A fiber optic closure is a small box that houses the sensitive areas of your network. Spliced areas need to be protected from dangers like pressure, extreme temperatures, insects and critters, moisture and more. A splice closure is an excellent way to do this and there are many different types of these closures available, depending on placement and capacity.

When choosing a fiber optic closure, consider what type of network you are installing. If you are installing FTTH, look for a family of outside plant closures that offer the flexibility you need as your business grows. This can save you time in the field, because you will have a variety of designs that work with your network architecture.

You also want to consider the re-entry requirements of your network. Some closures require frequent re-entry and others don’t. You can find closures that are easy to re-enter, but it’s important to double-check the cable compatibility of your network before you choose.

The other main consideration is the size of your network. If you are installing a large network, the capacity of your splice closures will be a crucial factor in how quickly your network can expand. Make sure you are purchasing a splice closure with adequate space for your splice trays. This will save you time and money in the long run. Also, the ability of a splice closure to manage thermal expansion and contraction is critical. Lastly, it’s important to ensure that the termination system is durable enough to handle the stress that can occur in high-speed installations.
