Plastic optical fiber (POF) (or Polymer optical fibre) is an optical fiber that is made out of polymer.Similar to glass optical fiber, POF transmits light (for illumination or data) through the core of the fiber.Its chief advantage over the glass product, other aspect being equal, is its robustness under bending and stretching.ne of the most exciting developments in polymer fibers has been the development of microstructured polymer optical fibers (mPOF), a type of photonic crystal fiber. POF fiber also has applications in sensing. It is possible to write fiber Bragg gratings in single and multimode POF.
What is WCF. Windows Communication Foundation (WCF) is an SDK for developing and deploying services on Windows. WCF provides a runtime environment for your services, enabling you to expose CLR types as services, and to consume other services as CLR types. WCF is forthcoming Microsoft technology for service-oriented applications; it is designed to address these requirements. WCF is part of .NET 3.0 and requires .NET 2.0, so it can only run on operation systems that support it.
