New Release Comsof Fiber version 21.1

Version 21.1 of Comsof Fiber sees some great new features and tweaks to help make your design experience more intuitive and smooth. There are new rules for splicing and bundling cables, and reusing cables for Ring Design. We have also made it possible to configure rules via the web UI. There are a whole bunch of others changes that you can read about in this post.

Fiber Connectivity

We have made the order of fibers more logical and the connectivity consistent at splice locations. There are also extra options available to control the splicing logic in the design. The options are listed below.

Splice unused fibers in a bundle. If fibers in a bundle are activated then all fibers in that bundle will be spliced. This rule can be configured between layers or within a layer.
E.g. A cable with 2 bundles of 4 fibers. If 2 fibers of the 1st bundle need to be activated. Then the 2 other fibers of that bundle will be spliced. The 4 fibers of the other bundle will not be spliced.

Following options are available for the shared cable strategies:

  • Bundle stacking. This is an alternative option for “assign a complete bundle” when sharing a cable between different aggregation points. When the bundle stacking option is enabled then an aggregation point will take fibers from a single fiber bundle, but it is possible to serve different points from the same bundle. This option is also available for the ring strategy
    E.g. A shared cable that serves 3 points that each requires 3 fibers.

Comsof Fiber 21.1

There are 3 options to use the fibers in the cable: stack bundles, share bundles or assign a complete bundle per point. Below you can see how the fibers would be assigned for the example above.

Assignment order on shared cable. It is possible to choose to serve the first points on a shared cable with the first fibers and bundles or serve the last points with the first fibers and bundles.

Window cut. Three options are available when splicing on a shared cable:

  • Cut the complete cable: The whole cable is cut at a splice location

  • Window cut (bundle): the bundle that contains fibers that need to be spliced at the splice location is cut. If the bundle contains fibers that serve points further in the network, then these fibers are spliced.

  • Window cut (fiber): only the fibers that need to be spliced at the splice location are cut.

Example: A shared cable where all fibers are active. At a splice location 2 fibers are branched off. Depending on the window cut configuration all fibers, only the fibers needed at the splice location or the fibers in the bundle are cut and spliced.

Reuse existing cables for Ring designs

The “auto ring” and “manual drawn ring” strategy now support the reuse of existing cables. The capacity on the existing cables will also be respected.

Existing cables could already be loaded since version 2019.2 and in version 2019.4 we added support for the shared cable strategy.

Web-UI

It is now possible to configure the rules via a web interface. The rules are still edited on your system but are opened in your local browser.

We use a newer and more flexible technology for this interface which allows us to modernize and make the rules configuration more user-friendly in the future. In one of the following versions the old rules editor will be replaced completely by this interface.

Increased performance and more efficient memory usage

We have made some structural changes in the build process of the software. This results in a faster start-up time of the software (e.g. when opening the rules), faster pre-processing and calculation times, and more efficient memory usage. In our benchmark testing, the calculation times reduced between 15 and 50%.

More detailed output

We have added extra information in the output for the design mode:

  • Fibers and splices. Extra details on the active fibers and the splices is now available.

  • Microduct connectors. The locations where 2 microducts need to be connected are now available in the GIS output. For each connector you know which index of the ducts need to be connected.

  • Cable slack location. An attribute that links to the location of the cable slack in the network was added.

Automatic labelling

We’ve added a mechanism to automatically generate labels for the equipment in the design mode.

Following elements can get a label based on a configurable label rule: Aggregation point, access structures, closures, cables, ducts, splitters and splices. The rule can be configured per layer.

At the moment, this functionality cannot be configured by a user. But if you are interested please contact your account manager.
