What is BS EN IEC 61300‑3‑30 about?
BS EN IEC 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 IEC 61300‑3‑30 describes a method of measuring the end face geometry of rectangular multifibre ferrules having an IEC defined optical interface. The primary attributes are fibre position relative to the end face, either withdrawal or protrusion, end face angle relative to the guide pin bores, fibre tip radii and core dip for multimode fibres.
BS EN IEC 61300‑3‑30 also provides information about guide pin based multifibre connector plugs which typically have a rectangular end face with a long axis and a short axis. Ideally, a flat polish is desired on the end face with the fibres protruding slightly and all in the same plane to assure physical contact of the fibre cores when two connectors are intermated.
The apparatus specified in BS EN IEC 61300‑3‑30 consists of a positioning stage, a ferrule holder, an interferometric video microscope, a Personal Computer-based fringe interpretation unit and a monitor to view the ferrule end face interferogram and display the analysis results.
Who is BS EN IEC 61300‑3‑30 for?
BS EN IEC 61300‑3‑30 on fibre optic interconnecting devices and passive components is useful for:
- Telecommunication equipment and components manufacturers
- Design engineer
- Research and development facilities
- Quality control personnel
Why should you use BS EN IEC 61300‑3‑30?
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. BS EN IEC 61300‑3‑30 focuses on fibre-optic interconnection devices and passive components and provides you guidance on each optical fibre component and its functional applications by applying measurement and examination methods.
BS EN IEC 61300‑3‑30 specifies the ferrule holder that states that is a suitable device to hold the ferrule in a fixed position, either vertical or horizontal, or in a tilted position in the case of an angled ferrule type and this method is used to determine the axis of each guide hole and the average plane perpendicular to the guide hole axes.
The test procedure mentioned in BS EN IEC 61300‑3‑30 gives specification on the end face geometry of rectangular ferrule and its measurement and examination as the end face of ferrules are domed to ensure that the contact area between mating connectors is at the centre of the ferrule where the fibre core will be located. 
The end face geometry of a PC polished connector which is described in BS EN IEC 61300‑3‑30 on fibre optic interconnecting devices and passive components has been known to play an important role in the long-term performance of a single-mode connection. Using BS EN IEC 61300‑3‑30 you can specify the primary function of the PC polish design and understand the method of measuring the end face geometry of rectangular multifibre ferrules having an IEC defined optical interface.
