TWISTED-PAIR CABLE SPECIFICATIONS
The physical characteristics of 10BASE-T cable must meet or exceed IEEE 802.3
10BASE-T specifications. Though 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 a later upgrade to 100BASE-TX. DO NOT USE FLAT OR
SILVER SATIN WIRE.
The physical characteristics of 100BASE-TX cable must meet or exceed IEEE 802.3
100BASE-TX specifications. Category 5 cable or better is required. Either shielded
twisted pair (STP) or unshielded twisted pair (UTP) can be used. DO NOT USE
FLAT OR SILVER SATIN WIRE.

RATE CONVERSION
The two-port Ethernet/Fast Ethernet bridging media converter can
provide rate conversion between terminal devices on the 10BASE-
T copper legacy Ethernet network and terminal devices on the
100BASE-SX fiber Fast Ethernet network.
DISTANCE EXTENSION
The two-port Ethernet/Fast Ethernet bridging media converter can
extend half-duplex network distances by dividing CSMA/CD
collision domains.
The two-port Ethernet/Fast Ethernet bridging media converter also
can enable connection of twisted pair to fiber cabling in a full-
duplex Fast Ethernet environment.
CONGESTION REDUCTION
The two-port Ethernet/Fast Ethernet bridging media
converter can reduce congestion by segmenting
network traffic.
The bridging media converter does not forward
collision signals or error packets from one
CSMA/CD collision domain to another, improving
baseline network performance.
And the bridging media converter filters packets
destined for local devices, also reducing network
congestion.
