The simple fibre assembly system

In the growing fibre-optics market, the times that installation crews are allowed for performing their jobs are becoming ever-shorter while the quality standards are still expected to meet the network requirements. Huber+Suhner's quick-assembly system combines proven FSC and FST connector technology with a modern and time-saving field assembly process.

The installation of fibre-optic cables is characterised by cable laying and splicing, both of which are time and labour-consuming. Huber+Suhner's quick-assembly system, called the Manipulator, can reduce assembly times to 1,5 minutes. The system has been designed to allow the process to be performed in a controlled way with just a few manipulations.

With this tool there is no need to crimp the connector, and lapping can be done without the support of fixed surfaces. All accessories can be conveniently carried in a person's pocket. The need for a microscope is eliminated by the visual polishing checking feature using colour markings.

The Manipulator hand tool is provided with an internal power supply and can be used across a wide temperature range.

In the quick-assembly process, the ferrule is glued. This prevents floating of the fibre in the ferrule so that consistent values are obtained. The adhesive in the Manipulator is premixed and stored in a patented powder form in an integrated container. The quick-assembly system prevents any incorrect doses of glue by ensuring that only the fibre and not the buffer is glued. The buffer is also not clamped by mechanical pressure which might affect the fibre, but by using clips provided with barbs. This avoids detrimental effects on the fibre.

In realistic installation environments, lighting is not always what it ought to be. This makes scoring of the transparent fibre difficult. The quick-assembly system avoids this difficulty by ensuring reliable fibre breaking using entirely internal ceramic scoring. This process guarantees identical and repeatable conditions for the lapping process. Thanks to the elimination of any mechanical splice, system reliability is enhanced. For disposal, installation crews stick hazardous fibre remainders onto a piece of adhesive film. This risk is eliminated in the Manipulator by automatic disposal during fibre-breaking. The fibre remainder is transferred to an integrated container, which can be disposed of as a whole.

With this quick-assembly system, Suhner Fiberoptic offers a process based on tried-and-tested SC and ST connector technology which can be used in field assembly applications.
