The maximum length for 100BASE-FX fiber is shown in the
following table.
See “Cable Specifications” on page 30 for further information.
Note:
As a general rule, the length of fiber optic cable for a
single switched link should not exceed 2 kilometers (1.24
miles) for multimode fiber. However, power budget
constraints must also be considered when calculating the
maximum cable length for your specific environment.
5. Connecting to a 1000BASE-SX Port:
The 1000BASE-SX
module operates at 1000 Mbps, full duplex, and supports IEEE
802.3x flow control. When you connect fiber cable to a
1000BASE-SX module on the switch, be sure you use an
SC-type connector. When inserting the cable, be sure the tab
on the plug clicks into position to ensure that it is properly seated.
For fiber optic connections, use 50/125 or 62.5/125 micron
multimode fiber optic cable. If you need to connect a cable
with ST-type plugs to a device with SC-type connectors, SMC
provides an optional SC-ST converter (Part Number:
99-012034-091). Be sure to connect the converter’s TX (Rx)
port to the Rx (Tx) port on the other device. See “Cable
Specifications” on page 30 for further information.
