Optical fibre cables have seen widespread commercial use for broadband networks since the mid-2000s thanks to their superior bandwidth and speed over longer distances. Fibre has added data security, lower latency and – as anyone who still lives in an area not covered by full-fibre may know – optical fibre cables are less likely to be dug up and stolen for profit than their copper counterparts.

But these high-grade plastic, glass and silica cables that can transmit light signals with little loss of strength have been around much longer than the start of the new millennium. A theoretical description was published in 1961, by Elias Snitzer of American Optical, of single mode fibres with a core so small that it was able to carry light with only one wave-guide mode. The industry will also be more than familiar with the work of ‘father of fibre optics’ Charles Kao who discovered in the 1960s that, by carefully purifying glass, bundles of thin fibres could be manufactured that would be capable of carrying huge amounts of information over long distances with minimal signal attenuation. In 1970, a team of scientists at glass manufacturer Corning came up with a method of doping silica glass with titanium to make single mode fibres with attenuation of less than 20dB/km. 

The two main types of fibre used today are multimode and single-mode. Multimode fibre has a larger core so light can travel in many rays (or modes). It is mainly used for communication over shorter distances. Single-mode fibre has a much smaller core so light only travels in one mode. This is most commonly used in longer-distance transmissions, of more than 1km. There have also been a number of advances within these fibre types, such as ribbon cable and bend-insensitive fibre 

Ribbons have a number of conducting wires running in parallel to each other on the same flat plane, and were devised to combine a much-needed high fibre density with a simpler process for mass fusion termination process. The cable is pre-ribbonised, with groups of groups around 12 individual fibres that are bonded together for faster mass fusion splicing. This has the benefit of less time needing to be spent by installers.

Bend-insensitive fibre, meanwhile, was designed to overcome the problem of larger core fibre’s sensitivity when handling in terrestrial environments. If a fibre cable is bent excessively, the optical signal could refract and escape through the cladding. Bending can also cause damage to the fibre, resulting in bend loss. Bend-insensitive fibre has a layer of glass around the core of the fibre, which has a lower index of refraction. This means that it can essentially reflect the weakly guided modes back into the core when stress occurs.

Another relatively recent development is hollow core fibre, which uses gas or a vacuum in favour of traditional cores to enable properties such as faster light speed and reduced sensitivity to environmental variations.

With the FTTH market rapidly gaining pace, and many countries getting closer to achieving roll-out targets, it’s probably not surprising that the market for fibre optic cables is growing. A recent report from Market Reports World estimates the global market to be worth more than $12m this year, and forecasts a worth of more than $17m by 2028 with a compound annual growth rate of 6 per cent during the period.

Fibre coating removal: end and window strippers

Plasma work stations add a new level to stripping coatings, a unique fibre stripper/cleaner for polyimide, carbon and gold coated fibres. Ion etching removes coatings safely and cleanly from the fibre. The preparation unit, FPU II, provides a non-contact and chemical free window or end face stripping of polyimide and carbon coated optical fibres. The stripped region has tapered interfaces with no charring.

The AutoStrip II is designed for fast, chemical free window stripping of optical fibres, using patented Burst Technology and equipped with a built-in, high force, fibre tensile tester, which can pull the fibre up to 235kpsi (20N). Compact thermal strippers are alternative, easy-to-use fibre stripping units, designed to thermo-mechanically remove coatings from optical fibres, stripping extremely difficult and baked-on coatings and in some cases can even remove fluoroacrylate undercoatings. The use of chemicals for high strength fibre stripping is now a thing of the past! Find out more about the AutoStrip II by visiting the Laser Components website.
