Optical fibre cables. Part 5-20: Family specification. Outdoor microduct fibre units, microducts and protected microducts for installation by blowing (IEC 60794-5-20:2014)

Alkalmazási terület

This part of IEC 60794 is a family specification that covers outdoor microduct fibre units and corresponding microducts and protected microducts for installation by blowing. The protected microducts are intended for duct, directly buried or lashed applications. Microduct fibre units differ from microduct optical fibre cables (see IEC 60794-5-10) in that they provide less protection to the fibres that they contain. Specifically, microduct fibre units rely on the structure of the microduct, protected microduct or appropriate housing to support installation and to provide additional mechanical protection for the optical fibre over the lifetime of the product. Systems built with components covered by this standard are subject to the requirements of sectional specification IEC 60794-5 where applicable. Annex A gives examples of microduct optical fibre units and microducts. Annex B describes a blank detail specification for outdoor microduct fibre units and the associated microducts and incorporates some minimum requirements. Detail product specifications may be prepared on the basis of this family specification using Annex B as a guide. Annex C provides normative product constructions for microduct optical fibre units, microducts and protected microducts. 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. The number of fibres tested is intended to be representative of the microduct fibre unit design and should be agreed between the customer and supplier.
