Optical Fiber Fusion Splicing and Its Applications

What is fusion splicing fiber optic?

Optical fiber splice is a fusion welded joint formed between two optical fibers. This is a permanent, low loss, high bond strength compared to other temporary joint such as a mechanical splice. Optical fiber fusion splicing plays a crucial role in the optical network.

The Ideal Fusion Splicing Process

The goal is to create a joint and a low insertion loss and mechanical strength even with long-term reliability which matches the fiber itself.

The ideal process should be fast, cheap and should not require expensive equipment. But actually, the process requires tradeoffs between various applications and needs. For example, for undersea telecommunications, long term reliability is the most important goal for fusion splicing.

The advantages

There are other approaches for interconnecting fibers such as fiber optic connectors and mechanical splices. Compared with these two fusion splice has many advantages, as explained below. Read More
