They utilize a process known as 'fused biconic tapering' to divide optical signals. This involves heating and stretching two fibers until they form a single core, then pulling them apart to create a coupling region. Optical splitters offer a cost-effective and dependable solution across various fiber optic applications. They. These unassuming devices enable a single optical signal to be divided into multiple paths, making them indispensable for sharing network resources efficiently—from residential FTTH (Fiber-to-the-Home) connections to large-scale telecom backbones. This guide demystifies fiber optic splitters. Optical cables, also known as fiber optic cables, consist of thin strands of glass or plastic fibers surrounded by a protective casing.
