Have you figured out why it is so expensive to install Fiber For The Home? Why Bell companies are hesitant to deploy Sheathing line right to consumers in a large?
It’s not the material cost. It’s the labor! The development of fiber into the subscriber loop has grown setting up short cable lengths with large number of splices. The speed at which the cables may be placed, spliced, accessed and reconfigured have grown to be extremely important.
So the necessity for new technologies that promise to lower the fiber deployment cost are incredibly 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.
Which 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 might be massed fusion spliced with minimum loss. These products have proved to be an outstanding platform for FTTH deployment.
Mass fusion splicing machines from Japanese companies can be a integrated point about this process. These fusion splicers are used with the fiber installation technicians to splice up to 24 fibers at any given time with suprisingly low splice loss.
The most basic requirement of Sheathing line is always to protect the glass fibers inside from harsh environment. But for ribbon fibers, there is the other vital requirement: organize the fibers for optimum space efficiency and ease of mass fusion splicing and handling. As well as at the identical, they must also be able to maintain the optical performance and mechanical reliability.
Because of this ribbon fiber cables must pack high count of glass fibers, organize fibers precisely for mass fusion splicing, provide individual fiber identification, can be separated into single fibers or subunits, mechanically reliable and can be easily accessed from your end or midspan.
These requirements must all be met at the same time that makes the manufacturing of top quality ribbon fibers a tough task.
So fiber cable specialists concluded a excellent design. A color coded selection 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 together with only materials in between of each fiber. This design is a lot more popular in the United States. 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 inside a rectangular looking tube. This design are definitely more employed in Japan.
The time savings for secondary coating line are so big that sometimes within the field individual fibers are ribbonlized to create mass fusion splicings.
However, the achievements of mass ribbon fiber splicing relies critically around the fiber geometry, the ribbon along with the mass fusion splicer. Premium quality and consistent mass fusion splices is only able to be manufactured with ribbons that are made from fibers having stringent geometric tolerances.
These high quality fibers and ribbons are already commercially available. And they also make the fiber deployment in FTTH projects fantastic to the installers.
