Fiber Drawing Machine – Check Out This Article..

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 several tool out there that could have made the task easier! This case is unquestionably one that many fiber optic installers know all too well. As a gentle reminder, how many of you might have used your Splicer’s Tool Kit (cable knife/scissors) to remove 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 Fiber coloring machine requires special tools and techniques. Training is very important and there are many excellent sources of training available. Do not mix your electrical tools along with your fiber tools. Utilize the right tool for the task! Being proficient in fiber work will end up increasingly necessary as the value of data transmission speeds, fiber for the home and fiber towards the premise deployments continue to increase.

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

Transmission grade lasers are incredibly dangerous, and require that protective eyewear is essential. This industry has primarily been coping with voice and data grade circuits which could tolerate some interruption or decelerate of signal. The individual speaking would repeat themselves, or perhaps the data would retransmit. Today our company is coping with IPTV signals and customers who can not tolerate pixelization, or momentary locking from the picture. All the situations mentioned are cause of the client to look for another carrier. Each situation might have been avoided if proper attention was given to the strategies used in planning, installing, and looking after FTTH cable production line.

Having said that, why don’t we review basic fiber preparation? Jacket Strippers are employed to remove 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 remove the acrylate (buffer) coating from your bare glass. A protective plastic coating is used to the bare fiber following the drawing process, but prior to spooling. The most typical coating is a UV-cured acrylate, which can be applied in two layers, resulting in a nominal outside diameter of 250um for the coated fiber. The coating is extremely engineered, providing protection against physical damage due to environmental elements, including temperature and humidity extremes, exposure to chemicals, reason for stress… etc. while minimizing optical loss.

Without this, the manufacturer would not be able to spool the fiber without breaking it. The 250um-coated fiber is the foundation for many common fiber optic cable constructions. It is usually used as it is, specially when additional mechanical or environmental protection is not needed, like inside of optical devices or splice closures. For additional physical protection and easy handling, a secondary coating of polyvinyl chloride (PVC) or Hytrel (a thermoplastic elastomer which has desirable characteristics to use as being a secondary buffer) is extruded over the 250um-coated fiber, increasing the outside diameter up to 900um. This type of construction is known as ‘tight buffered fiber’. Tight Buffered might be single or multi fiber and therefore are seen 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’ can 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 since the Mid Span Access Tool, (that enables access to the multicolored buffer coated tight buffered fibers) dual blades will slit the tube lengthwise, exposing the buffer coated fibers. Fiber handling tools for instance a spatula or even a lqzgij can help the installer to gain access to the fiber needing testing or repair.

Once the damaged fiber is exposed a hand- stripping tool will be used to remove the 250um coating to be able to work together with the bare fiber. The next step will be cleaning the Secondary coating line and preparing it to be cleaved. A good cleave is one of the most important factors of creating a low loss on a splice or even a termination. A Fiber Optic Cleaver is actually a multipurpose tool that measures distance from the end in the buffer coating to the point where it will likely be joined plus it precisely cuts the glass. Always remember to utilize a fiber trash-can for the scraps of glass cleaved off the fiber cable.
