PLANET XGPL-16000 optical line terminal (OLT)

High-Performance 16-Port XGS-PON OLT with 40G/100G Uplink Capability

PLANET XGPL-16000 is a high-density 16-Port XGS-PON Optical Line Terminal (OLT) designed for next-generation fiber broadband access networks. It integrates 16 XGS-PON ports, 8 10G SFP+ ports, and 2 40G/100G QSFP28 uplink ports, offering exceptional scalability and bandwidth aggregation for large-scale deployments.

Key Features:

-16 XGS-PON SFP slots with a 1:256 split ratio per port
- Two 40G/100G QSFP28 uplink interfaces for high-capacity backbone connectivity
- Eight 10G SFP+ ports for flexible service expansion or link redundancy
- Dual hot-swappable power supply (AC/DC/mixed) with front-to-back airflow
- Full L2/L3 features including VLAN, Q-in-Q, IGMP snooping, LACP, and RIP/OSPF
- Powerful QoS and SLA mechanisms with DBA per ONU
- CLI, SNMP, Telnet, and out-of-band management support


High-capacity Aggregation and Access

The XGPL-16000 supports a 1:256 split ratio per port, enabling access to up to 4096 ONUs in total. Each XGS-PON port provides symmetric 10Gbps downlink/uplink bandwidth, significantly outperforming legacy GPON systems. It supports N1/N2 XGS-PON transceivers and multiple GPON optical classes (B+/C+/C++/C+++/D+), making it backward compatible and deployment-flexible.


Strong Standards Compatibility

The XGPL-16000 is compliant with ITU-T G.9807/G.987/G.988 standards and adheres to China Telecom’s GPON Technical Specification CTC 2.0. It also supports Ethernet-II, IEEE 802.1Q VLAN, Q-in-Q, and LACP, ensuring interoperability with a wide range of equipment and ONUs. The system supports Layer 2 multicast protocols, including IGMP snooping and MLD snooping, ensuring smooth IPTV and video-on-demand service delivery.


Powerful QoS and SLA Management

The device supports comprehensive QoS mechanisms, including IEEE 802.1p, CoS, WRR, SP, and FIFO queue scheduling, ensuring differentiated service levels for various traffic types. It also features DBA (Dynamic Bandwidth Allocation) and SLA (Service Level Agreement) functions per ONU, providing precise bandwidth control and carrier-grade traffic assurance.


Carrier-class Security and Reliability

The XGPL-16000 offers advanced security features, such as ACL (Access Control List), port isolation, broadcast storm suppression, and data encryption over PON interfaces. The system supports Type B and Type C optical path protection, abnormal ONU emission detection, and trunk fiber link protection, ensuring fault tolerance and minimal downtime in critical networks.


Modular, Redundant, and Eco-Friendly Design

The XGPL-16000 adopts a modular dual-power-slot design, supporting hot-swappable AC, DC, or mixed AC/DC power modules. The fan system uses a front-to-back airflow layout, optimized for rack-mounted deployments. It supports EMC level 3, operates under harsh temperature and humidity conditions, and provides low-noise and low-power operation to meet long-term deployment needs in data centers and equipment rooms.


Flexible and Efficient Management

The device offers multiple management interfaces, including CLI (console), Telnet, SNMP, and out-of-band Ethernet management. It supports TFTP remote software upgrade, debugging output, system logs, and batch ONU provisioning. With strong system maintainability and remote operation capabilities, it ensures simplified network operation and management (OAM).
