The bridge mode feature allows the device to function exclusively as a modem, passing the public IP address directly to an external router . However, this feature is frequently restricted or hidden by ISPs like Claro through firmware locks or JavaScript scripts that disable the "Apply" button. Key Features of Bridge Mode

In contrast, bridge mode limits the router to Layer 2 of the network (the data link layer). This effectively turns the ZTE F689 into a pure modem, disabling its routing, NAT, and firewall functions. All traffic is passed directly to a downstream router (like an ASUS, TP-Link, or Ubiquiti device), which then handles all routing and security duties.
The ZTE F689 is a standard Optical Network Unit (ONU) frequently deployed by ISPs across Asia and parts of Europe. When used in Bridge Mode (where the device acts strictly as a fiber-to-ethernet converter, passing the public IP to a third-party router), it generally performs well. It is stable and transparent, but it lacks the processing power of modern optical modems, which can create bottlenecks for users with ultra-high-speed internet plans (1Gbps+).
