Fiber Optic Splicing
Splicing is the technique of choice whenever two optical fibers need to be firmly connected to each other. It is crucial that the attenuation losses at the splice be as low as possible and that the splice last as long as possible. This is why the fusion process is used almost exclusively today. Different types of devices are used depending on the fiber and application.

Area of Application
Pay attention to this when choosing your splicer
Where is the device going to be used?
Today, optical fibers are used in a wide variety of areas, some of which have very different requirements. When choosing your splicer, you should therefore first ask yourself to what you need to pay particular attention. In the field, you need robust devices that are easy to transport. In the data center, you may end up using fiber ribbons that require special splicers.
Which fiber do you intend to splice?
Different fiber types are used depending on the network level. Single-mode fibers are usually used in transport and metro networks that must bridge long distances. To align their small cores precisely, three-axis splicers with fiber core centering are recommended. With multi-mode fibers in access networks and LANs, the light-carrying core is larger. However, the installation of these networks requires many splices. Speed is therefore more important than precision in this case. The situation is completely different with multicore fibers, in which all cores must be precisely aligned with each other. This also requires appropriate splicing equipment.
Indoors or outdoors?
In installation and telecommunications construction, a lot of work is carried out on site at the customer’s premises or at distribution nodes and other facilities in the open air. In these cases, you require equipment that is robust and easy to transport. Our partners offer splicers that have been explicitly optimized for field use.
Current Technologies
Beyond Borders
Regardless of the area of application, the fusion splicing process is used almost exclusively today. This involves heating the fiber ends with a hot arc of up to 2,000 degrees to create permanent connections with low attenuation losses. This technology is offered in various forms, which differ primarily in the way the fibers are aligned in the device.
V-groove and single-axis devices are the simplest and cheapest versions. They are cladding centered; in addition, they are used wherever speed is required, and minor deviations are accepted. One modification of this technology includes special devices for fiber ribbons, which are becoming increasingly popular in data centers. It is important that each of the up to twelve fibers in the ribbon be connected to its counterpart with as little loss as possible.
Three-axis splicers guarantee optimum alignment in the X, Y and Z axes and thus ensure lower attenuation and higher connection quality. These devices are available in many varieties, which are optimized for different fiber types and core diameters. The positioning of the fiber ends is fully automatic in current splicers, and the machine works more precisely and efficiently than a human in this respect. Nevertheless, the operator can intervene at any time and thus always has the entire splicing process under control.
