XGPL-16000 16-Port XGS-PON OLT with 8-Port 10G SFP+ + 2-Port 100G QSFP28

Description

The 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.

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.

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.

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.
