Ubiquiti UISP Fiber XGS-PON ONU/ONT

Description

XGS-PON — Symmetric 10 Gbps

The key distinction from everything else in this fibre lineup is symmetry. The UISP-FIBER-XGS uses an ITU-G.9807 XGS-PON WAN port with a total non-blocking line rate of 9.95 Gbps downstream and 9.95 Gbps upstream — fully symmetric multi-gigabit throughput. Where GPON delivers 2.488/1.244 Gbps and the Fiber XG delivers an asymmetric 9.95/2.44 Gbps, the XGS is the unit for deployments where upstream bandwidth matters as much as down: high-density residential builds, enterprise premises running cloud workloads, or ISPs delivering symmetric 10G service tiers.

The SC/APC WAN port operates at TX 1270 nm / RX 1577 nm with a normal TX range of 4 to 9 dBm and RX range of −9 to −26 dBm, using scrambled NRZ line coding, at a maximum physical reach of 20 km.

10 GbE LAN — Matched to the PON Capacity

The LAN port is a multi-rate 100/1000/2500/5000/10,000 MbE auto-negotiating RJ45, capable of terminating the full 10 Gbps PON capacity to downstream equipment. This is a meaningful differentiator over the Fiber XG, whose 2.5 GbE LAN port caps the effective client throughput well below the PON’s upstream capacity. To utilise the full 10 GbE LAN rate, downstream equipment (router, switch, or NIC) must also support 10 GbE.

OLT Compatibility — XGS-PON Port Required

The UISP-FIBER-XGS is only compatible with the UISP Fiber OLT XGS and cannot be used with third-party OLTs. The UISP-FIBER-OLT-XGS supports XGS-PON, XG-PON, and GPON ports concurrently across its eight PON ports, so an XGS-PON port on the OLT is required for this unit specifically.

⚠️ XGS-PON only — not GPON or XG-PON. This unit will not register on GPON-only OLTs (UF-OLT, UF-OLT-4) or on an XG-PON port. It requires an XGS-PON port on the UISP-FIBER-OLT-XGS.

Power — USB-C Only

Unlike the Fiber XG and WaveFiber ONU which support both USB-C and 24V passive PoE, the UISP-FIBER-XGS is powered exclusively via USB-C 5V DC / 3A (included adapter), with a maximum power consumption of 8W. There is no passive PoE input on this unit — installation planning should account for a USB-C power point at the premises.

Optical Signal LEDs and Management

The three-LED PON signal strength indicator uses the same pattern as other UISP fibre CPE: all off during bootup; 1× orange for too low (below −27 dBm); 1× white for low (≥ −27 dBm); 2× white for good (≥ −24 dBm); 3× white for strong (≥ −12 dBm); 1× orange + 2× white for too strong (≥ −9 dBm); 3× orange for no signal. Management runs through the UISP platform (version 1.5.7 and later).
