Fibre optic communication subsystem test procedures - Digital systems. Receiver sensitivity and overload measurement1 Scope and object This part of IEC 61280 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
