How to configure the settings
Step No. 1: Check your GPON ONT device information. The location of the information is typically on a label or sticker on the rear side of your device.
Step No. 2: Obtain the GPON SN, PLOAM Password.
Configure your network connection to use a static IP address, then navigate to the web interface at 192.168.1.1 to ensure that all settings are saved.
Step No. 3: Use telnet to connect to the module’s IP address 192.168.1.1 and add the specified parameters (Please review the example provided below).

What’s so special about the product?
Let’s dive right into the key features of the product. The OFS-GS-001 Module comes with an internal MAC address and tons of flexible options you can configure and tweak such as entering PON/LOID/PLOAM information, MAC filtering, Firewall, VLAN, DMZ and many more options worth exploring.
Optfocus has added a useful WAN option for setting the connection mode. There you can select bridge mode or PPPoE option which is commonly used in GPON optical fiber networks.
Replacing the ISP ONT/ONU with a PON stick (SFP module)
With this optical SFP GPON module, you can seamlessly transfer your GPON subscriber information between different UNO devices without needing a formal activation request from the ISP. You also got telnet access with root privileges for working in command-line interface (CLI) mode.
It’s important to note that in certain countries, altering the information of a subscriber ONT/UNO unit provided by the ISP may be considered illegal and could lead to service disconnection due to security concerns. Consequently, users are solely responsible for any such activities.

| GPON ONU | SFP | 1.25Gbps/2.5Gbps | Tx1310/RX1490 | DFB | SC | GPON | <=-28dBm |
| EPON ONU | SFP | 1.25Gbps/1.25Gbps | Tx1310/RX1490 | DFB | SC | EPON | <=-28dBm |
To ensure a smooth ordering process, it is vital that you carefully examine your ISP’s requirements and correctly determine the specific interface that suits your needs. Additionally, if you are using an SC APC (Green) module with your ISP, you will need to buy an adapter converter from SC APC to SC UPC.
