This International Standard applies to circulators used in the field of fibre optics bearing all of the following features:<\/p>\n
they are non-reciprocal optical devices, in which each port is either an optical fibre or fibre optic connector;<\/p>\n<\/li>\n
they are passive devices in accordance with the categorization and definition provided in IEC TS 62538;<\/p>\n<\/li>\n
they have three or more ports for directionally transmitting optical power.<\/p>\n<\/li>\n<\/ul>\n
An example of optical circulator technology is described in Annex A.<\/p>\n
