How-to Splice Fiber Optic Cable

Splicing fiber optic cable is a process that involves joining two or more fiber optic cables together. The goal of splicing is to create a continuous connection between the fibers in order to ensure optimal signal transmission. There are two popular methods fiber technicians use when splicing wire together, including mechanical splicing and fusion splicing.

Mechanical Splicing

Mechanical splicing is a quick and easy method of splicing fiber optic cable. It involves using a mechanical splice connector to align and hold the two fibers together. The connector typically contains two precision alignment sleeves that align the fibers and a mechanism to hold them in place.

To begin the splicing process, you will need to strip the protective coating from the ends of the fibers using a fiber optic stripper. Next, you will need to cleave the fibers using a fiber optic cleaver. This will create a clean, perpendicular end face on the fibers that is necessary for proper alignment.

Once the fibers have been prepared, you will insert them into the mechanical splice connector. The connector will align the fibers and hold them in place. The spliced fibers will then be protected by a clear splice protective sleeve.

Fusion Splicing

Fusion splicing is a more advanced method of splicing fiber optic cable. It involves using a specialized machine, called a fusion splicer, to heat and fuse the two fibers together. This creates a permanent bond between the fibers.

To begin the splicing process, you will need to strip the protective coating from the ends of the fibers using a fiber optic stripper. Next, you will need to cleave the fibers using a fiber optic cleaver. This will create a clean, perpendicular end face on the fibers that is necessary for proper alignment.

Once the fibers have been prepared, you will insert them into the fusion splicer. The machine will align the fibers and use an electric arc to heat and fuse them together. The spliced fibers will be protected by a clear splice protective sleeve.

It’s important to note that both methods require proper training and experience to ensure a successful splice. Incorrectly splicing fiber optic cable can cause signal loss or other issues. Always use the proper tools, equipment, and safety precautions when splicing fiber optic cable.
