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. Its primary role is in Passive Optical Networks (PON), which are the foundation of. In the backbone of modern Fiber-to-the-Home (FTTH) networks, optical splitters serve as the unsung heroes that enable cost-efficient connectivity for millions of subscribers. A fiber-optic splitter, also known as a beam splitter, is based on a quartz substrate of an integrated waveguide optical power distribution device, similar to a coaxial cable transmission system.

The equation below can be used to estimate the split ratio and insertion loss for a typical split port. SR=Pi/Pt×100% IL= -10xlog (SR/100)+Гe where IL = splitter insertion loss for the split port, dB Pi = optical output power for single split port, mWExcess loss is the ratio of the optical power launched at the input port of the splitter to the total optical power measured from all output ports. Insertion loss tells you how much weaker the signal becomes after passing through the splitter. Let's say you have a laser output at 0 dBm (which is 1 milliwatt of optical power). A passive optical splitter divides an incoming light signal across two or more output ports.
