1.1Product 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. 1.2Intermateability 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. 1.3Operating 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. 1.4Reliability 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. 1.5Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme.
