1 Scope
1.1 Product definition
This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental
performance requirements that an SC-RJ connector set with one side protected by an industrial housing with the
fibres terminated with cylindrical zirconia PC ferrules, an adaptor fitted with resilient alignment sleeves and
patchcord shall meet in order for it to be categorised as an EN standard product. The product is rated IP67.
Since different variants are permitted, product marking details are given in 3.6.
1.2 Intermateability
Products conforming to the requirements of this specification will intermate and give the specified level of
random attenuation and random return loss performance, provided that the same fibre type is used. The
intention is that this will be true irrespective of the manufacturing source(s) of the product.
1.3 Operating environment
The tests selected combined with the severities and durations, specified as category I, are intended to reflect,
although they do not necessarily satisfy all the requirements of the boundary conditions of M I C E .
3 3 3 3
1.4 Reliability
Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with
this specification does not guarantee the reliability of the product. This should be predicted using a
recognised reliability assessment programme.
1.5 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.

3 Description
3.1 General
The SC-RJ industrial connector is a duplex plug connector set of plug / adaptor / plug configuration with one
side having a protective shell characterised with two cylindrical, spring loaded butting ferrules of 2,5 mm
nominal diameter and a latched coupling mechanism. The optical alignment mechanism of the connectors is
of a resilient sleeve style.
3.2 Plug
The plug consists of an SC-RJ connector interface and a housing part. These two parts have to be in the
defined position to each other (see Figure 1 and Figure 3) to guarantee correct mating. The sealing is made
between a gasket or o-ring (placed on the housing) and the adaptor frame fixed by two clamps. A cover (dust
cap) to protect the ferrule endface when the plug is in the unmated condition shall be provided. The sealing
shall also be guaranteed between the connector and the dust cap.
The plug features two cylindrical full zirconia ferrules and a push-pull coupling mechanisms. Alternative
materials may be used for the ferrule that have directly compatible material properties as zirconia, but the
endface and performance requirements shall be met under all conditions.
The plug has three male keys. Two of them are used to limit the relative rotation between mated SC simplex
plugs and one gives the orientation to the duplex connector.
However, no primary pre-alignment is provided.
3.3 Adaptor
The adaptor consists of an SC-RJ adaptor as it is described in EN 50377-6-1 and EN 50377-6-2 and a
mounting frame. These two parts have to be correctly positioned in relation to each other (see Figure 2 and
Figure 3) to ensure sealing. The mounting frame itself shall be mounted onto an equipment (e.g. on a sealed
box) with a gasket to guarantee the sealing between adaptor and whole used equipment. Preferred cut out
dimensions to maintain sealing are given in Figure 3.
At the rear of the adaptor, there can be either an SC-RJ or two SC simplex connectors.
The adaptor consists of two zirconia ceramic resilient alignment sleeves and two push-pull coupling
mechanisms, one for each sleeve. Alternative materials may be used for the sleeve that have directly
compatible material properties as zirconia but the performance requirements shall be met under all
conditions.
The adaptor housing has three female keys. Two of them are used to limit the relative rotation between
mated SC simplex plugs and one gives the orientation to the duplex connector.
Covers (dust caps) shall be provided to protect each duplex port of the adaptor.
3.4 Materials
Materials which are not specified or which are not specifically described are left to the discretion of the
manufacturer.
3.5 Dimensions
Outline dimensions and other dimensions necessary to ensure intermateability or which affect performance
are specified. All other dimensions are left to the discretion of the manufacturer. Where the mating face limit
dimensions are not in agreement with an EN interface standard this is clearly stated.
