Fibre optic connector optical interfaces - Optical interface standard single mode angled physically contacting fibres Ingestion-build-82396 BS EN 4855‑01 on ECO1 Scope The document defines a set of prescribed conditions that must be maintained in order to satisfy the requirements of attenuation and return loss performance in a randomly mated pair of fibres. Performance grades are classified into four categories for attenuation and one for return loss measurements.
