TP-Link DeltaStream 1-Port GPON OLT

Description

What an OLT Is — and Who This Is For

This is operator/infrastructure equipment, not a CPE device. An OLT (Optical Line Terminal) sits at the network side of a GPON deployment — it’s the device that connects to your internet uplink and drives the fibre plant out to subscriber ONTs/ONUs at the premises. If you’re running the XC220-G3, XC220-G3v, XX230V or any other GPON CPE at the customer end, the DS-P7001-01 is the OLT that drives them.

The DS-P7001-01 is specifically sized for small-scale deployments: a single building, a business campus, an MDU, a small WISP, or an enterprise private fibre network — anywhere you need a proper managed OLT for up to 128 subscribers without deploying a full multi-port rack OLT.

GPON Port — 128 ONTs, Class C++

The single PON port (SFP slot, SC/UPC interface) runs at 2.5 Gbps downstream and 1.25 Gbps upstream at TX 1490 nm / RX 1310 nm on 9/125 µm single-mode fibre, with a 1:128 split ratio and a maximum logical transmission distance of 60 km. The Class C++ optical budget on the SFP module allows for deeper splits and longer reach than the standard Class B+ used in most GPON CPE.

⚠️ GPON SFP module sold separately. The PON port is an SFP slot — the OLT SFP module must be sourced separately. Confirm the SFP specification (Class B+, C+, or C++) matches your planned split ratio and reach before purchasing.

Uplink Ports

Uplink interfaces are 1× 10 Gbps SFP+ port and 1× 10/100/1000/2500 Mbps RJ45 port, plus a dedicated RJ45 MGMT port and RJ45 console port for out-of-band management. The dual uplink options — a 10G SFP+ for fibre backbone connectivity and a 2.5 GbE copper port as a secondary or alternative uplink — provide deployment flexibility in both data-centre and on-premises environments.

Power — DC or PoE

Power can be supplied via DC adapter (12V/2.5A) or 802.3at PoE (42.5–57V/0.6A), with a maximum power consumption of 17W. The PoE power option is particularly useful for deployments where the OLT is mounted remotely — on a comms board, in a cabinet without a power strip, or in a space served by an existing PoE switch — without needing a separate DC supply run.

Provisioning and Management

ONU authentication supports auto-authentication for zero-touch ONT onboarding. OMCI management is supported per ITU-T G.984.4/G.988 standards. Centralised management is available via the DeltaStream PON Management System (DPMS), SNMP, CLI, and web UI. DPMS supports batch configuration, firmware upgrades, reboots, multi-site management, intelligent network monitoring, and real-time network overviews across multiple OLT deployments.

L2/L2+ Features

Software features include Static Routing, IGMP Snooping and MLD Snooping, DHCP Server and Relay, ACL, 802.1X authentication, rogue ONU detection and isolation, uplink/downlink AES data encryption, IEEE 802.1p/DSCP QoS, Voice VLAN, multi-service traffic identification and rate limiting, and auto VoIP.
