What is BS EN 61300-3-35 - Fibre optic interconnecting devices and passive components about?
BS EN 61300 is a series on fibre optic interconnecting devices and passive components. Fibre optic interconnecting devices and passive components is a fibre optic telecommunications technology for delivering broadband network access to end customers. BS EN 61300-3-35 describes methods for quantitatively assessing the end face quality of a polished fibre optic connector or of a fibre optic transceiver using a fibre-stub type interface. Sub-surface cracks and fractures are not considered in BS EN 61300-3-35. In general, the methods described in BS EN 61300-3-35 apply to 125 μm cladding fibres contained within a ferrule and intended for use with sources of ≤ 2 W of input power. However, portions are applicable to non-ferruled connectors and other fibre types. Those portions are identified where appropriate. It is not the intention of BS EN 61300-3-35 that the size of scratches should be measured, the dimensions and requirements are selected such that they can be estimated. There is no need to measure for example if a scratch is 2,3 μm wide.
Who is BS EN 61300-3-35 - Fibre optic interconnecting devices and passive components for?
BS EN 61300-3-35 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 61300-3-35 - Fibre optic interconnecting devices and passive components?
Fibre optic interconnecting devices and passive components architecture implements a point-to-multipoint topology in which a single optical fibre serves multiple endpoints by using an unpowered (passive) fibre optic splitter to divide the fibre bandwidth among the endpoints. The objective of BS EN 61300-3-35 is to prescribe methods for quantitatively inspecting fibre optic end faces to determine if they are suitable for use. Three methods are described which are direct view optical microscopy, video microscopy and automated analysis microscopy.
Within each method, there are hardware requirements and procedures for both low resolution and high-resolution systems. Low-resolution systems should be used for the examination of single-mode and multi-mode connectors prior to mating and after polishing. High-resolution systems may be used for end-face inspection in the factory after polishing of single-mode connectors. High-resolution systems are not required for inspection in the field nor for inspection of multi-mode connectors or for field polished connectors. For Methods A and B, it is recommended that visual gauge tools be developed to facilitate the measurement procedure. For Method A, an eyepiece reticule is recommended. For Method B, an overlay is recommended. All methods are susceptible to system variability. Methods A and B are operator dependent; Method C is operator independent. Using BS EN 61300-3-35 you can describe methods for quantitatively assessing the end face quality of a polished fibre optic connector or of a fibre optic transceiver using a fibre-stub type interface.
