Fiber Optic Telecom Co., Ltd

GPON, EPON & XGS-PON ONT/ONU — China Supplier & Manufacturer

An Optical Network Terminal (ONT) — also called an Optical Network Unit (ONU) — is the subscriber-side device in a passive optical network that converts the optical signal from the OLT into Ethernet, voice and video services. Fiber Optic Telecom (FOT) supplies GPON, EPON, XG-PON and XGS-PON ONT/ONU devices in bridge, home-gateway, WiFi 6, PoE, CATV triple-play and SFP stick form factors for residential FTTH, enterprise and FTTR deployments.

Specifications reflect the published catalog. Confirm the exact model, optional features and compatibility with FOT before ordering.

How to Choose

  • Match the ONT to your OLT PON standard — GPON/EPON dual-mode ONTs auto-detect the OLT; XGS-PON ONTs require an XG/XGS-PON OLT. Confirm the standard before ordering.
  • Size the WiFi for the subscriber count — WiFi 6 (AX3000) ONTs suit dense multi-device homes; bridge ONTs pair with a separate WiFi 6 router for best coverage.
  • Decide bridge vs. routing — bridge (SFU) ONTs are simplest behind an existing router; HGU/routing ONTs handle PPPoE, NAT and VLAN for standalone deployments.
  • Add voice and CATV only when needed — FXS POTS ports add VoIP; an RF CATV module adds 1550 nm cable TV for triple-play over a single fiber.
  • Check the power and installation environment — PoE/PoF ONTs power cameras and APs without local power; 86-panel and SFP stick ONTs fit FTTR and space-constrained installs.

Frequently Asked Questions

Equipment Buyer Questions

What is the difference between an ONT and an ONU?

The terms are often used interchangeably. Strictly, an ONT is the optical terminal at the customer premises in a PON, while an ONU may sit further from the subscriber in FTTB/FTTC. FOT supplies both as subscriber-side PON devices.

Can a GPON ONT work on an XGS-PON OLT?

No — a GPON ONT operates at 1490/1310 nm and cannot register on an XGS-PON OLT (1577/1270 nm). Use an XG/XGS-PON ONT, or a dual-mode XPON ONT only if the OLT is GPON/EPON.

Do FOT ONTs support third-party OLTs?

XPON dual-mode ONTs are compatible with mainstream OLTs (Huawei, ZTE, FiberHome, etc.) via OMCI/OAM. Share your OLT model and firmware so FOT can confirm interoperability.

Which ONT supports VoIP and CATV triple-play?

ONTs with an FXS port provide VoIP (SIP), and ONTs with an RF CATV module deliver 1550 nm cable TV. The 2GE+1POTS+CATV+WIFI5 ONT combines data, voice and TV over one fiber.

What is an SFP stick ONT?

An xPON Stick SFP ONT is a PON terminal in an SFP form factor with a built-in MAC, drawing power from the host port — useful for FTTH and enterprise deployments where a pluggable PON interface is required.
