Are you aware why it really is so expensive to install Fiber To The Home? Why Bell companies are hesitant to deploy secondary coating line right to consumers within a large?
It’s not the fabric cost. It’s the labor! The roll-out of fiber in to the subscriber loop has grown the installation of short cable lengths with many splices. The speed in which the cables can be put, spliced, accessed and reconfigured are getting to be extremely important.
So the requirement for technologies that promise to minimize the fiber deployment cost are very high. Bell companies are anxious on acquiring these technologies and merchandise to be able to reduce their cost and push the broadband fiber optic network installation.
That is where the high fiber count ribbon cables visit play. These compact, UV epoxy bonded cables are comprised rich in precision optical fibers and might be massed fusion spliced with minimum loss. The products have proved to be a fantastic platform for FTTH deployment.
Mass fusion splicing machines from Japanese companies are a integrated thing about this process. These fusion splicers are utilized through the fiber installation technicians to splice as much as 24 fibers at one time with suprisingly low splice loss.
The standard necessity for optical fiber ribbon machine is usually to protect the glass fibers inside from harsh environment. But for ribbon fibers, there is the other vital requirement: organize the fibers for maximum space efficiency and ease of mass fusion splicing and handling. As well as at exactly the same, they must also be able to keep up 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 up into single fibers or subunits, mechanically reliable and can be easily accessed in the end or midspan.
These requirements must all be met simultaneously making the manufacturing of high quality ribbon fibers a tricky task.
So fiber cable specialists concluded a excellent design. A color coded variety of fibers bonded in a line with fiber coating material. Depending on this fundamental structure, two designed emerged: edge bonded or encapsulated.
The advantage bonded design basically bonds the fibers as well as only materials between of each and every fiber. This design is a lot 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 actually encapsulates all fibers in the rectangular looking tube. This design tend to be more used in Japan.
The time savings for FTTH drop cable production line are so big that sometimes inside the field individual fibers are ribbonlized to create mass fusion splicings.
However, the prosperity of mass ribbon fiber splicing relies critically on the fiber geometry, the ribbon as well as the mass fusion splicer. High quality and consistent mass fusion splices is only able to be produced with ribbons that are made from fibers having stringent geometric tolerances.
These high quality fibers and ribbons are actually commercially available. And so they have the fiber deployment in FTTH projects great for the installers.
