(OBR)˗OVERVIEW AND APPLICATIONS
■Optical communications technology is rapidly evolving to meet the ever-growing demand for ubiquitous connectivity and higher data rates. As signaling rates increase and modulation schemes become more complex, guaranteeing a high-fidelity optical transmission medium is becoming even more critical. Additionally, modern networks are relying more on photonic integrated circuits (PICs) based on silicon photonics or other developing technologies, introducing additional variables into the design and deployment of robust high bandwidth optical systems. Measurement and full characterization of loss along the light path is a fundamental tool in the design and optimization of these components and fiber optic networks.
■Different types of reflectometers are available to measure return loss, insertion loss, and event location for different types of optical systems. While optical time domain reflectometers (OTDRs) are a standard tool for medium to long span fiber optic networks, optical backscatter reflectometry (OBR) offers a unique combination of ultra-high spatial resolution and sensitivity that make it a very important tool for shorter fiber spans, modern photonic integrated circuits (PICs) and silicon photonics.
