1.1   Définition du produit Cette spécification contient les exigences de performances initiales, dimensionnelles de début de vie, optiques, mécaniques et environnementales auxquelles un jeu de connecteurs (fiche/prise femelle) de type SG à alignement par une rainure en V multimodaux équipés et assemblés doit satisfaire afin d'être classé comme produit inclus dans une norme EN de produit. Les précisions concernant le marquage des produits sont données en 3.5. 1.2   Compatibilité d'accouplement Les produits conformes aux exigences de cette spécification s'accouplent entre eux et présentent le niveau spécifié de performance d'affaiblissement aléatoire et d’affaiblissement de réflexion aléatoire à condition que la même taille de cœur de fibre soit utilisée. Le but est que cela se vérifie indépendamment de la (des) source(s) de fabrication du produit. 1.3   Environnement de fonctionnement Les essais sélectionnés combinés avec leurs sévérités et leurs durées sont représentatifs d'un environnement intérieur, généralement celui que l'on trouve dans le câblage générique des locaux commerciaux, mais sans s'y limiter, comme défini dans la EN 50173 et dans l’ISO/CEI 11801 et qui est spécifié comme catégorie C de la CEI. 1.4   Fiabilité Tandis que l'espérance de vie du produit en service prévue dans cet environnement est de 20 ans, la conformité avec cette spécification ne garantit pas la fiabilité du produit. Il convient que celle-ci soit estimée en utilisant un programme reconnu d'évaluation de la fiabilité. 1.5   Assurance de la qualité La conformité avec cette spécification ne garantit pas la cohérence de fabrication du produit. Il convient qu’elle soit maintenue en utilisant un programme reconnu d'assurance qualité.

1 Scope
1.1 Product definition
This specification contains the initial, start of life dimensional, optical, mechanical and environmental
performance requirements which a terminated and assembled multimode V-groove alignment
SG connector set (plug/socket) must meet in order for it to be categorised as an EN standard product.
Product marking details are given in 3.5.

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 the same fibre core size 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 are representative of an indoor environment
typically, but not limited to, that found in generic cabling on commercial premises as defined in
EN 50173 and ISO/IEC 11801 and specified as IEC category C.

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
The SG connector is a single position duplex plug connector set of plug/socket configuration
characterised by a pair of contacting fibres of 125 µm typical diameter and a latched push - pull coupling
mechanism. The optical alignment mechanism of the connector is a V-groove. All intermating surfaces
shall be moulded from a thermoplastic polymer with a minimum flexural modulus of 1 900 MPa at
22 °C.

3.1 Plug
The plug features a rectangular housing and fibre positioning and securing mechanism together with a
coupling/de-coupling latch. It has an asymmetrical profile which controls the relative position of transmit
and receive fibres between mated connectors.

An integral cover (dustcap) to protect the fibre endfaces when the plug is in the unmated condition shall
be provided. The operation of the cover shall be automatic as the plug is inserted into and removed from
the socket.

---------------------- Page: 8 ----------------------

EN 50377-3-1:2008 - 8 -
3.2 Socket
The socket incorporates a fibre securing mechanism and two V-grooves for fibre alignment. A boot is
provided to support the cable exiting the rear of the socket. The mounting style is by a “keystone” latch.
An integral door (dustflap) to protect the fibre endfaces when the socket is in the unmated condition shall
be provided. The operation of the door shall be automatic as the plug is inserted into and removed from
the socket.

3.3 Materials
Materials which are not specified or which are not specifically described are left to the discretion of the
manufacturer.

3.4 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 in agreement with an IEC Interface Standard this is clearly stated.

3.5 Colour and marking
Marking of the product shall be in accordance with 2.6.2 of EN 186000-1:1993 in the following order of
precedence:
a) identification of manufacturer;
b) manufacturing date code: year/week;
c) manufacturers part number;
d) variant identification number.
