Fusion Splicer Comparison - September 2025
Overview: A fiber fusion splicer is a device used to join two optical fibers end-to-end using an electric arc. The device aligns the core and cladding of the fibers so that they can be fused together.
The main difference between fusion splicers is the method they use to align the fibers before fusing them. The most common methods are active alignment and passive alignment. Active alignment is more accurate but also more expensive. Passive alignment is less accurate but cheaper.
Fusion splicers also differ in the type of electric arc they use. The two most common types are core and cladding alignment (CCA) and active alignment (AA). CCA fusion splicers are more expensive but offer better performance. AA fusion splicers are less expensive but have more alignment issues.
Finally, fusion splicers differ in their portability. Some fusion splicers are very large and heavy, while others are small and light enough to be carried in a backpack.
