Comprehensive Guide to Optical Splitters
An optical splitter is a crucial passive fiber optic device that splits and combines optical signals. It can distribute the optical energy transmitted through
Chip-based optical splitter
Some optical splitters, specifically PLC (Planar Lightwave Circuit) splitters, contain an optical chip, while traditional FBT (Fused Biconical Taper) splitters do not.Optical Splitter Types and Chip UsageFBT Splitters: These are made by fusing and tapering optical fibers together. They are purely passive devices and do not contain any chips. The splitting occurs through the physical fusion of fibers, and the device relies solely on light physics to distribute signals . PLC Splitters: These use a Planar Lightwave Circuit chip, which is a micro-optical element fabricated on a quartz or silica substrate. The chip contains integrated waveguides that precisely split a single optical signal into multiple outputs. The PLC chip is manufactured using semiconductor techniques such as photolithography, etching, and ion implantation, allowing for uniform and accurate signal distribution across many channels . The chip is typically housed in a cassette or splitter box for easy installation in FTTH networks .How the Chip WorksThe optical chip in a PLC splitter manipulates light using waveguides etched onto the substrate. It ensures uniform splitting ratios, low insertion loss, and high spectral uniformity. Fiber arrays are coupled to the chip at both ends, and precise alignment is critical for performance . This design allows PLC splitters to support high split ratios (e.g., 1x32, 1x64) efficiently, which is difficult to achieve with FBT splitters.SummaryFBT splitters: No chip, passive fiber fusion method.PLC splitters: Contain an optical chip that integrates waveguides for precise signal splitting.Function: Chips in PLC splitters improve uniformity, scalability, and reliability in fiber optic networks, especially for large-scale FTTH deployments . Thus, whether an optical splitter contains a chip depends on the type: only PLC splitters incorporate an optical chip, while FBT splitters remain purely passive.
