scope:

This part of 60794 is a family specification that covers optical telecommunication cables to be used as underwater cables for lake and river crossings. Requirements of the sectional specification IEC 60794-3 for duct, buried, aerial and lake- and river-crossings 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- and river-crossings line amplifiers. Clause 5 of this standard describes a blank detail specification for optical telecommunication cables to be used for lake and river crossings. It incorporates some minimum requirements. Detail specifications may be prepared based on this family specification. 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 criteria are interpreted with respect to this consideration (see IEC 60794-3 Clause 9). The number of fibres tested is representative of the cable design and shall be agreed between the user and the manufacturer.
