Remember the distance of 1000BaseSX.

This is multimode fiber using 62.5- and 50-micron core; it uses a 780-nanometer laser and can go up to 260 meters.
Remember what is needed to use Fast Ethernet.

You should know all that is required to run fullduplex Ethernet. You need to have two 10Mbps or 100Mbps paths, two full-duplex compatible NICs, loopback disabled, collision detection disabled, the correct software drivers that support two simultaneous data paths, and an adherence to Ethernet distance standards.
Remember the distance limitation for Cat 5 cabling.

The distance limitation for Category 5 cabling is 100 meters, or approximately 300 feet.
Key Terms and Concepts

1000BaseCX

Copper shielded twisted-pair that can run only up to 25 meters.
1000BaseT

Category 5 or 6, using four-pair UTP wiring, which can run up to 100 meters.
1000BaseSX

Multimode fiber using either 62.5- or 50-micron cores. This cable uses a 780-nanometer laser and can go up to 260 meters before losing signal strength.
1000BaseLX

Single-mode fiber using a nine-micron core, a 1300-nanometer laser, and can go up to 10 kilometers before losing signal strength
