What is Fiber Optic Splice Closure

What is Fiber Optic Splice Closure?

This article answers the question “what is fiber optic splice closure?” in the context of fiber optic cable installations. Essentially, it is a type of enclosure for fiber optic cables. They are typically used at the “tap” location of aerial FTTH fiber optic cables. They provide a protective enclosure over the spliced fiber while also protecting the Outdoor Fiber Splice Box parts.

Fibre Dome Enclosure

The horizontal type of fiber optic splice closures is the most common type. They resemble a flat box or dome and provide enough space for fiber optic cable splicing, also have the optical splitting ability. They can also be aerially mounted and can accommodate max capacity 144 or 288 of fiber splice. Horizontal Fiber Optic Closure are waterproof and are designed to withstand temperatures ranging from -40degC to 85degC and up to 106 kph of pressure. They are made from high tensile construction plastic, PC,PP and ABS raw material.

Another factor to consider when choosing a Fiber Optic Splice Box is its cable port capacity. This refers to the number of ports available for terminating cables. The number of ports in a fiber optic closure will depend on the amount of cable employed in a network. If the network uses drop or branch cables, then a small port will work just fine. But if a large number of drops or branch cables are being used, the closure may only handle a small number of fibers.

To protect a fiber optic splice, a Fiber Sleeve should be used. Usually, these sleeves are installed on the fiber before a fusion splice is made. Fiber Optic Sleeve is recommended for this task. Installing the Fiber Splice Sleeves is easy. Once it is on the fiber, it covers the exposed fiber. Then it is placed in an oven to shrink it around the splice joint.
