An Analysis of Optimization of Mass Fusion Splicing of Non-zero Dispersion Fiber Ribbon

摘要

In the Japanese fiber optic network, the splicing density is very high because the typical cable segment is very short. This means that low average splice loss is important for constructing long haul networks, and carriers have considerable interest in minimizing fiber splice loss, especially for non-zero dispersion fiber (NZDF) because Japanese telecommunications carriers have recently begun installing NZDF cable for their new long haul network construction. Since the most commonly used cable structure in Japan is either a 2, 4, or 8-fiber ribbon slotted core cable, the cable segments are almost always joined using mass fusion splicing. One of the factors affecting splice loss is the mode field diameter (MFD) at the splice point following fusion. By analyzing measurements of the MFD at the splice point we optimized the mass fusion splicing program for fiber and obtained splicing performance to be similar to that of G.652 fiber ribbon.
