Blown Fibre Units
The technologies associated with Sirocco blown fibre are covered by patents
held by British Telecom (licensed to Prysmian) and Prysmian itself. These Mark 2 designs, improving
over the old Mark 1 single fibre unit solutions, are available in units ranging from 2-fibre to
12-fibre. The fibres are contained in an soft inner acrylate layer which cushions the fibres, an
outer harder layer which protects the fibre from damage and a low friction layer that assists in
improving blowing distance, which is typically up to 1,000 metres.
The Sirocco units are available in a range of lengths up to 6,000 metres, supplied in pans.
The outer layer of the 2, 4 & 8 fibre units is colour coded to provide an indication of fibre
type.
The constructional details for all of the Blown Fibre Units and the mechanical /
environmental performance standards and tests associated with the product are contained in the
attachment.
