Abstract
A bend insensitive fiber optic cable includes a singlemode fiber, a buffer layer surrounding the fiber wherein a thickest component of the buffer layer has an elastic modulus greater than 515 MPa (75,000 psi), and a jacket surrounding the buffer layer, wherein the jacket has a thickness of at least 1.2 mm. In one preferred embodiment, the buffer layer includes a nylon 12 resin with a nominal elastic modulus of approximately 218,000 psi. In this embodiment, an inner thin component of the buffer layer is made of an ethylene/ethyl acrylate resin so as to facilitate stripping of the buffer layer away from the fiber.
