DIN EN 62074-1:2010-07

This part of IEC 62074 applies to fibre optic wavelength division multiplexing (WDM) devices. They have the following general features: - they are passive, that means, that they contain no optoelectronic or other transducing elements; but they may use temperature control only the purpose to stabilize the characteristics of devices; they exclude any optical switching function; - 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 standard establishes uniform requirements for the optical, mechanical and environmental properties. The responsible Committee is Subcommittee UK 412.7 "LWL-Verbindungstechnik und passive optische Komponenten" ("Fibre optic interconnecting devices and passive optical components") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
