1 Scope
1.1 Product definition
This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental
performance requirements which an ODVA (factory terminated) (Open DeviceNet Vendors Association) or
ODVA fusion splice on connector (FSOC) terminated with cylindrical composite titanium APC ferrules with
one side protected by an industrial housing, an adaptor fitted with resilient alignment sleeve 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 inter mate and give the specified level of
random attenuation and random return loss performance provided the same fibre type is used. The intention
is that this will be true irrespective of the manufacturing source(s) of the product.
When intermating plug variants with different attenuation grades, the resulting level of attenuation cannot be
assured to be any better than the worst attenuation grade.
The intermating of a grade C plug with a grade B plug will result in an uncertain level of random attenuation
performance.
Table 1 — Ensured level of random attenuation
Plug variant/Attenuation grade C B
C C C
B C B
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 ODVA industrial connector is a duplex plug connector set of plug / adaptor / plug configuration with one
side having a protective shell characterised by two cylindrical, spring loaded butting ferrules of 1,25 mm
nominal diameter and a twist and lock coupling mechanism. The optical alignment mechanism of the
connectors is of a resilient sleeve style.
3.2 Plug
The plug consists of an ODVA connector interface and a housing part. These two parts have to be in the
defined position to each other (see Figures 1a), 1b) and 5) to guarantee correct mating. Sealing is made
between an o-ring (placed on the housing) and the adaptor frame. A cover (dust cap) to protect the ferrule
endface when the plug is in the unmated condition shall be provided. Sealing shall also be guaranteed
between the connector and the dust cap.
The plug features two cylindrical composite titanium ferrules and a push-pull coupling mechanism. Alternative
materials may be used for the ferrule that have directly compatible material properties, but the endface and
performance requirements shall be met under all conditions.
The plug has three male keys to provide the orientation to the duplex connector in relation with the adaptor.
The plug can be either a complete factory terminated version or a fusion splice on connector (FSOC) version.
The fusion splice is located within the sealed housing.
3.3 Adaptor
The adaptor consists of an ODVA adaptor as it is described in this specification and a duplex LF3 adaptor in
a mounting frame. Sealing is made between the connector housing and the adaptor mounting frame. The
mounting frame shall be mounted in a protected area with a gasket to ensure sealing between the adaptor
and the protected area. Preferred cut out dimensions to maintain sealing are given in Figure 3 and Figure 4.
At the rear of the adaptor there are two LF3 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.
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.

a) identification of manufacturer;
b) manufacturing date code: year / week;
c) manufacturers part number;
d) variant identification number.
