Fibre optic communication subsystems - Part 1: Generic specification

IEC 61281-1:2017 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. This second edition cancels and replaces the first edition published in 1999. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: addition of new definitions. Keywords: fibre optic communication subsystems (FOCSs)

Lichtwellenleiter-Kommunikationsuntersysteme - Teil 1: Fachgrundspezifikation

Sous-systèmes de télécommunications fibroniques - Partie 1: Spécification générique

IEC 61281-1:2017 est une spécification générique relative aux sous-systèmes de télécommunications fibroniques (FOCS, fibre optic communication subsystem). Les paramètres définis dans le présent document constituent un ensemble minimal de spécifications, communes à tous les sous-systèmes fibroniques. Des paramètres supplémentaires peuvent être utilisés, selon les spécificités de l'application et des technologies. Ces paramètres supplémentaires seront spécifiés dans les documents appropriés, suivant le cas. Chaque paramètre spécifié est mesuré au moyen de l'un des modes opératoires d'essai. L'utilisation de ces paramètres pour la conception de systèmes est décrite dans les guides de conception. Cette deuxième édition annule et remplace la première édition parue en 1999. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: ajout de nouvelles définitions. Mots clés : sous-systèmes de télécommunications fibroniques (FOCS, fibre optic communication subsystem)

Optični komunikacijski podsistemi - 1. del: Splošna specifikacija (IEC 61281-1:2017)

Ta del standarda IEC 61281 je splošna specifikacija za komunikacijske podsisteme optičnih vlaken (FOCS).
Tu določeni parametri predstavljajo določen minimalni sklop specifikacij, ki so skupne vsem podsistemom optičnih vlaken. Glede na posamezno uporabo in tehnologijo lahko uporabite dodatne parametre. Ti dodatni parametri bodo ustrezno določeni v zadevnih dokumentih.
Vsak od določenih parametrov bo izmerjen s pomočjo enega od preskusnih postopkov. Uporaba teh parametrov za oblikovanje sistema je podana v smernicah za oblikovanje.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. Interna
