Fibre optic interconnecting devices and passive components - Fibre optic WDM devices - Part 1: Generic specification

Scope

IEC 62074-1: 2025 applies to fibre optic wavelength division multiplexing (WDM) devices. These have all of the following general features:

- they are passive, in that they contain no optoelectronic or other transducing elements; however they can use temperature control only to stabilize the device characteristics; they exclude any optical switching functions;

- they have three or more ports for either the entry or exit of optical power, or both, and share optical power among these ports in a predetermined fashion depending on the wavelength;

- the ports are optical fibres, or optical fibre connectors.

This document establishes uniform requirements for the following:

- optical, mechanical and environmental properties.

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 changes with respect to the previous edition:

a) harmonization of terms and definitions with IEC TS 62627-09;

b) simplified classification, documentation and standardization system in Clause 4, and moving interface style to Annex H.
