• OM1: OM1 is a 62.5/125 micron multimode fiber. It is used for 10 Gigabit Ethernet applications up to 33 meters.
• OM2: OM2 is a 50/125 micron multimode fiber. It is used for 10 Gigabit Ethernet applications up to 82 meters.
• OM3: OM3 is a 50/125 micron multimode fiber. It is used for 10 Gigabit Ethernet applications up to 300 meters.
• OM4: OM4 is a 50/125 micron multimode fiber. It is used for 10 Gigabit Ethernet applications up to 550 meters.
• OM5: OM5 is a 50/125 micron multimode fiber. It is used for 25 Gigabit Ethernet and 40 Gigabit Ethernet applications up to 150 meters.

2. How do you test and troubleshoot copper and fiber optic cables?

Troubleshooting copper cables

• Check for physical damage to the cable, such as cuts or breaks.
