Splicing
Splicing is the practice of connecting two glass bres by fusing them so that they
cannot be taken apart.
A special arc splicing device is used. The bres, e.g. of the routing cables, are
combined at their ends with "pigtails". The splicing device adjusts the trims of
the glass bres perfectly to one another. With modern devices, the trimming is
fully automatic. The bres are then fused (welded) with an arc. Depending on the
quality of the splicing process, attenuation values of around 0.3 dB or with good
splicing values of even less than 0.02 dB can be attained. From experience, we
have attained an attenuation value of max. 0.1 dB with high-quality devices.
Splicing requires special equipment and the relevant experience.
Pigtail
Pre-assembled glass bre connection on which a FO connector has already
been mounted by the manufacturer
Used to connect optical components
Goal: to reduce plug assembly work on site
Advantages of pigtails
Low attenuation values and low-cost mechanical production
Consistently good quality, dened ferrule surface as no manual work (polishing
etc.) is needed
