain
•
If half-duplex cable is used, refer to the 5-Segment Rule before installing the 10Base-T twisted-
pair copper cable.
•
If full-duplex cable is used, the 5-Segment Rule does not apply. The cable lengths are
constrained by the cable requirements.
100Base-TX / Fast Ethernet Collision Domain
•
If half-duplex cable is used, refer to the 512-Bit Rule before installing the 100Base-TX twisted-
pair copper cable.
•
If full-duplex cable is used, the 512-Bit Rule does not apply. The cable lengths are constrained by
the cable requirements.
Note: A Fast Ethernet collision domain can have one class 1 repeater or two class 2 repeaters.
Install the Twisted-Pair Copper Cable
Note: The AutoCross feature allows either MDI (straight-through) or MDI-X (crossover) cable
connections to be configured automatically, according to the network conditions.
1.
Locate or build IEEE 803.2 compliant 10Base-T or 100Base-TX cable, with RJ-45 connectors
installed at both ends.
2.
Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the SBFTF10xx-10x
media converter.
3.
Connect the RJ-45 connector at the other end of the cable to the RJ-45 port on the other device
(switch, workstation, etc.).
