The splitter evenly distributes the incoming signal to all the connected lines, ensuring reliable connectivity. The optical network system uses an optical signal coupled to the branch distribution. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network. Fiber optic splitters are critical components in telecommunications, providing an efficient way to distribute optical signals across multiple paths. Let's delve into their working mechanism. There are many types of distribution, 1 × 2, 1 × 4, 1 × N, or 2 × 4, M × N.
