I recently watched my coworker disassembling a pc using only one tool. Was it the right tool for the job? Yes and no. It was the tool he had… it worked, however, there is definitely several tool out there that could have made the task easier! This example is certainly one that many fiber optic installers know all too well. As being a gentle reminder, how many of you have used your Splicer’s Tool Kit (cable knife/scissors) to get rid of jacketing or even slit a buffer tube and then make use of the scissors to hack away at the Kevlar? Did you nick the glass? Did you accidentally cut through the glass and have to start over?

Correctly splicing and terminating SZ stranding line requires special tools and methods. Training is very important and there are many excellent causes of training available. Do not mix your electrical tools together with your fiber tools. Use the right tool to do the job! Being proficient in fiber work can become increasingly necessary as the importance of data transmission speeds, fiber for the home and fiber towards the premise deployments continue to increase.

Many factors set fiber installations besides traditional electrical projects. Fiber optic glass is extremely fragile; it’s nominal outside diameter is 125um. The least scratch, mark or even speck of dirt will change the transmission of light, degrading the signal. Safety factors important since you will work with glass that may sliver into your skin without being seen through the human eye.

Transmission grade lasers are very dangerous, and require that protective eyewear is essential. This industry has primarily been coping with voice and data grade circuits that may tolerate some interruption or decrease of signal. Anyone speaking would repeat themselves, or perhaps the data would retransmit. Today we are dealing with IPTV signals and customers who can not tolerate pixelization, or momentary locking of the picture. All the situations mentioned are reason for the consumer to search for another carrier. Each situation could have been avoided if proper attention was provided to the methods used when preparing, installing, and looking after Fiber drawing machine.

With that in mind, why don’t we review basic fiber preparation? Jacket Strippers are utilized to eliminate the 1.6 – 3.0mm PVC outer jacket on simplex and duplex fiber cables. Serrated Kevlar Cutters will cut and trim the kevlar strength member directly underneath the jacket and Buffer Strippers will eliminate the acrylate (buffer) coating from your bare glass. A protective plastic coating is applied to the bare fiber following the drawing process, but just before spooling. The most typical coating is actually a UV-cured acrylate, which is applied in 2 layers, resulting in a nominal outside diameter of 250um for your coated fiber. The coating is highly engineered, providing protection against physical damage caused by environmental elements, such as temperature and humidity extremes, contact with chemicals, point of stress… etc. while minimizing optical loss.

Without this, the maker would struggle to spool the fiber without having to break it. The 250um-coated fiber is the building block for most common fiber optic cable constructions. It is usually used as is, specially when additional mechanical or environmental protection is not required, including on the inside of optical devices or splice closures. For extra physical protection and easy handling, a secondary coating of polyvinyl chloride (PVC) or Hytrel (a thermoplastic elastomer that has desirable characteristics to use as being a secondary buffer) is extruded within the 250um-coated fiber, improving the outside diameter up to 900um. This sort of construction is referred to as ‘tight buffered fiber’. Tight Buffered might be single or multi fiber and are seen in Premise Networks and indoor applications. Multi-fiber, tight-buffered cables often can be used as intra-building, risers, general building and plenum applications.

A ‘Rotary Tool’ or ‘Cable Slitter’ can be used to slit a ring around and thru the outer jacketing of ‘loose tube fiber’. As soon as you expose the durable inner buffer tube, use a ‘Universal Fiber Access Tool’ which is designed for single central buffer tube entry. Used on the same principle because the Mid Span Access Tool, (that allows access to the multicolored buffer coated tight buffered fibers) dual blades will slit the tube lengthwise, exposing the buffer coated fibers. Fiber handling tools like a spatula or even a lqzgij may help the installer to access the fiber in need of testing or repair.

After the damaged fiber is exposed a hand- stripping tool will be used to eliminate the 250um coating to be able to assist the bare fiber. The next phase will likely be cleansing the FTTH cable production line and preparing it to be cleaved. An excellent cleave is among the most significant factors of creating a low loss on the splice or a termination. A Fiber Optic Cleaver is actually a multipurpose tool that measures distance through the end of the buffer coating to the stage where it will likely be joined and it also precisely cuts the glass. Never forget to employ a fiber trash-can for the scraps of glass cleaved from the fiber cable.
