Have you figured out why it is actually so costly to install Fiber Towards The Home? Why Bell companies are unwilling to deploy SZ stranding line instantly to consumers within a massive?
It’s not the content cost. It’s the labor! The creation of fiber in the subscriber loop has grown installing short cable lengths with great number of splices. The pace in which the cables can be placed, spliced, accessed and reconfigured have grown to be vitally important.
So the demand for new technologies which promise to reduce the fiber deployment cost are extremely high. Bell companies are anxious on acquiring these technologies and products so that you can reduce their cost and push the broadband fiber optic network installation.
That is in which the high fiber count ribbon cables visit play. These compact, UV epoxy bonded cables are comprised with high precision optical fibers and can be massed fusion spliced with minimum loss. These items have proved to be a great platform for FTTH deployment.
Mass fusion splicing machines from Japanese companies are a integrated part of this process. These fusion splicers are used through the fiber installation technicians to splice around 24 fibers at a time with suprisingly low splice loss.
The most basic requirement of Optic fiber draw tower is always to protect the glass fibers inside from harsh environment. But for ribbon fibers, you have the other vital requirement: organize the fibers for optimum space efficiency and easy mass fusion splicing and handling. And also at exactly the same, they should likewise be able to preserve the optical performance and mechanical reliability.
Consequently ribbon fiber cables must pack high count of glass fibers, organize fibers precisely for mass fusion splicing, provide individual fiber identification, might be split into single fibers or subunits, mechanically reliable and can be accessed from your end or midspan.
These requirements must be met simultaneously making the manufacturing of top quality ribbon fibers a difficult task.
So fiber cable specialists concluded a excellent design. A color coded variety of fibers bonded within a line with fiber coating material. According to this fundamental structure, two designed emerged: edge bonded or encapsulated.
The advantage bonded design basically bonds the fibers along with only materials between of each and every fiber. This design is far more popular in the states. This design is 40% smaller szzstrand the encapsulated design.
In encapsulate design, bonding materials extend well beyond the gaps between fibers, it really encapsulates all fibers in the rectangular looking tube. This design are definitely more employed in Japan.
Time savings for FFTH cable production line are so big that sometimes within the field individual fibers are ribbonlized to help make mass fusion splicings.
However, the achievements mass ribbon fiber splicing relies critically on the fiber geometry, the ribbon as well as the mass fusion splicer. Premium quality and consistent mass fusion splices are only able to be produced with ribbons that are made from fibers having stringent geometric tolerances.
These high quality fibers and ribbons already are commercially available. And so they create the fiber deployment in FTTH projects a joy for the installers.
