Fiber optic cable repair kit typically include the necessary tools and materials to repair damaged fiber optic cables in the field.  These kits are essential for technicians and installers who need to quickly and efficiently fix fiber optic cables to restore communication or data transmission.  While the exact contents of a repair kit may vary depending on the manufacturer and specific model, typical components might include:

Fiber optic fusion splicer: A fusion splicer is a machine used to join two optical fibers together by melting the glass ends and fusing them together permanently.

Fiber cleaver: A cleaver is a tool used to precisely cut optical fibers before splicing.  It ensures clean, flat ends for proper fusion.

Fiber stripper: A fiber stripper is used to remove the protective coating from optical fibers before splicing or termination.

Cleaning supplies: Cleaning tools such as wipes, swabs, and solutions are essential for removing dirt, dust, and contaminants from the fiber optic cables before splicing.

Heat shrink sleeves or mechanical splice connectors: These are used to protect and strengthen the spliced or repaired section of the fiber optic cable.

Fiber optic testing equipment: Tools for testing the quality and performance of the repaired section of the fiber optic cable, such as an optical power meter and an optical time-domain reflectometer (OTDR).

Protective carrying case: A durable case to store and transport the repair kit safely to different locations.

Instruction manual or guides: Detailed instructions or guides on how to use the tools and perform the repairs safely and effectively.

It's important to note that the specific components and quality of a fiber optic cable repair kit can vary depending on the manufacturer and intended use.  Additionally, some kits may be tailored for specific types of repairs or environments, such as aerial, underground, or indoor installations.  When selecting a repair kit, it's essential to consider factors such as the type of cables being repaired, the level of expertise of the technicians, and the requirements of the installation environment.

When the fiber is broken, we don't call it repair, we call it fusion. Just like the electric welding of the iron pipe, with a special machine, it is the fiberglass filaments that are fused together!

This is the optical fiber fusion splicer , a magical machine.

We need to strip the optical cable first, and we can find that the optical cable is actually an optical fiber bundle, which is composed of many small optical fibers. We use the size of the fiber bundle to mark the size of the fiber optic cable, such as 12-core fiber optic cable, 48-core fiber optic cable, and 72-core fiber optic cable. These numbers represent the number of fibers contained in the cable. Let's take a 12-core optical fiber cable as an example. If it breaks, we will strip the optical fiber cable. At the broken ends, strip all the 12-core optical fibers from the protective layer , and then follow the cable sequence one by one. put it into this machine, and the machine begins to weld.

The following picture is a schematic diagram of the optical cable after stripping. Note that the thinnest part is still colored, and it needs to be stripped again with a stripper to see the transparent optical fiber. See the back picture for the wire stripper!

The following picture shows the internal situation of the machine. Pay attention to the two probes in the middle part of the picture, that is, the discharge needle. The two ends of the broken fiber are placed on both sides, and the discharge needle discharges and the fiber is spliced!

The picture below shows a special tool for stripping optical fibers, which we call strippers.

After the optical cable is spliced, a splice box is required to protect the spliced part, so see the splice box in the figure below.
