PRELIMINARY SPECIFICATION


CommScope FLX XP4202M R-OLT Module

The XP4202 XGS-PON R-OLT (Remote Optical Line Terminal) module for CommScope HFC Nodes and VHubs is specifically designed for cable MSOs to substantially increase the ROI of their existing network infrastructure by adding high bandwidth XGS-PON based services to their legacy DOCSIS® HFC network. The R-OLT lowers the cost of deploying PON, saves space and power using existing fiber and enclosures, and drives PON based services through the last mile, enabling the migration to FTTX through seamless coexistence of RF/HFC, RFoG overlay, and digital returns all in the same node or VHub, supporting nodes with coexistent RF/PON, or VHubs with RFPON (RFoG+PON overlay) or PON-only services.

The R-OLT incorporates full traffic management and PON MAC/PHY capabilities in a compact module and utilizes standard long haul 10GE uplinks, including CWDM and DWDM options, to connect to the S-Leaf switch/router in the Converged Interconnect Network (CIN), so operators can extend the deployment of FTTX to serve customers at distances well beyond the typical 20km reach of centralized chassis-based PON, while utilizing their transport backhaul fiber resources efficiently. For subscriber access, the R-OLT includes two XGS-PON ports, each supporting coexistent symmetric 10G/10G XGS-PON, 2.4/1.2 GPON or combo mode (coexistent GPON and XGS-PON). Each XGS-PON port is fully interoperable with GPON and XGS-PON ONUs via OMCI and supports 128 ONUs for a total of 256 subscriber ONUs per R-OLT module.


CommScope FLX Virtual OLT (vOLT)

The CommScope vOLT is a virtual OLT application supporting a software-defined networking architecture (SDN) that separates theManagement plane from the control and data planes found in the physical network function (PNF) of the R-OLT. By centralizing thecontrol plane, the vOLT facilitates network management and programmability to improve scalability of operating a highly scaled, disaggregated network with PON DAA devices like the R-OLT, thus simplifying and reducing the number of interface points to operator back-office system. Key features of the vOLT include:

• Seamless integration of the management and assurance of multiple R-OLTs resulting in a fully managed service deployment using existing operational production processes and procedures
• Full lifecycle management of multiple R-OLTs from initial deployment through the application of services and subscriber provisioning, and integration into monitoring and network operational support systems.
• For GPON and XGS-PON based PON services, integration into the northbound provisioning and management systems
• Full standards-based interfaces to northbound SDN and telemetry gathering applications
