CABLE SPECIFICATIONS
The physical characteristics of the media cable must meet or exceed IEEE 802.3
specifications.
Fiber Cable
MULTIMODE
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
Wavelength :
850 nM
Attenuation:
≤
3.75 dB/ 1 kilometer @ 850 nM
Fiber-optic Transmitter Power:
min: -16.0 dBm
max: -10.0 dBm
Fiber-optic Receiver Sensitivity:
min: -29.50 dBm
max: -7.2 dBm
Link Budget
13.5 dB
Typical Maximum Cable Distance:*
Full-duplex: 300 meters
Half Duplex: See page 4
*Actual distance dependent upon physical characteristics of network installation.
Copper Cable
Category 5 twisted-pair copper wire is required. Either shielded twisted-
pair (STP) or unshielded twisted-pair (UTP) can be used. DO NOT USE
FLAT OR SILVER SATIN WIRE.
CATEGORY 5:
Gauge
24 to 22 AWG
Attenuation
22.0 dB /100m @ 100 MHz
Maximum Cable Distance:
100 meters
RJ-45 Pin-out::
Pin 1=TD+, Pin 2=TD-,
Pin 3=RD+, Pin 6=RD-
Twisted pair connection requires two active pairs configured as straight
through and/or crossover. The two active pairs in an Ethernet™ network
are pins 1 & 2 and pins 3 & 6. Use only dedicated wire pairs (such as
blue/white & white/blue, orange/white & white/orange) for the active pins.
Use the the C/E-TX-SX-02 media converter to extend the distance between a
10BASE-T or a 100BASE-TX terminal device and a 10BASE-FL or a
100BASE-SX (half-duplex only) hub, switch, or router:
Or use the the C/E-TX-SX-02 media converter to extend the distance between
