Optical fibre cables – Part 3-10: Outdoor cables – Family specification for duct, directly buried and lashed aerial optical telecommunication cables
|Publication Date:||1 January 2009|
|ICS Code (Fibres and cables):||33.180.10|
This part of IEC 60794 is a family specification that covers optical telecommunication cables to be used in ducts or direct buried applications. Requirements of the sectional specification IEC 60794-3 for duct, buried and aerial cables are applicable to cables covered by this standard.
Clause 5 describes a blank detail specification for optical telecommunication cables to be used in ducts or direct buried application. It incorporates some minimum requirements.
Detail specifications may be prepared on the basis of 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 should be interpreted with respect to this consideration (see IEC 60794-3, clause 9).
The number of fibres tested is representative of the cable design and should be agreed between the user and the manufacturer.
