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 um 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 1900 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.
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 in the following order
of precedence:
a. Identification of manufacturer
b. Manufacturing date code : year/week
c. Manufacturers part number
d. Variant identification number
