DIN EN IEC 62074-1 VDE 0885-600:2026-04

This part of IEC 62074 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 the entry and/or exit of optical power, 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.
