In order to meet the market demand for all kinds of optical fiber fusion splicer products, the basic platform of optical fiber fusion splicer is designed from the perspective of product modularization. In this paper, the overall design scheme of the basic platform is given together with the system block diagram, and the main components of the basic platform are introduced in detail, and then the verification test scheme and test results are described. Experimental results indicate that the scheme is reasonable and feasible, it meets the needs of optical fiber fusion splicer products to quickly respond to the market.
