Fusion splicing is an important process related concern during the assembly of fiber optic products. Many high-end products employ technology such as DWDMs (Dense Wavelength Division Multiplexers) with their stringent loss budgets. The specifications of these devices can be met only by having an efficient fiber management scheme and low insertion losses between different fiber junctions. High-end products, like the DWDMs and EDFA (Erbium Doped Fiber Amplifiers), extensively use Single Mode Fiber (SMF) and Erbium Doped Fiber (EDF). Fusion splicing is a key process and the insertion losses need to be minimized to adhere to the loss budgets.
Initial experiments addressed the minimization of the insertion loss between SMFs. High insertion losses were obtained when an EDF was spliced to an SMF. Studies were conducted to understand the behavior of an EDF when spliced to an SMF, and the impact of the splicing parameters on resulting losses. The factors that contributed to the splice loss were studied through statistically designed screening experiments and their relative impact on the splice quality was evaluated. ‘Optimal’ settings for fiber splicing were selected. The results of these experiments are discussed in this paper.
Qualitative factors, such as those that relate to the environment, workspace, assembly tools and operators need to be considered in controlling the losses seen in fiber optic products. Quality tools, like Process Failure Mode and Effects Analysis (PFMEA), can also be applied. This paper also addresses the various areas that should be considered for an EMS provider involved in high-volume fiber optic assembly and test. Guidelines are provided for the systematic characterization of process and test related functions for fiber optic products.
