BS EN IEC 61281-1:2018 is a generic specification for fibre optic communication subsystems
(FOCSs).The parameters defined herein form a specifiable minimum set of specifications that are
common to all fibre optic subsystems. Additional parameters can be used depending on
the particular application and technology. Those additional parameters will be specified in the
relevant documents, as appropriate.Each specified parameter is measured using one of the test procedures. The use of these
parameters for system design is given in design guides.Cross References:IEC 61290-3-2EN 61290-5-2EN 60794-1-1IEC 61274-1EN 62614IEC 61290-4-3IEC 61290-5-3IEC 61290-1-1EN 61290-10-2IEC 60793-1-41EN 61290-5-3IEC 61290-4-1IEC 61280-2-10IEC 61280-1-4EN 61290-4-3EN 61280-2-8IEC 61290-10-5EN 61290-1-3IEC 61290-5-1EN 61290-3-3EN 61280-2-1IEC 61290-10-2IEC 61280-1-3IEC 61280-1-1EN 61280-2-12EN 61290-10-3IEC 61280-4-4EN 61290-11-1EN 61280-2-3IEC 61280-2-2IEC 61073-1EN 61290-1-1IEC 61280-2-8IEC 62149IEC 61290-1-3IEC 61280-4-2EN 61280-4-1EN 61290-4-1EN 62149IEC 61290-10-3IEC 61703IEC 61753EN 61280-2-10IEC 61290-11-2IEC 61290-1-2IEC 61290-3-1IEC 61291-4IEC 61290-10-1IEC 61291IEC 61280-2-1EN 60793-1-41IEC 61290-10-4IEC 61280-2-12EN 61703EN 61290-7-1EN 61073-1EN 61280-2-9IEC 61280-2-11EN 61290-4-2EN 61290-3-2EN 61280-4-4EN 61290-10-1EN 61274-1EN 61280-2-2IEC 61280-2-3IEC 61290-4-2EN 61290-10-4IEC 62614EN 61290-5-1IEC 61290-3-3EN 61280-2-11EN 61291-2IEC 60793-2IEC 60876-1:2014EN 60876-1 (IEC 60876-1:2014) ASEN 60869-1 (IEC 60869-1:2012) ASEN 61291-1 (IEC 61291-1:2012) ASIEC 60875-1:2015IEC 60874-1:2011EN 60875-1 (IEC 60875-1:2015) ASIEC 61291-1:2012IEC TS 62538:2008EN 60874-1 (IEC 60874-1:2011) ASIEC 60869-1:2012IEC 61290-7-1IEC 61291-2EN 61280-1-1EN 60793-2EN 61290-3-1IEC 60793-2-50EN 61290-10-5IEC 61290-5-2EN 61290-1-2IEC 61290-6-1EN 61280-4-2EN 61280-1-3IEC 60793-2-10EN 60793-2-10EN 61290-6-1EN 61753EN 61291EN 61280-1-4IEC 60794-1-1IEC 61290-11-1EN 61290-11-2ITU-T Recommendation G.701:1993IEC 61280-4-1EN 61291-4EN 60793-2-50IEC 61280-2-9All current amendments available at time of purchase are included with the purchase of this document.
