The Micro Unitube Cable (MUC) is a non-metallic, waterproof customer drop cable, consisting of low bend radius, no waterpeak G.657.A2 fibres, in a jelly-filled central tube, surrounded by aramid-yarns (as tensile strength elements) and protected by a smooth low-friction outersheath. This outdoor cable is thin, light in weight and flexible and can be installed with narrow bending radii, therefore very suitable for application in the access network. Installation: blowing into microducts.
