EVS-EN IEC 62148-1:2018

IEC 62148-1:2017(E) aims to assure interchangeability in physical interfaces between fibre optic active components and devices supplied by different manufacturers, but it does not guarantee operation between such devices. This second edition cancels and replaces the first edition, published in 2002, and constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: addition of a free space optical coupling interface in Clause 5.
