Standard Specification for Rubber Insulating Sheeting Ingestion-build-202139 test and measurement requirements and

test and measurement requirements and severities which a fibre optic pigtailed 1 490 / 1 550 nm downstream and 1 310 nm upstream wide wavelength division multiplexing (WWDM) passive optical network (PON) device must satisfy in order to be categorized as meeting the requirements of category C (controlled environments)

Product committees should therefore consider whether there is a justification for applying this standard in their product/product family standards (see also Clause 4)
