44、 Single mode optical fibres are widely used for communication purposes and cabled to satisfy the functional requirements of the installation environment. For duct installation, the environment and infrastructure can be varied and may also involve the use of single and multiple subducts. Directly bur
45、ied cables may be installed by a variety of methods such as ploughing, trenching and moling with different environments and infrastructure. This may involve specific cable design solutions based on either light, medium or heavy armouring. It is recognised that certain designs of cable for direct bur
46、ied applications involving light armour may also be suitable for duct installation. The functional requirements and test methods featured in this specification are based upon adherence to established and recognised instal- lation techniques such as those highlighted in the informative annex C (Guide
47、 to the installation of optical fibre cable) of EN 60794-1-1. 4.1 General cable description 4.1.1 Characteristics of optical fibre Single mode optical fibres are classified according to their operational wavelength and dispersion characteristics. The fibres covered by this specification are categori
48、sed as type B and described in IEC 60793-1-1. The predominant fibre types featured in this specification include, dispersion unshifted (B1.1, B1.3), dispersion shifted (B2) and non-zero dispersion (B4). Unless otherwise specified, requirements of applicable European single mode fibre standards (EN 1
49、88000, EN 188100, EN 188101 and EN 188102) have to be used in this standard. Optical fibres are inherently robust and strong, but the strength can be drastically reduced due to the combination of environmental conditions, unavoidable microscopic surface flaws introduced during fibre manufacture and stresses imposed on the fibre during handling, cabling and installation. The strength degradation can be
