The included SFP runs at 1310nm. Avoid APC (GREEN) connectors, as they are not compatible. If needed, you can swap the SFP for multimode or other options. **Q: I plan to use it as a standalone unit – what should I watch for?** A: This converter cannot replace ISP ONTs (e.g., FiOS, GPON). It works only with standard Ethernet-to-fiber links. Ensure the wavelength matches on both ends (e.g., 1310nm TX - 1310nm RX) and use a compatible LC UPC patch cord **Q: What is the most common fault if the converter does not come up?** A: The most common issue is TX/RX mismatch—swap the RX and TX fibers at one side. If using it standalone, ensure the wavelengths match on both ends (e.g., 1310nm TX - 1310nm RX). Also check if fiber module speeds match - i.e. 100FX or 1000FX **Q: Can I use this as a replacement for Verizon FiOS, Google Fiber, or other ISP fiber services CPE?** A: No, this cannot replace ISP ONTs like Verizon FiOS, Google Fiber, AT&T Fiber, or CenturyLink. These providers use GPON/XGS-PON, which requires their own ONT. This converter works only for standard Ethernet-to-fiber extensions, not ISP connections. **Q: Can I use different SFP modules, can I replace module?** A: Yes! The SFP slot supports all types of fiber modules, including single-mode, multimode, BiDi, CWDM, and more. It works with both 155M and 1.25G SFPs, giving you full flexibility to match your network needs. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works flawlessly *by R***N on December 16, 2024* These are great for data transmission over long distances.
