Huawei OptiXstar K662d
HUAWEI
The Huawei OptiXstar K662d is a desktop slave device in Huawei's FTTR (fiber to the room) all-optical home solution. It needs to be used in conjunction with the main FTTR, supports fiber/Ethernet uplink, and provides Gigabit dual-band Wi-Fi 6 and Gigabit network ports.

| Core Chipset | Huawei's proprietary HiSilicon chip |
| Buttons and Indicators | Power indicator, fiber registration status indicator, Wi-Fi indicator, network port status indicator, WPS/Reset button |
| Power Supply | External DC power adapter (typically 12V/1A) |
| Dimensions | Approximately 100mm x 100mm x 30mm (very compact) |
Main Functions and Application Scenarios
1. As an FTTR Sub-Router (Core Application)
This is the most typical use case for the K662D.
Networking: Run a single fiber from the FTTR master optical modem (such as the HN8145XR) to the living room, bedroom, or study.
Connection: Plug this fiber into the K662D's GPON port.
Effect:
Whole-Home Wi-Fi: The K662D and the master optical modem form a unified Wi-Fi network with the same SSID (Wi-Fi name) and password.
Seamless Roaming: As you move around the house, your phone, tablet, and other devices automatically switch to the K662D or master optical modem with the strongest signal, ensuring uninterrupted calls and video conferences.
Gigabit to Room: Fiber transmission is virtually lossless, ensuring near-gigabit speeds in every room.
2. As a Standalone Optical Modem
In some areas or with specific broadband plans, carriers may directly provide the K662D as the master optical modem.
Connection: Plug your fiber optic cable directly into the K662D's GPON port.
Function: It now integrates an optical modem, router, and Wi-Fi functionality into one, meeting the daily internet needs of most households.
3. Use as a Standalone Wi-Fi 6 Router
If you already have a primary optical modem but its Wi-Fi performance is poor, you can use the K662D as a high-performance Wi-Fi 6 router.
Connection: Use an Ethernet cable to connect the primary optical modem's LAN port to the K662D's WAN/LAN port.
Setup: In the K662D's management interface, set its operating mode to "Router Mode" or "AP Mode."
Router Mode: The K662D creates an independent subnet and performs NAT forwarding, providing more comprehensive functionality.
AP Mode: The K662D only extends the wireless signal, while the primary optical modem/router handles all network management. This makes it more suitable for seamless roaming (requires integration with other APs).
