ISP ONT bypass (PON stick)


Internet service providers (ISP) usually provide their own custom optical network terminals/units (ONT/ONU) to their Fiber to home (FTTH) subscribers. These ONT units sometimes are only dridge devices and other times are routers (very basic routers) with builtin ONT. What happens when you require to have your own router with advanced features like port forwarding, DDNS, network automation, private cloud hosting, media center, etc... almost guaranteed that ISP custom routers will never provide (atleast with my ISP) plus the fiber will be connected directly to your router? Embrace the PON stick.

Where I live the tech used is Gigabit passive optical network (GPON), so I went for a GPON SFP stick since my router has an SFP port. These sticks running embedded linux to configure these modules.



When plugged in to the router, these sticks come preconfigured with an IP address (provided by the seller/manufacturer) that can be accessed through a web interface/telent/ssh.
Note: PON stick and PC should be on the same subnet (required only for configuration) and if thats the case and still no reply from module, make sure to plug in the fiber optic cable to the module.
Once all is settled then the module can be accessed through the web gui.


Here comes the tricky part, the configuration. It all depends on the configuration on the original ONT if its available because sometimes ISP's have specific configuration not available to the consumer it is embedded in the firmware. It is a trial and error testing phase, I suggest to take all the configuration on the original ONT and configure the PON stick with the available configuration. I suggest to visit this github link for good resource material.

Hope this was informative enough to perform all the required network operations having to power a single device rather than multiple devices plus having all the required features to perform on your network.
