Fiber intensive network to support latency and capacity
requirements

Future ready network
7© 2019-2020 Sterlite Technologies Limited
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
