Recently i watched my coworker disassembling a personal computer 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 exists definitely multiple tool out there that could have made the task easier! This case is definitely one that many fiber optic installers know all too well. As being a gentle reminder, what percentage of you have used your Splicer’s Tool Kit (cable knife/scissors) to remove jacketing or even slit a buffer tube and then utilize the scissors to hack away at the Kevlar? Did you nick the glass? Did you accidentally cut through the glass and need to start over?

Correctly splicing and terminating optical fiber ribbon machine requires special tools and methods. Training is important and there are numerous excellent types of training available. Tend not to mix your electrical tools along with your fiber tools. Use the right tool to do the job! Being familiar with fiber work will end up increasingly necessary as the value of data transmission speeds, fiber towards the home and fiber to the premise deployments continue to increase.

Many factors set fiber installations aside from traditional electrical projects. Fiber optic glass is extremely fragile; it’s nominal outside diameter is 125um. The slightest scratch, mark or even speck of dirt will impact the transmission of light, degrading the signal. Safety factors are important because you are working with glass that will sliver in your skin without being seen from the eye.

Transmission grade lasers are incredibly dangerous, and require that protective eyewear is important. This industry has primarily been working with voice and data grade circuits that could tolerate some interruption or decelerate of signal. The individual speaking would repeat themselves, or the data would retransmit. Today we are working with IPTV signals and customers that will not tolerate pixelization, or momentary locking of the picture. Each of the situations mentioned are cause for the customer to find another carrier. Each situation might have been avoided if proper attention was given to the techniques used when preparing, installing, and looking after SZ stranding line.

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 beneath the jacket and Buffer Strippers will take away the acrylate (buffer) coating from the bare glass. A protective plastic coating is applied for the bare fiber following the drawing process, but just before spooling. The most frequent coating is a UV-cured acrylate, that 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 due to environmental elements, like temperature and humidity extremes, exposure to chemicals, reason for stress… etc. while also minimizing optical loss.

Without one, the maker would be unable to spool the fiber without having to break it. The 250um-coated fiber is definitely the building block for most common fiber optic cable constructions. It is usually used as is, particularly when additional mechanical or environmental protection is not needed, like within optical devices or splice closures. For further physical protection and ease of handling, a secondary coating of polyvinyl chloride (PVC) or Hytrel (a thermoplastic elastomer which includes desirable characteristics to be used as being a secondary buffer) is extruded over the 250um-coated fiber, increasing the outside diameter approximately 900um. This kind of construction is known as ‘tight buffered fiber’. Tight Buffered may be single or multi fiber and they are noticed in Premise Networks and indoor applications. Multi-fiber, tight-buffered cables often are used for intra-building, risers, general building and plenum applications.

A ‘Rotary Tool’ or ‘Cable Slitter’ may be used to slit a ring around and through the outer jacketing of ‘loose tube fiber’. When you expose the durable inner buffer tube, use a ‘Universal Fiber Access Tool’ which is perfect for single central buffer tube entry. Used on the same principle as the Mid Span Access Tool, (which 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 a lqzgij can help the installer to access the fiber looking for testing or repair.

After the damaged fiber is exposed a hand- stripping tool will be used to remove the 250um coating to be able to work with the bare fiber. The next step is going to be washing the optical fiber coloring machine and preparing it to be cleaved. An excellent cleave is probably the most essential factors of producing a low loss over a splice or even a termination. A Fiber Optic Cleaver is a multipurpose tool that measures distance from your end of the buffer coating to the level where it will probably be joined and it also precisely cuts the glass. Remember to utilize a fiber trash-can for that scraps of glass cleaved off the fiber cable.
