FAQ

Listed below are answers to our most commonly asked questions. Don't see your question?Contact our customer service team. We would be glad to assist you.

What is an optical network terminal (ONT)? How does it differ from a regular modem?

An optical network unit (ONU) is an end device in a fiber optic network that converts optical signals transmitted via fiber optics into electrical signals (for use by routers, computers, and other devices), and vice versa.

What is the architecture of a fiber optic network (PON)?

Fiber optic networks typically use a passive optical network (PON) architecture, which is divided into three layers

What are the functions of the PON port and LAN port on an optical network terminal (ONT)?

PON port (fiber optic interface): Connects to the fiber optic cable entering the home and receives optical signals (usually SC/APC interface, blue square head).

Why does the optical network terminal need to register LOID/SN?

LOID (Logical Identifier) or SN (Serial Number) is the credential used by operators to bind user identities, and is used for OLT authentication of optical modems.

Optical modem dialing vs. router dialing: which is better?

Ordinary users: Optical modem dialing. Game/NAS users: Switch to bridge mode and dial up using a high-performance router.

How to determine whether the fiber optic signal is normal?

Check the optical modem indicator lights Log in to the optical modem management interface: Check the optical power (unit: dBm)
