Recently i 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 multiple tool out there that would have made the task easier! This example is definitely one that many fiber optic installers know all too well. As being a gentle reminder, what number 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 optical fiber ribbon machine requires special tools and methods. Training is important and there are lots of excellent causes of training available. Tend not to mix your electrical tools along with your fiber tools. Make use of the right tool for the task! Being proficient in fiber work will end up increasingly necessary as the significance of data transmission speeds, fiber towards the home and fiber to the premise deployments still increase.

Many factors set fiber installations apart from traditional electrical projects. Fiber optic glass is very 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 is important because you will work with glass that can sliver to your skin without getting seen through the human eye.

Transmission grade lasers are very dangerous, and require that protective eyewear is essential. This industry has primarily been dealing with voice and data grade circuits that may tolerate some interruption or slow down of signal. The person speaking would repeat themselves, or perhaps the data would retransmit. Today our company is dealing with IPTV signals and customers who can not tolerate pixelization, or momentary locking from the picture. Each of the situations mentioned are cause of the customer 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 SZ stranding line.

With that in mind, 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 for the bare fiber following the drawing process, but just before spooling. The most common coating is really a UV-cured acrylate, which is applied in two layers, resulting in a nominal outside diameter of 250um for that coated fiber. The coating is extremely engineered, providing protection against physical damage caused by environmental elements, including temperature and humidity extremes, exposure to chemicals, point of stress… etc. while minimizing optical loss.

Without one, the manufacturer would not be able to spool the fiber without having to break it. The 250um-coated fiber is definitely the building block for many common fiber optic cable constructions. It is often used as it is, specially when additional mechanical or environmental protection is not needed, 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 which has desirable characteristics to be used being a secondary buffer) is extruded within the 250um-coated fiber, increasing the outside diameter approximately 900um. This type of construction is called ‘tight buffered fiber’. Tight Buffered may be single or multi fiber and are noticed in Premise Networks and indoor applications. Multi-fiber, tight-buffered cables often can be used for intra-building, risers, general building and plenum applications.

A ‘Rotary Tool’ or ‘Cable Slitter’ could be used to slit a ring around and through the outer jacketing of ‘loose tube fiber’. As soon as you expose the durable inner buffer tube, you can use a ‘Universal Fiber Access Tool’ which is designed for single central buffer tube entry. Used on the same principle since 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 such as a spatula or a lqzgij can help the installer to get into the fiber needing testing or repair.

Once the damaged fiber is exposed a hand- stripping tool will be employed to take away the 250um coating in order to work with the bare fiber. The next step is going to be washing the optical fiber ribbon machine and preparing that it is cleaved. A great cleave is probably the most significant factors of making a low loss on a splice or perhaps a termination. A Fiber Optic Cleaver is actually a multipurpose tool that measures distance through the end in the buffer coating to the stage where it will be joined plus it precisely cuts the glass. Remember to utilize a fiber trash-can for the scraps of glass cleaved off the fiber cable.
