They are constructed by fusing and tapering two fibers together. Typical excess losses are as low as 0. 2dB, while splitting ratios are accurate to within ±5 percent at the. While we do sell pre-terminated fiber optic assemblies, many people still ask us "how do you fuse fiber optic cables together?" The answer lies in splicing, both fusion and mechanical. Whether you're a professional technician or a DIY enthusiast, understanding the process of fusion splicing fiber. This technical note will describe how a fused optical fiber coupler works and how it is made. Once an understanding of this has been obtained, some of the principals of operation will be made clear at once (bi-directionality, for example). RFS is certificated against ISO 9001 and ISO 14001. This method provides a simple, rugged, and compact method of splitting and combining optical signals. Fusion splicing is lower per connection; however, the initial investment is much.
