26、resilient alignment sleeve FC/PC connector set (plug adaptor plug) must meet in order for it to be categorised as an EN standard product. Since different variants and grades of performance are permitted, product marking details are given in 3.5. 1.2 Intermateability Although all products conforming
27、to the requirements of this specification will intermate, the resulting level of random attenuation performance will only be ensured in accordance with Table 1 The intention is that this will be true irrespective of the manufacturing source(s) of the product. In all cases, the intermating of plug va
28、riants having different attenuation grades will result in an uncertain level of random attenuation performance. Similarly, when intermating plug variants having different return loss grades, the resulting level of return loss cannot be assured to be any better than the worst return loss grade. Table
