The choice between fusion and mechanical splicing is a key decision in fiber optic installation, as each method has different applications and cost implications.

• Fusion Splicing: This method uses an electric arc to melt and permanently "weld" the two glass fiber ends together. It provides a seamless connection with extremely low signal loss (< 0.1 dB) and minimal back reflection, making it the preferred method for long-distance, high-performance telecommunications networks and CATV. While the initial equipment cost (for a fusion splicer) is high, the cost per splice is low.

• Mechanical Splicing: This method uses a mechanical alignment device and an index-matching gel to align and hold the fiber ends together. It does not create a permanent bond, and the typical signal loss is higher (0.2 dB to 0.75 dB). Mechanical splicing is a more cost-effective option for smaller, less-critical projects or temporary repairs, as the tools are less expensive and the process is faster.

For professional installers, fusion splicing is the industry standard for creating the most reliable and high-quality connections, which is why we provide high-performance fusion splicers and associated preparation tools.
