Core site
Confirm the route, network role and required interface at this stage.
All network solutions
National, regional & metro transport
Telecom backbone networks
Backbone design begins with route protection, fibre capacity and restoration strategy. OFS can configure duct or armoured constructions around the installation method, mechanical duty and approved network standard.
Network path
Design each section as part of the whole.
The cable role changes along the network. Use the complete path to define capacity, protection and installation duty.

Design priorities
Decisions that shape the cable.
01
Capacity planning
Allow for the commissioned fibre count, dark-fibre allocation and practical network growth.
02
Route protection
Match armour, sheath system and water blocking to duct, trench and ground conditions.
03
Section engineering
Confirm pulling length, drum plan, joint locations, bend limits and installation tension.
Suitable starting families
Compare cable platforms for this network.
These families are practical starting points, not automatic final selections. The approved project TDS determines the supplied construction.
