  • How are two-way optical splitters made

    How are two-way optical splitters made

    Fused fiber splitters, also called fused biconical taper (FBT) splitters, are made by fusing two or more fibers together and tapering them to create a splitting region. This capability is crucial in telecommunications, especially in Passive Optical Networks (PONs), where fiber-optic networks must. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network Terminals (ONTs) at users' homes, splitters eliminate the need for dedicated fibers to each residence—slashing infrastructure costs while scaling network reach. The optical network system uses an optical signal coupled to the branch distribution. Rarely, there can be two inputs to provide potential redundancy of route.
