After an in-house design of the fiber build to the distribution access point, field engineers go to each pole to determine if any modifications are required in order to support the fiber, keeping in mind NESC clearance requirements. Line crews will change poles, move transformers from one side of the pole to the other, move wires on the pole, add new anchors to the poles, and perform other work to allow the fiber to be placed later.
In addition to engineering the design, other steps include obtaining permits, staking, coordinating with Miss Utility, finalizing ROW easements, and procuring material, all of which are done before construction can begin. This work has the widest variance in time of all construction phases. The make-ready construction phase can take five months or more to complete.
The construction team will bury fiber cables underground or string them from poles to connect your neighborhood to our fiber network. This process can take up to another three months. You may see us digging holes during this stage. When we’re done, we will return all sidewalks and green spaces to the way we found them. Fiber construction can take four to eight weeks on a circuit.
Once the strand and fiber are placed, splicers will make splices at each end and tap point. They splice the necessary cables at each point and mount the splices in enclosures secured to the distribution poles or in pedestals. The splicing work can take another three to six weeks for the main lines.
The next step is service drop construction. This work can be done in parallel with some of the earlier work, or it might be done after the main line fiber is in place. The drop crews extend the fiber from the nearest splice point to the structure receiving service and leave coils of fiber in each location.
The final outdoor step in fiber construction is the splicing of the drop. The splicer connects the last length of fiber at the tap point and also mounts a network interface device (NID) at the structure with the final splice inside the NID. The service is now ready for in-home installation.
The final step is to install the ONT/router in the consumer’s home and connect it to the outside NID. The installer will call the consumer to schedule this appointment once the above steps are complete.
As you can see, there will be multiple different contractors and vehicles passing each point over several months before the service is ready for final installation.
