SI3000 Lumia G16 – GPON OLT

Iskratel Lumia C16, SI3000 Lumia XG8 and SI3000 Lumia G16 are compact 1U OLTs for Combo PON, XGS-PON and GPON, respectively, optimised for smaller fibre-access deployments and for heterogeneous residential and business access.

These compact 1U OLTs withstand harsh temperature conditions (up to +65 °C ambient), and excel in ultra-compactness: ETSI-compliant 235 mm depth saves rack space at CO locations and fits easily into street cabinets, providing the latter with internal control as well.


  • Based on the latest state-of-the-art GPON and XGS-PON chipsets.
  • Exquisite bandwidth utilisation and high split ratio.
  • Network processor-based, SDN-enabled broadband platform.
  • Service- and app-awareness provides control, effective QoS management and policy enforcement.
  • Support for multi-provider deployment scenarios, including virtual unbundling and open access.
  • Easy management using service profiles, fast integration into operators’ OSS/BSS.
