Upon receipt of necessary approvals and permits, a Micro-trench is cut into a roadway surface, the dimensions of which are determined by the size of the microduct and local regulations but typically vary between 1-1.75”wide x 9-18” deep. Once the cut is made, the microduct is placed within the micro-trench and held firmly in place to ensure that the duct remains at the bottom of the cut during restoration of the trench. Either a 5mm pea gravel or a non-shrink grout is used to fill in the trench up to 2” from the top of cut. Finally, either an infrared or “T” cut is used to seal the cut and restore the roadway to its initial conditions.
Once the civil work is complete, the fibre is then blown into the system using compressed air and blowing equipment. The fibre is blown end-to-end, tested and terminated at both ends to provide the optical pathway for service. Fibre networks can be designed as point-to-point, ring or star configurations and blowing fibre allows for connectivity from A to B without having to splice the fibres. Typical networks include connections from a Telco POP (point of presence) to the end user. The fibre is terminated within a FOSC (fibre optic splice closure) at the POP site and terminated within a Telco room of the end client location, which is generally a patch panel that connects to the client’s LAN.
