FieldShield Aerial Microduct is an 8 mm diameter, self supporting (figure-8 style) microduct intended to deploy fiber the same way an aerial drop is installed with the use of either a PLP (DE 2525) or other suitable hardware. Designed to comply with North American storm and ice loading standards, the 1.5 mm copper clad steel metallic strength member makes FieldShield Aerial Microduct the perfect solution for spanning lengths up to 200 feet or lashing to an existing support strand. The FieldShield 8 mm diameter Aerial Microduct supports FieldShield Pushable Optical Fiber that is 3 mm in diameter.
