While it is possible to split an optical cable, there are several challenges and limitations to consider: When an optical signal is split, it necessarily reduces the signal strength. This can lead to signal attenuation, which can result in errors, data loss, or even. 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. This process is crucial for applications like Passive Optical Networks (PONs), where the goal is to deliver the same signal to various endpoints, such as multiple homes or offices. In principle, an optical cable can be split, but it's not as simple as just cutting the cable and attaching multiple devices. Each fiber is composed of a core, cladding, and a protective outer coating. FBT splitters are one of the earliest types of fiber optic splitters. Conversely, it can also combine multiple signals into one.
