PoP
Confirm the route, network role and required interface at this stage.
All network solutions
Aggregation, distribution & access
ISP and metro networks
Metro networks often combine existing ducts, short buried sections and frequent access points. Selection should balance compact diameter, fibre capacity, handling and the protection required along each route segment.
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
Pathway efficiency
Match cable diameter and installation method to duct occupancy and route congestion.
02
Access strategy
Plan branch points, closures, spare capacity and the fibre allocation used at each node.
03
Mixed-route protection
Identify sections needing armour or additional sheath protection before final design.
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.
