OPTICAL FIBRE CABLES –
Part 5-10: Family specification –
Outdoor microduct optical fibre cables, microducts and protected microducts for installation by blowing
1 Scope This part of IEC 60794 is a family specification that covers outdoor microduct optical fibre cables for installation by blowing and the associated microducts, which together make up a microduct optical fibre cable system. Although primarily designed for use with outdoor microduct applications, the cable products specified herein may be used individually for short lengths in other applications as agreed upon between supplier and customer. These may include short runs inside a building or in other outdoor applications, such as a transition between separate (unconnected) microduct systems, or from a microduct system to some other protective structure such as a cable conduit or tray. Systems built with components covered by this standard are subject to the requirements of IEC 60794-5 where applicable.
Annex A shows examples of microduct optical fibre cables and microducts. Annex B describes a blank detail specification for outdoor microduct optical fibre cables 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 requirements for microduct optical fibre cables.
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 and microducts tested shall be representative of the microduct optical fibre cable design and should be agreed between customer and supplier. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

General 4.1.1In addition to the construction requirements of IEC 60794-5, where applicable, the following considerations apply to outdoor microduct optical fibre cables and their corresponding microducts and protected microducts. The products covered in this specification shall be designed and manufactured for expected operating lifetimes of at least 20 years. The microduct optical fibre cables are designed to be installed in microducts or protected microducts and in appropriate housings. The microducts and protected microducts that are compatible for use with microduct optical fibre cables are defined in this standard. Microduct optical fibre cables are optimized for installation and operational life in these microducts. It shall be possible to install or remove the microduct optical fibre cable from microduct or protected microduct by blowing during the operational lifetime, except under the following conditions: a) products are compromised by multiple installation or removal operations; b) microducts fouled with sediment, debris or other foreign matter due to inadequate maintenance; c) microducts subsequently damaged by extrinsic factors such as diggings, earth upheavals, etc. In such cases, the affected section of microduct shall be cleared or repaired, or products replaced prior to any microduct cable installations. The microduct fitness should be verified with dimensional clearance and static pressure testing of the microduct route. SIST EN 60794-5-10:2014

– 10 – 60794-5-10 © IEC:2014 The materials in the microduct optical fibre cable, microduct or protected microduct shall not present a health hazard within its intended use.
Microduct optical fibre cables 4.1.2Microduct optical fibre cables are suitable for installation by blowing into a microduct. Although not specifically addressed by cable products specifications such as IEC 60794-2, IEC 60794-3 or IEC 60794-4, cable products specifically designed for installation by blowing into microducts may also comply with other such industry standards and specifications. However, they are often not as mechanically robust as traditional outdoor optical fibre cables and, therefore, require the use of suitable installation and handling practices to prevent damage. Ad hoc installation practices could degrade optical performance or reduce the products’ operating lifetimes.
Microduct 4.1.3A microduct suitable for installation of microduct cables is a small, flexible, lightweight tube with an outer diameter typically less than 16 mm. Compared to microduct fibre units (see IEC 60794-5-20), microduct cables are more mechanically robust, but they place greater reliance on microducts and protected microducts or appropriate closures to provide mechanical protection than do traditional cables. Therefore, a microduct shall meet the realistic impact, compression and bending requirements for an application. A protected microduct may be required. Microducts shall be able to resist pressure differences needed for installation by blowing. The microducts shall be circular and uniform in cross-section throughout their length and their inner surface may have a low coefficient of friction. Inner and outer diameters shall be specified. As an option, a supplier may provide a special lining or lubricating coating on the interior of the microduct to aid installation. These layers should not reduce the specified inside diameter of the microduct. Microducts generally are intended for benign installation within ducts or as components within a protected microduct as described in 4.1.1.3. In all cases, it shall be possible to identify each individual microduct throughout its length. When using colours they shall conform to IEC 60304. Microducts installed outdoors and not occupied shall be sealed at each end to prevent the introduction of moisture, debris, insects or other such foreign contaminants that could subsequently hinder the successful installation of cable. Microducts installed outdoors and not immediately occupied shall be tested for obstruction prior to use.
Protected microduct 4.1.4A protected microduct is one or more microducts surrounded by a protective sheath, a larger protective duct and/or an integral thick sheath such that it complies with the requirements of Clause 7. A protected microduct can provide additional crush and impact protection compared to a stand-alone microduct. This additional protection may be needed for a specific operating environment or installation method. The protective sheath may include an integrated layer of armouring or thicker outer sheath. In all cases, it shall be possible to identify each individual microduct throughout its length. When using colours, they shall conform to IEC 60304.
Microduct fittings 4.1.5Microduct fittings are components needed to physically align, connect and seal the junction between two or more sections of microduct, or to connect microduct to hardware. Multiple microducts may be connected in series in order to support extended microduct cable installation distances, or connected in a branch-type configuration with multiple output termini for a given input, within the same system. The latter may be employed in campus type local area networks (LANs) or fibre-to-the-premises (FTTP) applications to allow for additional flexibility that can support frequent changes to the physical optical distribution system. SIST EN 60794-5-10:2014

60794-5-10 © IEC:2014 – 11 –
Fittings should be appropriate to the microduct construction. Mechanical and environmental performance requirements of fittings may also require that such be tested while attached to sections of ducting (or hardware) to ensure intermateability and operational compatibility. The specific physical and material attributes of any fittings used should be agreed between customer and supplier. Microduct fittings shall be able to resist pressure differences needed for installing microduct cables by blowing. Fittings shall allow for the smooth transition of microduct cables between successive sections of microduct, or between microducts and hardware, and shall be constructed and installed to prevent jamming of the microduct cable at splice, branch or other connection points under maximum installation pressures. Successive sections of microduct may also be welded or otherwise secured together along the same longitudinal axis without the use of mechanical fittings. Such junctions shall meet the same mechanical and dimensional requirements as for joints made using mechanical fittings. Translucent or transparent materials may be used to support the identification of populated microducts, and for troubleshooting installation related issues.
Microduct hardware 4.1.6Microduct hardware includes the housings and closures that support the termination of microduct cables, to include splicing or connectorization. Because microduct cables are generally compatible with traditional outdoor fibre optic cable hardware, accounting for the relatively small size, no specific requirements for microduct hardware are included herein. In some applications, it may be appropriate to use hardware that is compatible with the microducts in order to create a sealed microduct cabling system. One example is when empty microducts are pre-installed in hardware to support future microduct cable placement. 4.2 Optical fibres There shall be no fibre splice in a delivered length unless otherwise agreed by customer and supplier. It shall be possible to identify each individual fibre throughout the length of the microduct cable. The transmission performance shall be in accordance with Annex D. 4.3 Installation performance tests
Installation conditions 4.3.1A test route may be used to verify the field performance of a microduct cable, microduct, and/or protected microduct as agreed between customer and supplier. Ambient conditions can affect installation performance and therefore should be monitored. Alternately, the supplier can provide performance data from a specified test route under specific ambient conditions using a specified installation method. Verifying that a microduct cable or microduct can be installed using a blown installation technique is critical. Any installation performance requirement shall be agreed upon between customer and supplier.
Tests applicable 4.3.2The tests that are applicable for installation performance are given in Table 1. SIST EN 60794-5-10:2014
