Have you figured out why it can be so costly to install Fiber To The Home? Why Bell companies are reluctant to deploy fibers in metal tube production line directly to consumers inside a large scale?
It’s not the material cost. It’s the labor! The introduction of fiber into the subscriber loop has increased the installation of short cable lengths with large number of splices. The speed at which the cables can be placed, spliced, accessed and reconfigured are getting to be very important.
So the requirement for technologies that advertise to lessen the fiber deployment cost are incredibly high. Bell companies are anxious on acquiring these technologies and merchandise in order to reduce their cost and push the broadband fiber optic network installation.
That is certainly in which the high fiber count ribbon cables come to play. These compact, UV epoxy bonded cables consist with high precision optical fibers and might be massed fusion spliced with minimum loss. The products have proven to be an excellent platform for FTTH deployment.
Mass fusion splicing machines from Japanese companies certainly are a integrated thing about this process. These fusion splicers are utilized through the fiber installation technicians to splice approximately 24 fibers at any given time with extremely low splice loss.
The standard requirement of Optical fiber coloring machine is 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 easy mass fusion splicing and handling. And at the same, they must likewise be able to preserve the optical performance and mechanical reliability.
This means that ribbon fiber cables must pack high count of glass fibers, organize fibers precisely for mass fusion splicing, provide individual fiber identification, could be divided into single fibers or subunits, mechanically reliable and can be simply accessed through the end or midspan.
These requirements must all be met simultaneously making the manufacturing of top quality ribbon fibers a tricky task.
So fiber cable specialists concluded a excellent design. One coded array of fibers bonded within a line with fiber coating material. According to this fundamental structure, two designed emerged: edge bonded or encapsulated.
The edge bonded design basically bonds the fibers along with only materials somewhere between of each and every fiber. This design is more popular in the usa. 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 within a rectangular looking tube. This design are definitely more found in Japan.
Some time savings for Sheathing line are really big that sometimes inside the field individual fibers are ribbonlized to make mass fusion splicings.
However, the success of mass ribbon fiber splicing relies critically in the fiber geometry, the ribbon as well as the mass fusion splicer. Good quality and consistent mass fusion splices are only able to be manufactured with ribbons that are produced from fibers having stringent geometric tolerances.
Extremely high quality fibers and ribbons happen to be commercially available. And they have the fiber deployment in FTTH projects a joy to the installers.
