Connect Network Cables to the Module Port
The network cables identified in the table below should be used with the
SMC TigerSwitch modules.
Port Type Cable Type Length Limits
Fiber-Optic Cables
1000BASE-SX 62.5/125 µm or 50/125 µm core/
cladding diameter, graded-index,
multimode fiber-optic cables that
are fitted with SC connectors—the
cables must comply with the ITU-T
G.651 and ISO/IEC 793-2 Type A1b
or A1a standards.
•62.5 µm cable:
– 160 MHz*km = 220 meters
– 200 MHz*km = 275 meters
•50 µm cable:
– 400 MHz*km = 500 meters
– 500 MHz*km = 550 meters
1000BASE-LX single-mode cables fitted with SC
connectors—the cables must
comply with the ITU-T G.652 and
ISO/IEC 793-2 Type B1 standards.
The multimode cables specified for
the 1000BASE-SX module may also
be used, but a mode conditioning
patch cord may be needed — see
“Mode Conditioning Patch Cord”
on page 8 for more information.
• single-mode cable - 5 kilometers
• multimode cable - 550 meters
100BASE-FX 62.5/125 µm or 50/125 µm core/
cladding diameter, graded-index,
multimode fiber-optic cables that
are fitted with SC connectors—the
cables must comply with the ITU-T
G.651 and ISO/IEC 793-2 Type A1b
or A1a standards.
• 2 kilometers for full-duplex
connections
• 412 meters for half-duplex
connections
Note: The SMC6624M switch does
not support half-duplex operation
for the modules.
Twisted-Pair Cables
100/
1000BASE-T
Category 5 or better, 100-ohm UTP
or STP balanced cable. For 1000
Mbps (Gigabit) operation,
Category 5E cabling or better is
recommended.
Note: For 1000 Mbps operation, all
four wire pairs are used for data
transmissions.
100 meters
Note: The 100/1000BASE-T module
is compatible with the IEEE 802.3ab
standard including the “Auto MDI/
MDI-X” feature, which allows you
to use either straight-through or
crossover twisted-pair cables for
connection go any network device
including end nodes, such as
computers, or to other switches,
hubs, and routers.
