TRANSITION Networks C/E-PSW-SX-01 series two-port bridging media
converter, designed to be installed in the TRANSITION Networks Media
Conversion Center, E-MCC-1600, segments 10BASE-T/100BASE-TX copper
and 100BASE-SX fiber Ethernet™ collision domains to extend total network
diameter, to reduce network congestion, and to convert between legacy
10BASE-T and 100BASE-SX environments.
A four-position DIP switch located at the side of the media converter allows siteselection of auto-negotiation, of 10MB/s or 100Mb/s speed, and of full-duplex or
half-duplex mode.
C/E-PSW-SX-01
Provides an RJ-45 twisted-pair
connector to UTP/STP copper cable
and a set of RX (receive) and TX
(transmit) ST 850nm multimode
fiber connectors.
C/E-PSW-SX-01(SC)
Provides an RJ-45 twisted-pair
connector to UTP/STP copper
cable and an RX (receive) and TX

THE C/E-PSW-SX-01 IN THE NETWORK ETHERNET CABLE SPECIFICATIONS
FIBER CABLE SPECIFICATIONS
The physical characteristics of the 100BASE-SX cable must meet or exceed the
100BASE-SX specifications.
MULTIMODE
Fiber-optic Cable Recommended: 62.5 / 125 µm multimode fiber
Optional: 50 / 125 µm multimode fiber
Modal bandwidth: ≤160MHz-Km
Fiber-optic Transmitter Power: min: -20 dBm max: -12 dBm
Fiber-optic Receiver Sensitivity: min: -24 dBm max: -12 dBm
Wavelength: 850nM
Bit error rate: ≤2.5
-10
Maximum Cable Distance: 300 meters
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.
Category 3:
Gauge 24 to 22 AWG
Attenuation 6.5 dB/100’ @ 10 MHz
Differential Characteristic Impedance 100 Ω ±15%
Category 5:
Gauge 24 to 22 AWG
Attenuation 22 dB/100’ @ 100 MHz
Differential Characteristic Impedance 100 Ω ±15%
Maximum Cable Distance: 100 meters (330 feet)

RATE CONVERSION
The two-port Ethernet/Fast Ethernet bridging media converter can
provide rate conversion between terminal devices on the 10BASET 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 fullduplex 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.
