These networks are fundamentally different


Denser Networks Deeply Fiberized

Fiber intensive network to support latency and capacity

requirements

Access layer end points will multiply

Future ready network


Leading to multiple implementation challenges

Faster to market Reduced ownership cost

Performance degrades with time due to existing network’s non-compatibility

with newer transmission technologies eg. NG-PON, XGS-PON etc.

Deteriorated optical performance

1

Requirement of skilled manpower and the mandate for structured laying

process pushes time for a new fibre network provisioning project

Slow provisioning

2

Although Fibre & Cable form <10% of a Telco CAPEX, there are process and

time costs which push the CAPEX upwards for a green field project

Cost intensive rollout

As networks become dense, they are more susceptible to bend losses


Increasing losses with increasing geographical spreadMore no. of tight bends & turns

Limited tech migration with legacy solutionsAt higher wavelengths and tighter bends
