1.1 Product definition
This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental
performance requirements, which a singlemode fusion splice protector need to meet in order for it to be
categorised as an EN standard product.
Although in this document the product is qualified for EN 60793-2-50 type B1.1 and B1.3 singlemode fibres it
may also be suitable for fusion splice protection of multimode fibre with 125 µm diameter glass cladding and
other singlemode fibres with 125 µm diameter glass cladding at other wavelengths.
1.2 Interoperability
The installed fusion splice protector needs to fit into optical fibre splice cassettes or splice trays. This European
Standard specifies the following physical interface dimensions:
- cross sectional profile with width, height or diameter(in millimetres);
- length (in millimetres).
1.3 Expected performance
In this European Standard, the performance of the fusion splice protector is given with selected fibres as
specified in Annex A.
1.4 Operating environment
The tests selected combined with the severities and durations are representative of an outdoor enclosed
environment defined as category U in EN 61753-1. To ensure that the product can be used in closures, boxes
or street cabinet for categories C, A, G and S (as defined EN 61753-1) the specified lower temperature is
extended to -40 °C and requirements for temporary flooding have been added.
1.5 Reliability
Whilst the anticipated service life expectancy of the product in this environment is at least 20 years,
compliance with this specification does not guarantee the reliability of the product. This should be predicted
using a recognised reliability assessment programme.
1.6 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.
