Scope

This part of IEC 61753 contains the minimum test and measurement requirements and severities
which a fibre optic circulator as specified by IEC 62077 should satisfy in order to be categorized
as meeting the requirements of circulators used in controlled environments as specified in
IEC 61753-1. The requirements cover non-connectorized single-mode fibre optic pigtailed
circulators for category C used in controlled environments.

Test

All test methods are in accordance with a specific IEC 61300 standard, of which parts applicable
to this standard are mentioned in 5.2 (see Table 2).
The samples shall be terminated onto single-mode fibres as per IEC 60793-2-50:2008 category
B1.1 or B1.3 or B6 in either coated fibres (primary and secondary) or reinforced cable format as
per IEC 60794-2-50.
Table 1 is intended to provide guidance on the wavelength ranges of the various spectral bands.
It is not intended for specification. Values of operating wavelength used in performance
verification shall be specified between the customer and supplier or shall be as defined in the
manufacturer’s specification.
