3 Things to Look for When Choosing Fibre Optic Patch Cables

1. Which fibre mode does your network use?

Your network will either use single-mode or multi-mode fibre. This mode affects the way your network works and the cables you can use on it.

So, you need to know which mode you use before you choose patch cables. If you use the wrong mode, then the cable probably won’t work.



Single-mode cables, classified on an OS scale, are easier to buy as you only have a couple of options to choose from. However, you get more choice of multi-mode leads. These cables have an OM scale. Typically, they have more advanced performance levels as they move up the scale. For example, an OM3 cable is more advanced than an OM1 lead.

So, as well as choosing the right fibre optic mode, you also need to choose the right level of cable for your system. A cable should be able to work with your equipment, network speed, bandwidth needs and distance requirements.

2. Which type of connection do you need?

Fibre optic patch cables don't all have the same connectors. Some even have different connectors at each of their ends.

For example, some connectors use a push and pull snap connection. Others screw into place when you attach the cable.

So, you have a choice to make here as well. You have to choose cables that have the right end connectors to attach to your equipment and system.

You also need to think about the size of the connection when you buy cables. Some connectors come in different sizes, so you need to make the right match.

Don't forget to check the connection that the cable has to make. Sometimes, you need a simplex connection where the patch cable has just one connector.

However, if you need a cable that can work with data in and data out connections, then you might need a duplex product. These cables have two connectors at the end rather than one.

Duplex connectors can work on simplex systems—you just insert one of the connectors to hook the cable up. However, simplex cables are no use on systems that need dual connectors. So, check out your exact connection needs before you buy.

3. Which kind of jacket is best for your application?

Fibre optic patch cables have different kinds of coverings, or jackets. They use different materials and different colours.

Think about the type of jacket you need for your application. Jackets can affect the way the cable works, how well it lasts in its environment and how robust it is in extreme conditions.

For example, a simple PVC jacket is a good option for standard installations in regular environmental temperatures with good ventilation. They are flexible, so you shouldn't have any problems installing them in the right position for your build.

However, if you need to add some fireproofing to your cables, then less flexible low smoke zero halogen jackets are a better option. These cables won't emit toxic fumes if they burn because they contain flame-retarding materials.

You should also think about any external stress that the cables might be put under. Regular materials might get crushed or break under pressure.



If this is a concern, then you can buy products with more rugged and robust jackets. You can also buy products designed to withstand exposure to some chemicals and some that are waterproofed. So, if you have specific needs or an unusual environment, look for cables that can cope.
