Description (English):

IEC 61300-2-43: 2022 aims at screening single-mode physical contact (PC) optical fibre connector plugs of an optical fibre patch cord or an optical fibre pigtail in terms of return loss, thus ensuring minimum return loss when the connector plugs are randomly mated with each other in the field. This document is intended to apply to cylindrical ferrule connector plugs. This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: addition of Clause 3 containing terms, definitions, and abbreviated terms.

Abstract

Overview

IEC 61300-2-43:2022 is the third edition of an IEC test method for screen testing return loss of single‑mode PC optical fibre connectors. The standard defines a screening procedure for cylindrical‑ferrule physical‑contact (PC) connector plugs on patch cords and pigtails to ensure a designed minimum return loss when connectors are randomly mated in the field. This 2022 edition is a technical revision and adds Clause 3 with terms, definitions and abbreviated terms.

Key topics and technical requirements

Purpose: screen connector plugs to guarantee minimum return loss performance when randomly mated (patch cords that pass will meet the designed minimum return loss in >99% of cases, Annex A).
Scope: single‑mode, PC optical fibre connectors with cylindrical ferrules (domed, non‑angled end faces).
Test concept: use a pair of reflection standard cords (RSCs) with a reflection standard plug (RSP) to screen DUTs so that the mated RSCs present return loss several dB better than the design threshold.
Measurement methods: example procedure uses an optical continuous wave reflectometer (OCWR); the method can be adapted to other return‑loss measurement techniques in accordance with IEC 61300‑3‑6.
Required apparatus (Clause 5): Source (S), Detector (D), Temporary Joint (TJ), Termination (T), Branching Device (BD), RSC/RSP.
Critical performance limits and guidance:
- TJ return loss at least 10 dB better than the maximum return loss to be measured; fusion splice recommended for >50 dB measurements.
- Termination return loss at least 20 dB better than the maximum to be measured; suggested terminations include angled ends (minimum 12°), index‑matching material, or attenuation (e.g., mandrel wrap).
- BD should have stable split ratio, low PDL (recommended
