TP-Link DeltaStream 8-Port GPON OLT

Description

Eight Ports, 1024 ONTs

The DS-P7001-08 provides 8 PON ports (SFP slots), each supporting a 1:128 split ratio, accommodating up to 1024 ONTs across the device. Each port is independent, so the eight legs can serve separate buildings, floors, or distribution zones simultaneously — or be combined via passive splitters to maximise reach and density within a single zone. GPON data rates are 2.5 Gbps downstream and 1.25 Gbps upstream per port at TX 1490 nm / RX 1310 nm on 9/125 µm single-mode fibre, with SC/UPC connectors and Class C+ optical power, at up to 20 km transmission distance.

⚠️ GPON SFP modules sold separately. All eight PON ports are SFP slots. Class C+ OLT SFP modules must be sourced separately. Confirm optical budget, split ratio, and reach requirements before purchasing.

Dual 10G SFP+ Uplinks — Double the -04

Uplink interfaces are 2× 10 Gbps SFP+ ports, 1× 10/100/1000 Mbps RJ45 uplink, 1× RJ45 MGMT port, 1× RJ45 Console port, and 1× Alarm port. The step from one 10G SFP+ (on the -04) to two is meaningful at this ONT density: with up to 1024 subscribers, the dual 10G SFP+ ports allow link aggregation or active/standby uplink redundancy to the aggregation layer, protecting against a single uplink failure.

Hot-Swappable Redundant Power Supplies

The DS-P7001-08 includes dual redundant hot-swapping AC+DC power supplies, supporting AC input (100–240V, 50/60Hz) and DC input, with a maximum power consumption of approximately 70W. Unlike the built-in (non-swappable) PSUs on the -04, the -08’s power modules can be replaced under load — no downtime to swap a failing PSU in a live deployment. This is the carrier-class reliability feature that justifies the -08 in ISP and operator environments where planned maintenance windows are impractical.

Provisioning and Management

ONU management uses standard OMCI per ITU-T G.984.4/G.988, with ONU auto-authentication for zero-touch onboarding, and supports AES 128-bit encryption for uplink and downlink data transmission. Centralised management is available via the DeltaStream PON Management System (DPMS), SNMP, CLI, and web UI — the same management stack as the -01 and -04, with DPMS supporting batch configuration, firmware upgrades, reboots, multi-site management, and real-time network monitoring across the full fleet.

L2/L2+ Feature Set

Software features include complete L2 functions, Static Routing, IGMP Snooping/MLD Snooping, DHCP Server and Relay, ACL, 802.1X authentication, ARP Inspection, IP Source Guard, rogue ONU detection and isolation, AES 128-bit uplink and downlink data encryption, multi-service traffic identification and rate limiting, QoS, and Voice VLAN.
