Key Differences

Core Size

When you pick a Multimode Cable, core size is important. The core is the middle part where light moves. There are two main core sizes: 62.5 microns and 50 microns. OM1 has a 62.5-micron core. OM2, OM3, OM4, and OM5 all use a 50-micron core. Core size changes how much data you can send. It also decides what equipment you can use.

A bigger core, like OM1, works with old equipment. It is also easier to put in. But it cannot go fast or far. The 50-micron core in OM2 and newer types lets you use new transceivers. You can get faster speeds. If you want to upgrade, pick a cable with a 50-micron core. This gives you better speed and works with new gear.

Tip: Check your hardware before you pick a core size. The wrong core can slow your network and cause problems.

Bandwidth

Bandwidth tells you how much data your cable can carry. More bandwidth means faster speeds and better connections. Each Multimode Cable type has its own bandwidth. Bandwidth is measured in MHz·km. OM1 has the lowest bandwidth. OM4 and OM5 have the highest.

• OM1 and OM2 are good for simple office and school networks.
• OM3 and OM4 work well in fast data centers and backbones.
• OM5 is made for new networks that need more channels.

Bandwidth affects how fast your network can go. Multimode fibers send many signals at once. This means you get higher speeds with less loss. When you plan your network, match the cable's bandwidth to your needs.

Note: Cables with more bandwidth cost more. But they last longer and work better. Buying OM4 or OM5 can save money later.

Distance

Distance is important when you choose a Multimode Cable. Each type can go different lengths at different speeds. If you use a cable that is too long, you lose signal and speed. Modal dispersion happens when light spreads out in the fiber. This can cause problems if the cable is too long.

OM1 can do 10 Gigabit Ethernet up to 33 meters. OM2 can go up to 82 meters. OM3 is made for laser gear and goes up to 300 meters. OM4 can do 10Gbps up to 550 meters and 40/100Gbps up to 150 meters. OM5 is for very fast networks and can use more channels.

OM3 fiber can do 10 Gigabit Ethernet up to 300 meters.

OM4 fiber can do this up to 550 meters, which is great for big jobs.

OM5 is best for new networks that need more channels and distance.

If your network is big, like a campus or data center, use OM3, OM4, or OM5. These work for longer runs and faster speeds. For short office links, OM1 or OM2 may be enough.

Tip: Multimode fiber is best for short and medium distances. For longer runs, use single-mode fiber to keep your signal strong.

Color Coding

Color coding is very important for managing multimode cables. You use jacket colors to tell cable types apart fast. This helps you avoid mistakes in your network. Each multimode fiber type has its own color. These colors are set by industry rules. This makes it easier when you set up, upgrade, or fix big networks.

OM1 and OM2 cables have orange jackets. OM3 and OM4 use aqua jackets. Sometimes OM4 uses violet to stand out in busy places. OM5 cables are lime green. This is the newest type for advanced uses.

Why is color coding important for your network?

You can spot cable types right away. This saves time and stops confusion when you install or upgrade.

You can fix problems faster. This means less downtime and fewer service breaks.

You keep things the same for all teams. This helps everyone follow the same rules and make fewer mistakes.

If you know jacket colors fast, you keep things neat in crowded racks and patch panels. You stop unplugging the wrong cable and keep cables in order.

You make things more organized in busy places.

You make fewer mistakes when fixing cables.

You find and fix problems faster, so the network works better.

Color coding helps your network stay strong and grow. If you follow the rules, you lower risk and get more value from your network. Your team can work faster and smarter, which is very important for big business jobs.
