This part of IEC 60794 is a family specification covering optical fibre indoor cables that deployed in short length (d" 10 m) outdoor environments. These cables generally possess the characteristics associated with indoor cable designs having the appropriate fire performance and flexibility that makes them suitable for use in premises. Because of its predicted use outdoors stability against environmental attack e.g. UV radiation and humidity (see Table 1, IEC 60794-6) is required. Typical application spaces include the extension of a short length of indoor cable outside the building such as to a NAP mounted outside the building at the house wall.
