Infraplus Consulting was engaged to create a High Level Design (HLD) for a fiber optic network spanning 1407 km and connecting 87,614 homes in Florida, USA. This Greenfield project involved detailed planning, starting from OLT (Optical Line Terminal) location selection, followed by DA (Drop Area) boundary and fiber drop planning.

Infraplus worked with Shapefile and Excel data provided by the client, which included home passes and other important mapping data. The project started with the identification of the OLT as the central location, from where fiber would be distributed through feeder routes to DA boundaries.

The fiber network design involved placing Duct Access Points (DAP) at every drop boundary, ensuring smooth connectivity from home passes through 1-way and 2-way conduit systems. Additionally, splitters were placed at every cabinet based on the 1:32 ratio for DA boundaries. Fiber allocation was carried out with precision, ensuring that MDU boundaries were well-defined and correctly linked to fiber distribution.

Infraplus ensured that all network components, such as enclosures, access points, equipment, cables, paths, and boundaries, followed the required guidelines for proper network performance and future scalability.

Scope of Work:

1. Network Design & Planning:

OLT location selection and DA boundary planning
Design fiber routes and plan feeder and distribution networks
Place Duct Access Points (DAP) at drop boundary entrances
Connect home passes with DAP through 1-way and 2-way conduit systems

2. Fiber Allocation & Connectivity:

Splitter placement at each cabinet based on the 1:32 ratio for DA boundaries
MDU boundary design and fiber allocation
Feeder connectivity from OLT to DA and fiber blowing to DAPs
Drop cable design from DAP to premises

3. Data Management & Attribute Assignment:

Ensure correct fiber network attributes (Enclosure, Access Point, Equipment, Cable, Path, Boundary, DA)
Attribute management in Shapefile layers
Integration of data into planning files for easy reference and future work

4. GIS Mapping & Design Delivery:

GIS-based design for all network components
Complete planning shapefiles for network implementation
Bill of Material (BoM) in Excel format for cost and material estimation

Deliverables:

Planning shapefiles for the fiber network design, including DA boundaries, fiber routes, and access points

Bill of Material (BoM) in Excel format, detailing the materials required for fiber network construction

GIS data for network components, conduit placement, and fiber drop connectivity
