BS EN IEC 62074-1:2025 - TC

This standard BS EN IEC 62074-1:2025 - TC Tracked Changes. Fibre optic interconnecting devices and passive components. Fibre optic WDM devices is classified in these ICS categories:

• 33.180.01 Fibre optic systems in general
• 33.180.20 Fibre optic interconnecting devices

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.
