  • Splitting ratio of telecommunications optical splitter

    Splitting ratio of telecommunications optical splitter

    A split ratio describes how many output ports a splitter has, and how evenly the input optical power is distributed across those ports. For example, a 1:32 splitter takes 1 input signal and splits it into 32 equal (or nearly equal) output signals. 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 guide. Optical splitters, encompassing FBT (Fused Biconical Taper) couplers and PLC (Planar Lightwave Circuit) splitters, are prevalent passive optical devices designed to divide fiber optic light into multiple segments based on a specified ratio. Bandwidth is shared amongst customers in a PON, and the bandwidth received by a customer is not. There are a multitude of split ratios available. Let's dive into the key considerations.
