FieldShield Aerial 14/10 Microduct is a 14mm diameter, self-supporting (figure-8 style) microduct intended to deploy fiber the same way an aerial drop is installed. Designed to comply with North American storm and ice loading standards, the strength member makes FieldShield Aerial 14/10 Microduct the solution for spanning up to 500 feet (152.40 m). The FieldShield Aerial 14/10 Microduct supports FieldShield Pushable Optical Fiber up to 5.5 mm in diameter.
