The DS-P7501-08 is a 8-port combo OLT that serves XGS-PON and GPON subscribers from the same SFP+ ports. A provider can keep existing GPON ONUs running and bring XGS-PON customers on as they sign up, with no second headend.

Built for GPON to XGS-PON migrations

Each combo PON port supports GPON at 2.5 Gbps down and 1.25 Gbps up, and XGS-PON at 9.953 Gbps both ways, with split ratios of 1:128 and 1:256 respectively. Uplinks are 2x 100G QSFP28 and 2x 25G SFP28, and dual power supplies accept 2 AC, 2 DC or AC plus DC. TP-Link's overview lists Type B PON protection for uninterrupted connectivity.

Key features

  • 8 combo PON ports: XGS-PON and GPON on the same SFP+ cages
  • High-speed uplinks: 2x 100G QSFP28 and 2x 25G SFP28
  • Dual redundant power: 2 AC, 2 DC or AC plus DC
  • Type B PON protection per TP-Link's overview
  • Standard OMCI management: ONU auto authentication and rogue ONU isolation

System requirements

Combo PON SFP+ modules, such as the DS-PMA-Combo C+, for the PON ports, 9/125 µm single-mode fiber, and XGS-PON or GPON ONUs on the subscriber side. Uplinks need QSFP28 and SFP28 modules or cables.
