CABLE SPECIFICATIONS
Twisted Pair Copper Cable and Connectors
CABLE Category 3 wire or better is required; category 5 wire is recommended. Either
shielded twisted pair (STP) or unshielded twisted pair (UTP) can be used. DO NOT
USE FLAT OR SILVER SATIN WIRE.
Gauge 24 to 22 AWG
Differential Characteristic Impedance 100
Ω
±10% @ 10 MHz
Category 3 Attenuation 28 dB/1000’ @ 10 MHz
Category 5Attenuation 20 dB/1000’ @ 10 MHz
NOTE: The active pair in a twisted-pair copper 5250-compliant network are pins 4 &
5, pins 3 & 6, or pins 1 &2, straight-through configuration. Use dedicated wire pairs
(such as blue/white & white/blue, orange/white & white/orange) for the active pins.
Minimum cable distance MUST be 25 feet.
Typical Maximum Cable Distance:
1X Category 3/Host to PSM-8E Up to 2000 feet
1X Category 3 /PSM-8E to Device Up to 1800 feet
2X Category 3 /Host to PSM-8E Up to 1000 feet
2X Category 3 /PSM-8E to Device Up to 900 feet
1X Category 5 /Host to PSM-8E Up to 2000 feet
1X Category 5 /PSM-8E to Device Up to 2200 feet
2X Category 5 /Host to PSM-8E Up to 1500 feet
2X Category 5 /PSM-8E to Device Up to 1650 feet
Derate cable distances as follows:
1X Category 3
Up to 62 feet
2X Category 3 Up to 38 feet
1X Category 5 Up to 16 feet
2X Category 5 Up to 11 feet
NOTE: Cable distances over 1000 feet must b e derated by 25% for ring
applications.
CONNECTORS Shielded RJ-45 or DB-25
Fiber Cable and Connectors
CABLE
Fiber Optic Cable Recommended: 62.5 / 125 µm multimode fiber
Optional: 100 / 140 µm multimode fiber
85 / 125 µm multimode fiber
50 / 125 µm multimode fiber
Peak Power Wavelength: 820 nanometers
Typical Maximum Cable Distance:
Point-to-point Up to 2 kilometers
Ring (3 units) Up to 1.5 kilometers between units and
4.5 kilometers overall
Ring (4 units) Up to 1 kilometers between units and
4 kilometers overall
Fiber-optic Link Budget:
Point-to-point 12 dB (typical)
Ring (3 units) 10 dB (typical)
Ring (4 units) 8 dB (typical)
CONNECTORS ST
Multiplexed signals are carried over fiber from the host PSM-8E multiplexer
to one or more device PSM-8E multiplexer(s).
NOTE: If more than one device PSM-8E multiplexer is connected to the host
PSM-8E multiplexer, the PSM-8E multiplexers and fiber connection must be
set up in a ring configuration. (See page 8.)
The device PSM-8E is designed to be connected over twisted-pair fiber to up
to eight (8) TRANSITION Networks PowerStar (or other) devices. PowerStars,
in turn, are designed to distribute 5250 protocol signals to up to seven (7)
hubs or other network devices.
Refer to TRANSITION Networks PowerStar documentation for more detail.
