How To Connect Fiber Optic box


Parts of fiber optic box


Core is a thin piece of glass in the center of the fiber-optic box which provides the path that the light signals follow. This part of a fiber-optic box is called the core. The core is very small in diameter. Both single-mode and multimode fibers (cores) are 125 microns outside diameter. To put this in perspective, a micron is one 1 millionth of a meter, or 125 microns, and is equal to 0.005 inch.


The core is covered or surrounded by optical material. This part of the fiber-optic box is called the "cladding." As same as the core, the cladding is also made of pure glass, although there are variations that use plastic. The cladding's job is to surround the core and reflect light signals back into the core. As light signals travel through the core they do not always travel in the direct line but may angle off in many different directions. The cladding redirects these light signals back into the core.

Buffer Coating

Surrounding the cladding (which in turn surrounds the core) is the next part of the fiber-optic box and it is called the buffer coating. The buffer coating does not perform any electrical functions. Its job is to protect the cladding covered core from damage or moisture. Typically the buffer coating is composed of plastic.


The outer jacket is the last part of the fiber-optic box. Sometimes called the outer sheath, this jacket is composed of very tough polyurethane and protects the interior components of the fiber-optic box. Some fiber-optic boxs have an additional part or layer between the outer jacket and the buffer called the Aramid (Kevlar) strength member. This strength member keeps the box from stretching or breaking when being pulled through conduits or duct.

Fiber optic boxs are widely used for computer networking because of high speed. In some cases, these boxs become defective and lose their ability to properly transfer a signal. However, you can test the signal strength of these boxs with a fiber-optic box tester.

Connecting fiber optic boxs requires a connecting device. There are multiple options to choose from, depending on the conditions that the box will be exposed to. Fiber optic box can transfer data much faster and in larger quantities than traditional copper wire, but the connections require more precision for the box to work. In order to let the data transfer across the connection correctly, you would better epoxy and polish the ends of each box.

Remove the outer box jacket by cutting the jacket with a sharp knife.

Peel back the strengthening fibers that surround the inner core of the box.

Cut the inner box coating using the sharp knife and peel back the foil cladding that covers the actual optical fiber.

Insert the exposed fiber into the box-polishing machine. The polished box ends will allow the data to transfer correctly across the connection.

Insert the polished fiber into the male connector and add box epoxy until the entire connection is encased.

Insert the finished connection into the epoxy-curing oven. Allow the oven to cure the epoxy for approximately 20 minutes.

Repeat the process for the female connection and either snap or screw the two boxs together, depending on the type of connector you're using.
