1 Scope
1.1 Product definition
This specification contains the initial, start of life dimensional, optical, mechanical and environmental
performance requirements which a fully installed blown fibre protected microduct closure must meet in order
for it to be categorised as an EN standard product.
These products are suitable for installation of and use with microduct fibre units, microduct optical fibre
cables, microduct and protected microduct as defined within EN 60794-5.
1.2 Operating environment
The tests selected combined with the severities and duration are representative of an outside plant for
subterranean and/or aerial environment defined by:
• ETSI EN 300 019 series: Class 8.1: underground locations (without earthquake requirement);
• EN 61753-1: Category S: subterranean environment;
Category A: aerial environment.
1.3 Reliability
Whilst the anticipated service life expectancy of the product in this environment is a minimum of 20 years,
compliance with this specification does not guarantee the reliability of the product. This should be predicted
using a recognised reliability assessment programme.
1.4 Quality assurance
Compliance with this specification does not guarantee the manufacturing consistency of the product. This
should be maintained using a recognised quality assurance programme.
1.5 Allowed fibre and cable types
This closure standard covers all IEC standard optical fibre microducts, and protected microducts with their
various fibre capacities, types and designs. This includes, but is not limited to, optical fibre cable standard
EN 60794-5.
This product specification has only considered protected microduct cables containing microducts of same
outside diameters. There are other hybrid protected microduct cables with microducts of differing OD’s, with
too many variants to be included in this PS.
1.6 Allowed microduct connector types
This closure standard covers all EN standard microduct connectors, including: straight, reducer/enlarger
stem, reducer/enlarger, close down, liquid block, liquid block with barb end, and end stop connectors. This
includes, but is not limited to, EN 50411-2-8.
1.7 Microduct storage constraints
Microduct excess storage is not required in all air blown fibre closures. Some closure types do not have
sufficient internal space to provide storage. The need for microduct storage is provided inside the closure
when opened, typically to ensure that there is enough microduct to fulfil the following functions:
• remove the coiled microduct attached to the ‘closedown’ connectors, to a remote location, close to
blowing equipment, in the process uncoiling the microducts to aid blowing;
• provide additional microduct if repeated cut backs for connectors are planned or likely to be fitted
throughout the closure life.
The minimum microduct storage bend radius is based on the outside diameter and material selection,
typically based on 12 times the outside diameter (below 8 mm) and 20 times above. During fibre blowing the
bend radius is typically 20 times the microduct diameter.
