The Challenge and the Product Solution

The Challenge

Modernize Optical Access Networks Without Expanding Central-Office Space

Operators deploying GPON and higher-bandwidth PON access need to balance port density, operating environment and the transition toward advanced or virtualized network architectures.

The Product Solution

Lumia C16 is a compact 1U OLT with 16 Combo OLT interfaces supporting GPON and XGS-PON, and 10GE point-to-point operation in specified variants. The hardware supports conventional and disaggregated access architectures.

Technical suitability depends on the access topology, endpoint requirements and the supplied manufacturer specification. Review the optical and service design before deployment.

Translate documented technical features into deployment decisions for the teams selecting, installing and operating the optical network.

For Access-Network Architects

Deploy GPON and XGS-PON functions on a compact 16-port OLT, with variant-specific options for point-to-point access.

For Infrastructure Managers

Consider the 1U chassis and supported temperature envelope for sites with constrained rack depth or remote access locations.

For Network Operations

Choose between the documented integrated-OLT and disaggregated operating approaches to suit the operations model.

Engineering check:

The XGS-PON split-ratio line contains an apparent typographical anomaly (1:265); this figure is excluded pending confirmation. 10GE P2P availability is variant dependent.

Typical considerations and use cases described in the source. Final selection remains subject to project requirements.

  • Compact central offices and street cabinets
  • Smaller fiber access deployments
  • Migration planning from GPON to XGS-PON
  • Traditional or disaggregated PON access architectures

In a PON deployment, an OLT serves the optical access network through the optical distribution infrastructure. Choose subscriber blades, available uplink connectivity, optical split and any redundancy based on the actual configuration.

Illustrative PON network only. This diagram does not establish compatibility of specific OLT and ONT models, optical budget or performance.

Mix optical access technologies

Select between supported PON and P2P interface functions subject to hardware options.

Plan compact deployments

The 1U footprint and shallow rack depth suit space-constrained installations.

Support operational transformation

Conventional and disaggregated operation are described in the datasheet.

Manage traffic and access services

VLAN, hierarchical QoS, management and port-level security features are documented.
