适用范围：This part of IEC 60794 which is a family specification covers optical self-supporting aerialtelecommunication cables. Requirements of the sectional specification IEC 60794-3 for duct,buried and aerial cables are applicable to cables covered by this standard.Self-supporting aerial telecommunication cable in this context means a cable constructionwith sufficient strength members designed to be suspended on poles and similar deviceswithout the aid of another supporting wire or conductor. ADSS cables and other constructionsintended for high-voltage applications are not covered by this standard.Detail specifications may be prepared based on this family specification.Clause A.2 contains requirements that supersede the normal requirements in case the cablesare intended to be used in installation governed by the MICE table of ISO/IEC 24702.The parameters specified in this standard may be affected by measurement uncertaintyarising either from measurement errors or calibration errors due to lack of suitable standards.Acceptance criteria shall be interpreted with respect to this consideration (see IEC 60794-3,Clause 8).The number of fibres tested shall be representative of the cable design and shall be agreedbetween the customer and the supplier.
