Cut off wavelength for a hole4/2/2024 Cut off wavelength reduces the numbers of bends in fiber, so the cut off wavelength plays an important role in singlemode fiber at the defining the wavelength region of singlemode fiber. We all know that fiber optic cable can be putted into loose tubes or tightly coated with elastomeric or PVC or Nylon, to make tight buffered fiber or the matrix to be fiber optic ribbon. In another word, cut off wavelength above singlemode operation but it is ensured in a singlemode fiber.įiber cut off wavelength depends on the method of fixing the fiber. Well, cut off wavelength can be defined as the wavelength below a singlemode fiber wavelength and they usually acts as multimode fiber, meaning it will allow propagation of more than one mode at a time. What is cut off wavelength? When many people see the item they may ask such question.
