An Integrated Mapping Approach – What is typical with many fiber optic engineering projects is thatroutes are planned in one environment (consumer GIS or paper maps), with construction and permitdrawings created from scratch in another environment such as CAD, then this data is re‐encoded into aGIS based mapping system for on‐going facility management. When utilized throughout all the phases ofa project, NexusWorx can be the central software in a seamless process from planning to as‐built facilitymanagement. In this manner a project starts with intelligent digital mapping that is used throughout allthe other processes, not as disconnected tools in different environments.NexusWorx provides an excellent environment to seamlessly plan, design, engineer and manage yourfiber optic network facilities regardless of the different types of project team members and theirdifferent functions. The use of NexusWorx throughout these stages are identified below:Planning –The first phase of planning utilizes NexusWorx’s seamless mapping environment to definethe desired paths for the various fiber routes. In some cases the route planning could be dependent ongeospatial information such as existing structure data from 3rd party utility owners. Most utility andtelecommunications companies maintain their outside plant structure data in geospatial systems eitherin GIS or CAD platforms. NexusWorx provides an environment for loading this geo‐referenced data forthis planning function.With these routes identified, the process of identifying and negotiating with support structure facilitiesowners would commence. Routes can also be detailed in NexusWorx through it’s inherit integrationwith Google Earth where routes can be defined within Google Earth and then loaded into NexusWorx.An additional method of data loading is the use of geocoding. NexusWorx supports address andintersection geocoding (pinpointing a latitude/longitude point based on interactive or batch modeinputs allowing the NexusWorx user to visualize multiple locations based on these values.As the routes are finalized the cable locations, construction types, sizes, splice locations can be definedcreating another level of detail in the system. In addition, connectivity at the strand and port level canbe built during this phase identifying which fiber paths will be allocated or utilized at which location orarea. Once the plan is reviewed and approved with related joint‐use agreements executed, the detailedengineering phase can commence. It is most likely that detailed engineering will occur, prior to an entireplanning phase being fully completed, as with many middle mile type projects they can have multiplegeographical phases., provided that agreements have been executed and routes approved.

Detailed view of facilities mapped in NexusWorxEngineering (Construction Drawings) – An integrated engineering process with NexusWorx willincorporate the collection and loading of field note data, such as aerial make‐ready, duct assignmentand new route GPS data into NexusWorx. While NexusWorx is not a CAD system, this data can becollected and loaded into NexusWorx for making design decisions, and then exporting these graphics toMicrosoft Visio where construction graphics, details and notes can be added for the creation ofconstruction drawings or this data can export to other CAD systems such as Microstation or AutoCAD forthe same purpose. This process eliminates the redundant drawing of primary features such as; fiber,splice cases, structures (conduit, manholes and poles) and utilizes the graphics and text as displayed inNexusWorx. In addition to the primary construction drawings other detailed drawings required such asmanhole laydowns, splice diagrams and governmental permits could be created in the CAD enviroment.As part of this phase, physical connectivity (cable counts) can be finalized. This will allow reports to begenerated in spreadsheets for each splice closure showing how strands are connected at each spliceclosure location.

Example of NexusWorx‐Visio Construction DrawingConstruction & As‐built – During the construction management and as‐built phase, the constructionactivities and states will be maintained in NexusWorx. For example a cable segment’s project and reelattributes can be tracked including whether the reel is ordered or on‐site; and cable construction statesuch as planned, scheduled, underway, roadblock or completed. As segments progress through thesestates, the cable data can be updated via a map or data only interface which provides users a thematicmap view of fiber cable segments by the various status. All as‐built adjustments to the engineeredroutes will be denoted on either red‐lined construction drawings prints and updated in NexusWorx orloaded directly into NexusWorx through GPS point data and notes. For routes that are not on/in joint‐use structures, sub‐meter GPS shots can be taken for precise mapping of the fiber cable route (meaningits structures) then this data can be loaded directly into NexusWorx. Once loaded into NexusWorx thestructures and cables can be easily adjusted to these locations.As splice acceptance loss data is captured for various splices, this data can be captured into a splicespreadsheet for easy systematic loading into NexusWorx. (Please do note that standard default spliceand strand loss values are automatically entered into NexusWorx, providing a framework for lossmanagement. When actual data entered it is utilized in replace of default values for more precise spanloss calculation)As a result of capturing all of the data items mentioned above during the construction phase,NexusWorx becomes a web‐based map interface for quickly ascertaining construction project status andissues from a geospatial perspective.

Fiber Management (Mapping) – Once construction is closed out and as‐built data loaded or encodedinto NexusWorx, the end result of utilizing this seamless process is that all fiber network data is nowwithin the NexusWorx system for management moving forward. All of the efforts from planning toconstruction have been seamlessly carried out to create this target data and documentation neededwith minimal redundancy.The Final Result – The final result of this integrated approach is increased communication among theproject team members; efficient and accurate planning and engineering; significant time and costsavings for the reasons just mentioned, as well as integrated data collection; and the implementation ofa highly functional web‐based fiber asset management system.
