IEC 61280-2-1:2010(E) describes the test procedures applicable to digital fibre optic communication and data systems. The object of this test procedure is to measure the minimum and maximum optical powers required and allowed at the optical input port of a fibre optic system to ensure its operation within specified limits. Another objective is to verify that the guaranteed error performance is obtained at the minimum and the maximum optical input powers specified by the terminal equipment manufacturer. The main changes with respect to the previous edition are:
- revised to include the requirements associated with data communication equipment, regenerators and amplifiers;
- the term "jumper lead" has been replaced by "test cord";
- a section for definitions has been added;
- a section on measurement uncertainties has been added.
