There are applications in the market today that are more practically solved with customer owned or leased conduit. There is no better way to future proof your network than conduit ownership that allows you to grow beyond your expectations.
There are Government and Private Enterprise scenarios that mandate a "non-shared" network design. DF&I provides not just private conduit, but separate manholes, hand holes, and access points when physically possible.
Conduit customers have access to manholes and hand holes that fiber customers do not. You are in control of your own splicing, record keeping, and cable management. DF&I will monitor the system and maintain the conduit, but you have complete control of your cable.
