Fiber optic closures are amazing networking tools that power telephone networks, CATV, LANs and premises networks over incredible distances. These remarkable cables run through a variety of environments including dry, rocky, snowy and rainy locations and across continents. This impressive networking capability means that it is important to protect the cables from environmental hazards and moisture, as well as provide access for maintenance and repairs. That's where the different types of fiber optic closures come in.

The types of fiber closures vary depending on where they are used, the cable capacity and more. Knowing what kind of closure you need for your network before selecting a specific design can save time, money and effort by eliminating the need to purchase multiple closures or adapters that are not compatible.

A key aspect to consider is the ability for the closure to withstand relative motion between the cable and closure components. This includes the ability to manage thermal expansion and contraction without putting stress on the sheath or strength members of the cable. The closure design should also be able to support cable management methods by providing a design that keeps the bend radius low and eliminates unnecessary stress or damage to the cables.

You should also keep in mind that you may need to reenter your fiber optic closure more or less frequently depending on where it is placed. Look for a closure design that allows for easy re-entry and can be opened or closed with basic tools.
