PRELIMINARY SPECIFICATION


CommScope XE4202M R-OLT Module

The XE4202 10G EPON 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 10G EPON based services to their legacy DOCSIS® HFC network. The R-OLT lowers the cost of deploying PON, saves space and power using existing assets, 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 enclosure, 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 their 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 10G EPON ports, each supporting coexistent symmetric 10G/10G, and 1G/1G or Turbo EPON data speeds. Each 10G EPON port is fully interoperable with 1G and 10G ONUs via DPoE V2.0 OAM and supports 128 ONUs for a total of 256 subscriber ONUs per R-OLT module.


CommScope OLT Manager

The R-OLT is managed through its full lifecycle by the cloud-based CommScope OLT Manager software-defined networking (SDN) application. The OLT Manager integrates seamlessly with existing DOCSIS® provisioning and OSS systems through the CableLabs™ DPoE V2.0 specification with full flexibility for existing management, service provisioning and operational support systems and processes already in use in the HFC plant, such as DHCP, TFTP, NTP, syslog, ToD, SNMP and IPDR.

The high-availability OLT Manager facilitates and simplifies network management and programmability to support the high scalability requirements of operating a disaggregated PON network, by reducing the number of interface points to operator back-office systems. Each OLT Manager HA pair supports up to 200 R-OLTs (400 PON Ports) which equates to 51,200 ONUs with 1x128 splits per OLT Manager.

The R-OLT and OLT Manager system allows operators to cost-effectively migrate to standards-based 10G EPON as it becomes required by bandwidth demand and potential revenue, all while maintaining DOCSIS® provisioning compatibility.
