Why copper remains after a fiber upgrade
A fiber upgrade does not always retire every copper circuit. Military and government facilities may keep special analog circuits on copper because replacing the equipment or changing the service would add cost. Old cable can also remain in ducts after it stops carrying traffic.
Abacus supports the remaining work: assessing circuit conversion options, removing copper identified for retirement and installing fiber and innerduct in cleared pathways. Conversion technology can allow compatible legacy equipment to operate over fiber. The equipment, circuit requirements and transition schedule determine the approach for each site.
The work also changes the network records. Abacus reconciles those records and provides as-built documentation so maintenance teams can identify the infrastructure left in service. Cleared duct space can support later military construction, commonly called MILCON, as well as current fiber projects.
Plan the transition
Network planning and configuration recommendations establish the path from legacy copper to all-fiber connectivity.
Clear the legacy plant
Copper removal and circuit conversion free underground duct space for current and future fiber projects.
Install fiber and update records
Fiber and innerduct installation, testing and updated as-built records complete the transformation.
