Fiber Splicers

A Fiber Splicer is used to fuse two optical fibers. This can be done by using the Mechanical Splicers or by using the Fiber Fusion Splicers. Fiber Splicing results in lower light loss and back reflection making it a very convenient method for splicing. GAOTek offers a wide selection of Fusion Splicers like the Fiber Splicer with Low Splicing loss, Fiber Splicers with PAS technology (FTTH) and also Fiber Fusion Splicers with Various Splicing mode.

Functions of Splicers

Fusion splicing can be done by using two methods: Mechanical Splicing and Fiber fusion Splicing method. Mechanical Splicing involves fusing two optical fibers end-to-end inside a sleeve using mechanical mechanism. There is some amount of insertion loss and back reflection in mechanical splicers. They are useful for temporary splicing requirements. The second type of splicing is the Fusion Splicing. Here the two fibers are fused or welded together using an electric arc. This is the most widely used method of splicing as this provides the lowest insertion loss and virtually no back reflection.

The Fusion Splicers are automatic machines wherein the fiber ends are prepared, cleaved and placed in alignment fixtures and by pressing the button, the fiber ends are heated with electrodes, brought together, and fused.


Mechanical Splicers are alignment devices which are used to hold the two fiber ends in a precisely aligned position, thus allowing the light to pass from one fiber into another. (Typical loss: 0.3 dB)

Fusion Splicers are automatic machines which precisely align the two fiber ends, then the glass ends are fused together using some type of heat or electric arc. This produces a continuous connection between the fiber enabling in very less transmission of light. (Typical loss: 0.1 dB)

The fusion splicers are mainly used for single mode fibers, multi-mode fibers, dispersion-shifted fibers (DSF), non-zero dispersion-shifted fibers (NZ-DSF), and erbium-doped fibers (EDF). As most of them can run on both normal and automatic splicing modes, they can be used to identify the fiber end-face and adjust parameters. The real-time technology embedded in the operating system provides user-friendly interfaces and abundant functions. The built-in large capacity battery can support long-time field work. The real-time compensation system for temperature, humidity and air pressure has greatly improved the devices against unfavorable environment changes and thus guarantees its consistency of low loss splicing in various environments.

Applications and Industries

Fiber Splicing is useful in Telecommunications or LAN and networking projects.

Mechanical Splicers are useful when the splice needs to be less permanent (allowing connection and disconnection). This is mainly used for emergency repairs and fiber-testing.

GAOTek's Fusion Splicers offer low level of loss and high degree of performance. They are widely used in long high data rate lines that are unlikely to be changed once installed. These splicers are also useful in research and development as well as to meet the production requirements. Splicing is also used to restore fiber optic cables when a buried cable is accidentally severed.
