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)
This optical SFP GPON module enables you to transfer your GPON subscriber information between different UNO devices without having to request a “formal” activation request from the ISP. You also got telnet access with root privileges for working in command-line interface (CLI) mode.
Keep in mind that in some countries, changing a subscriber ONT/UNO unit information provided by the ISP is not legal and can result in service disconnection due to security risk issues, therefore such activities are solely on the user’s own responsibility.
Price and Availability
The Optfocus official AliExpress factory store is currently selling a module that is fully compatible with GPON/EPON/XPON infrastructures. Below, you will find a product comparison table that will efficiently clarify the key differences among all the models.
| Specifications | Package | Data Rate | Wavelength | Laser | Interface | model | Receiving Sensitivity |
| XPON ONU | SFP | GPON:1.25Gbps/2.5Gbps EPON:1.25Gbps/1.25Gbps | Tx1310/RX1490 | DFB | SC | Adaptive EPON/GPON | <=-28dBm |
| 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 |
Before placing your order, it is crucial to thoroughly review your ISP’s requirements and accurately identify the type of interface you need. Additionally, make sure to confirm whether the optical input port should be SC UPC or SC APC. Taking these steps will ensure a seamless and successful transaction.
