Fibre optic interconnecting devices and passive components – Fibre optic
circulators – Generic specification
Scope
This document applies to circulators used in the field of fibre optics bearing all of the following
features:
– they are non-reciprocal optical devices, in which each port is either an optical fibre or fibre
optic connector;
– they are passive devices in accordance with the categorization and definition provided in
IEC TS 62538;
– they have three or more ports for directionally transmitting optical power.
An example of optical circulator technology and application is described in Annex A and
