TP-Link DS-P7501-08 8-Port XGSPON/GPON Combo OLT
Overview
The DS-P7501-08 is an 8-port XGSPON and GPON combination optical line terminal (OLT) built for ISP infrastructure deployments. This device terminates fiber subscriber lines on a single chassis, eliminating the need to run separate GPON and XGSPON equipment in parallel—a real cost and footprint saver when you need to support both legacy GPON and next-generation 10G XGSPON subscribers on the same network segment.
The combo architecture means one device handles mixed subscriber tiers: GPON (2.5 Gbps) and XGSPON (10 Gbps) on the same 8-port SFP module bank. Uplinks are delivered via dual 100G QSFP28 ports and dual 25G SFP28 ports, giving you multi-gigabit backhaul to your core switch or router without bottlenecking subscriber throughput. Hot-swap redundant power (AC, DC, or mixed) ensures OLT availability during maintenance or power events.
Compatibility
The DS-P7501-08 pairs with standard GPON and XGSPON subscriber units (ONTs) and routers from major vendors that conform to ITU-T G.984 (GPON) and ITU-T G.9701 (XG-PON/XGSPON) standards. Backhaul integrates with carrier-class Ethernet switches and routers supporting 100G QSFP28 and 25G SFP28 optics. Console management via RJ45 (1Gbps dedicated management port); network management via TAUC (TP-Link's unified ISP management platform) or standard SNMP over the 1Gbps management interface.
Installation Notes
Mount in a 19-inch rack with standard hardware (not included). Requires dual AC (110–240V) or dual DC (–48V nominal) power feeds for redundancy; mixed AC+DC is also supported. SFP+ transceivers for GPON/XGSPON subscriber ports and QSFP28/SFP28 transceivers for uplinks must be sourced separately according to your fiber distance and vendor certification requirements. Broadcom chipset handles ONT authentication and traffic scheduling at line rate; no CPU offload needed for subscriber provisioning.
