Requirements of the sectional specification IEC 60794-3 for duct, buried, aerial and lake, river
27、 crossings and coastal applications cables are applicable to cables covered by this standard. This standard does not cover methods of cable repair nor repair capability, nor does it cover cables for use with lake, river crossings and coastal applications line amplifiers. Clause 4 of this standard de
28、scribes a blank detail specification for optical telecommunication cables to be used for lakes, river crossings and coastal applications. It incorporates some minimum requirements. Annex A describes a blank detail specification which may be used to prepare detail specifications. Annex B describes th
29、e cable construction. Annex C describes a blank detail specification for ISO/IEC 24702 applications (MICE). The parameters specified in this standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of suitable standards. Acceptance
30、criteria are interpreted with respect to this consideration (see IEC 60794-3, Clause 9). The number of fibres tested should be representative of the cable design and should be agreed between the customer and the supplier. 2 Normative references The following referenced documents are indispensable fo
