Full title and description

Fibre optic interconnecting devices and passive components — Basic test and measurement procedures — Part 2-40: Tests — Screen testing of attenuation of single-mode tuned angled optical connectors (IEC 61300-2-40:2000). This International Standard describes a screening test intended to detect tuning errors in single-mode angled connectors equipped with a tuning mechanism by measuring attenuation when mated with calibrated reference plugs.

Abstract

IEC 61300-2-40:2000 specifies a screening (sorter) test method for single‑mode, tuned, angled optical connectors that incorporates a calibrated angled “screen” plug and defined measurement setup and acceptance criteria. The procedure identifies units with unacceptable attenuation due to tuning misalignment so that only connectors meeting a defined attenuation limit are released for use.

Scope

This part of IEC 61300 applies to single‑mode angled fibre‑optic connectors that include an adjustable tuning mechanism. It defines the equipment, the calibrated angled screen plug (with known core offset), the measurement configuration (source, excitation fibre, detector, reference adaptor), and the pass/fail limits for attenuation when connectors are mated for screening against tuning errors. The test is intended to ensure that a connector, when mated randomly with similar connectors, will not exceed a specified maximum attenuation.

Key topics and requirements

• Definition and purpose of the attenuation screen (sorter) test for tuned, angled single‑mode connectors.
• Required test apparatus: calibrated angled screen plug, optical source (specified wavelength), excitation fibre (minimum length), large‑area photodetector, and reference adaptor.
• Measurement method: insertion‑loss measurement protocol (consistent with IEC 61300 measurement practices) and specification of measurement sequence and averaging.
• Acceptance criteria: defined reference attenuation (A_ref) and maximum allowable attenuation (A_max) used to decide pass/fail during screening.
• Preconditioning and cleaning requirements for connectors and adaptors prior to measurement to ensure repeatable results.

Typical use and users

Used primarily by connector manufacturers for production screening and quality control, by independent test laboratories performing conformance or acceptance testing, and by engineering teams in manufacturers and network operators who need assurance that tuned angled connectors meet specified attenuation behaviour when mated randomly. Test engineers, QA managers, and product compliance specialists are common users of this procedure.

Related standards

Part of the IEC 61300 series (basic test and measurement procedures) and used alongside other parts that cover visual inspection, attenuation measurement methods, retention and mechanical tests, and connector interfaces (for example parts addressing visual inspection and insertion‑loss measurement). National and regional adoptions exist (EN/DIN national versions), which reproduce the IEC text for regional application.

FAQ

Q: What is this standard?

A: IEC 61300-2-40:2000 is an International Standard that specifies a screening test method for detecting unacceptable attenuation caused by tuning errors in single‑mode angled optical connectors with tuning mechanisms.

Q: What does it cover?

A: It covers the test arrangement, calibrated screen plug requirements, measurement equipment and sequence, preconditioning/cleaning, and the acceptance criteria (reference and maximum attenuation) used to screen connectors during production or acceptance testing.

Q: Who typically uses it?

A: Connector manufacturers (production and QA), independent test laboratories, and network equipment/test engineers who need to verify that tuned angled single‑mode connectors meet attenuation requirements when mated randomly.

Q: Is it current or superseded?

A: IEC 61300-2-40:2000 is a published IEC standard from 31 July 2000 and is listed in the IEC webstore as the base publication (edition 1.0).
