What is BS EN 61300-2-43 - 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 61300-2-43 aims at screening single-mode physical contact (PC) optical fibre connectors of an optical fibre cord or an optical fibre pigtail in terms of return loss, thus ensuring minimum return loss when the connectors, which have been screen-tested by this method, are randomly mated with each other in the field.
Who is BS EN 61300-2-43 - Fibre optic interconnecting devices and passive components for?
BS EN 61300-2-43 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 61300-2-43 - Fibre optic interconnecting devices and passive components?
Fibre optic interconnecting devices and passive components architecture implement a point-to-multipoint topology in which a single optical fibre serves multiple endpoints by using unpowered (passive) fibre optic splitters to divide the fibre bandwidth among the endpoints. The domed ferrule end faces of PC connectors (not angled) are produced by a polishing process. This polishing process results in a thin damaged layer at the fibre end face of the connector. In silica fibres, the refractive index of the damaged layer is slightly higher than that of the original fibre. This high refractive index layer generates optical reflection. When PC connectors are mated, return loss occurs as a result of multiple reflections at the two damaged layers of the butted connectors.
The test procedures as described in BS EN 61300-2-43 ensures that a designed minimum return loss is achieved when PC connectors are randomly mated. It screens cords or pigtails by using a pair of reflection standard plug (RP) cords. The pair of reflection standard plugs are selected on the condition that the return loss when the plugs are mated is several decibels better than the designed minimum return loss. Cords that pass this test will achieve the designed minimum return loss in over 99 % of cases when randomly mated.
Using BS EN 61300-2-43 you can specify screening single-mode physical contact (PC) optical fibre connectors of an optical fibre cord or an optical fibre pigtail.
