What is BS EN 62074-1 - Fibre optic interconnecting devices and passive components about?
BS EN 62074 is a series on fibre optic interconnecting devices and passive components. Fibre optic interconnecting devices and passive components ensure an optical function necessary for the proper functioning of the network. BS EN 62074-1 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 may 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
BS EN 62074-1 establishes uniform requirements for the following:
- Optical, mechanical, and environmental properties
Who is BS EN 62074-1 - Fibre optic interconnecting devices and passive components for?
BS EN 62074-1 on fibre optic interconnecting devices and passive components is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 62074-1 - Fibre optic interconnecting devices and passive components?
Fibre optic interconnecting devices and passive components do not require external energy input because they operate on the optical signal. BS EN 62074-1 defines fibre optic wavelength division multiplexing devices that are classified into type, style, variant, environmental category, assessment level and extensions. Performance standards as described in BS EN 62074-1 contain a series of sets of tests and measurements (which may or may not be grouped into a specified schedule depending on the requirements of that standard) with clearly defined conditions, severities, and pass/fail criteria. The tests are intended to be run on a “once-off” basis to prove any product’s ability to satisfy the “performance standards” requirement. Each performance standard has a different set of tests, and or severities (and or groupings) represent the requirements of a market sector, user group or system location.
Reliability standards as described in BS EN 62074-1 are intended to ensure that a component can meet performance specifications under stated conditions for a stated time period. For each type of component needs are identified which are failure modes (observable general mechanical or optical effects of failure), failure mechanisms (general causes of failure, common to several components), and failure effects (detailed causes of failure, specific to component). These are all related to environmental and material aspects. Initially, immediately after component manufacture, there is an “infant mortality phase” during which many components would fail if they were deployed in the field. To avoid early field failure, all components may be subjected to a screening process in the factory, involving environmental stresses that may be mechanical, thermal and humidity related. This is to induce known failure mechanisms in a controlled environmental situation to occur earlier than would normally be seen in the unscreened population. For those components that survive (and are then sold), there is a reduced failure rate since these mechanisms have been eliminated. Using BS EN 62074-1 you can specify fibre optic wavelength division multiplexing devices.
