SFU

The Smooth Fibre Unit (SFU) consists of a bundle of low bend radius, no waterpeak G.657.A1 fibres, encapsuled by a dry acrylate layer and protected by a smooth, slightly ribbed polyethylene outersheath, for application in the access network. Installation: blowing into microducts of 3.5mm. or 4.0mm. (inside diameter)
