When using custom GPON SFP ONTs (Small Form-factor Pluggable Optical Network Terminals), it’s important to be aware of potential risks and how they can affect not only your connection but also others on the same network.
Always monitor for issues, and consider switching to certified models if problems persist to avoid affecting other users.
[!WARNING] A technician once encountered an SFP ONT that was causing collisions, which affected the entire network. They had to replace the device with a different model (XGS PON) to restore stability and avoid further issues. While experimenting with custom devices can be fun, it’s essential to understand that you share the network with other customers.
tl;dr quote by @03HemiNorthIL at Reddit
If you’re experimenting with custom GPON sticks, keep the following in mind
[!NOTE] Using GPON Sticks can potentially improve throughput for plans offering 2 Gbps by bypassing the limitations of a typical Gigabit Ethernet ONT. However, this will not provide any speed boost or "hacking" beyond your subscribed plan.
[!CAUTION] If your ISP detects the use of unauthorized commands or illegal activity, they have the right to ban your service and impose hefty fines for disrupting the PON network.

Code | Full name | Meaning |
---|---|---|
PPTP | Physical Path Termination Point | Directly binds to a specific LAN port, with OLT managing VLANs and settings on the ONT. |
VEIP | Virtual Ethernet Interface Point | Acts like a virtual interface (e.g., tap0 ), allowing ONT firmware to assign to LAN ports, router mode, management, or VoIP. |
[!NOTE] Since a PON SFP Stick has only one interface to the host, its firmware may struggle to manage VLANs from both PPTP and VEIP. Many firmware versions simply bridge all VLANs from both, regardless of configuration, which can lead to issues:
- If the same VLAN ID is used for different services on PPTP and VEIP, the stick’s firmware might bridge them together without distinction, potentially causing issues with DHCP/IPoE.
- Most firmware prioritizes PPTP first, using VEIP only if PPTP is unavailable. A few firmware versions allow manual VLAN selection for bridging, independent of PPTP/VEIP.
Also, note that if your ISP uses ME 148 (which enforces PPPoE and routing on the ONT), you may not be able to bridge directly to your own router. For bridge mode, it's best to contact your ISP for assistance.
Many ISPs use PPTP to bind specific LAN ports to different service providers, allowing one ONT to support multiple ISPs. For instance, LAN 1 might be configured for ISP 1, LAN 2 for ISP 2, and so forth. This setup is common in areas served by single fiber vendors that host multiple ISPs.
However, this multi-ISP setup can pose issues for PON Sticks, as they might struggle to bridge VLANs on any port other than LAN 1. This limitation occurs because PPTP configurations, along with the Forwarding Operation (FwdOp), are often designed specifically for ONTs and may not be fully recognized by PON sticks. Some advanced setups attempt to resolve this by using an HGU MIB file to "trick" the OLT (Optical Line Terminal) into accepting the ME 84 and ME 171 operations, allowing better compatibility.
Some OLTs from manufacturers like Calix and Nokia, which support Universal ONU, may provide a “false O5” state, which can be misleading. A device might reach the O5 state (the operational stage where data transmission typically begins) even with incorrect Serial Number or PLOAM Password. In this scenario, the OLT might allow the connection to reach O5 but won’t actually push any VLAN configurations (typically ME 84 & ME 171).
To resolve this, double-check all configuration parameters, including the serial number and password. If the connection still doesn’t work after verification, the OLT may be requiring Vendor-Specific Managed Entities (ME) (IDs 350-399) which are sometimes mandated by ISPs for authentication or additional configuration.
A device entering an O2-O5 loop (oscillating between states) could indicate a similar issue as the "Fake O5" scenario. Another common reason for this loop is low optical receive power (RX), where the power level drops below the acceptable threshold (e.g., <= -23 dBm
). When this happens, the OLT may refuse to allow a stable O5 state to maintain PON performance.
To address an O2-O5 loop caused by low RX power:
[!CAUTION] If you have attempted all troubleshooting steps and are still unable to establish a connection, it’s recommended to stop further adjustments. Persistent errors or invalid configurations will be flagged by your ISP, and further experimentation can unintentionally disrupt the entire PON network in your area, affecting other users.
Please remember to use these tools responsibly and respect the shared network environment.
