S178A Ver. 2 Core Allignment Fusion Splicer


Fusion splicing is used to physically join together two optical fiber ends. The process may vary, depending on the type of fusion splicer used. The S178 Ver.2 Single-Fiber Fusion Splicer has an active core aligning mechanism to align the fiber ends, and a controllable electric arc to melt the glass and butt the ends together. This results in a strong joint, with very low loss and very low back-reflection. To achieve good splicing results, it is essential to know both the proper use of a fusion splicer and the characteristics of optical fiber. Because all fibers are not identical, they can melt or fuse at different temperatures. Therefore, to minimize splice loss, it is important that the arc power and the duration of the fusion arc be properly adjusted. The S178 Ver.2 fusion splicer features an arc function inspection to help the user adjust these parameters.

Other intrinsic factor that contribute to the increase in splice loss are core diameter mismatch or axis offset.
core mismatch

A difference between A and B will cause a splice loss, even if d is zero
It is impossible to have perfectly centered cores, because fiber manufacturing limitations often result in small offsets. The S178 Ver.2 fusion splicer, which has an active core alignment function by observing the core position with microscope and image processor, aligns the cores of both fibers to minimize the axis offset described above.

The S178A Hand-Held Core-Alignment Fusion Splicer has been enhanced and updated to version 2. The battery is automatically charged internally when connected to AC mains power even during operation. The new illumination lamp lights up a wide area around the V-grooves and helps operation in low light environment. The redesigned and strengthened heater simplifies the protection sleeve loading process.

The S178A is equipped with a core alignment system that can complete a splice in 7 seconds and an integrated heater which can shrink a protection sleeve in 25 seconds. Although the S178A is significantly smaller and lighter in weight than previous models, its canopy design, durable metal body frame and rubber protection corners provide robust protection. This enables use in demanding environments without compromising splicing performance. Along with its rugged durability, the splicer also offers convenience. An internal battery system allows up to 200 splicing cycles (splicing/heating) and an innovative, mirror-free alignment system reduces maintenance work. It continues the FITEL tradition of quality and excellence by delivering precise and accurate splices even under rigorous field conditions.


The S178A is a versatile choice for a wide range of applications including FTTx, LAN, backbone, enterprise, long-haul installations, data-center and OEM. It is an excellent option for use in the conventional telecommunications industry, along with other industries.
