Have you figured out why it is actually so expensive to install Fiber Towards The Home? Why Bell companies are reluctant to deploy fibers in metal tube production line right to consumers in the massive?
It’s not the content cost. It’s the labor! The development of fiber in the subscriber loop has risen the installation of short cable lengths with many splices. The pace at which the cables may be put, spliced, accessed and reconfigured have grown to be essential.
So the need for technologies that advertise to minimize the fiber deployment cost are really high. Bell companies are anxious on acquiring these technologies and products to be able to reduce their cost and push the broadband fiber optic network installation.
Which is the location where the high fiber count ribbon cables visit play. These compact, UV epoxy bonded cables are comprised with good precision optical fibers and can be massed fusion spliced with minimum loss. These products have shown to be an excellent platform for FTTH deployment.
Mass fusion splicing machines from Japanese companies can be a integrated part of this process. These fusion splicers are being used through the fiber installation technicians to splice around 24 fibers at one time with very low splice loss.
The standard need for FTTH cable production line is usually to protect the glass fibers inside from harsh environment. However, for ribbon fibers, you have the other vital requirement: organize the fibers for optimum space efficiency and comfort of mass fusion splicing and handling. As well as at the same, they have to also be able to maintain the optical performance and mechanical reliability.
Which means that ribbon fiber cables must pack high count of glass fibers, organize fibers precisely for mass fusion splicing, provide individual fiber identification, may be split into single fibers or subunits, mechanically reliable and can be accessed through the end or midspan.
These requirements must be met as well making the manufacturing of top quality ribbon fibers a tough task.
So fiber cable specialists concluded a excellent design. One coded array of fibers bonded in a line with fiber coating material. Based on this fundamental structure, two designed emerged: edge bonded or encapsulated.
The advantage bonded design basically bonds the fibers combined with only materials somewhere between for each fiber. This design is a lot more popular in the usa. This design is 40% smaller szzstrand the encapsulated design.
In encapsulate design, bonding materials extend well past the gaps between fibers, it really encapsulates all fibers within a rectangular looking tube. This design are more used in Japan.
Enough time savings for secondary coating line are incredibly big that sometimes in the field individual fibers are ribbonlized to produce mass fusion splicings.
However, the success of mass ribbon fiber splicing relies critically on the fiber geometry, the ribbon as well as the mass fusion splicer. Good quality and consistent mass fusion splices are only able to be produced with ribbons that are produced from fibers having stringent geometric tolerances.
These high quality fibers and ribbons happen to be commercially available. And so they create the fiber deployment in FTTH projects fantastic for that installers.
