Typical Applications
This slim DIN rail Gigabit switch with open SFP slot can be used in two common deployment scenarios. In both cases, the SFP slot allows flexible fiber uplink selection based on the required distance, fiber type, and connector format.
1. Fiber-to-Copper Distribution for Multiple Ethernet Devices
In the first example, the switch receives a Gigabit fiber uplink from a central switch through the open SFP slot. It then distributes the Ethernet connection to multiple copper devices through its four 10/100/1000Base-T RJ45 ports. This is a practical solution when one fiber link needs to be expanded into several copper connections at the remote side.
Typical uses include connecting multiple IP-based devices such as industrial controllers, PCs, HMI panels, cameras, gateways, or other standard Ethernet equipment inside control cabinets, factory networks, or field installations.
2. Expanding a Third-Party Fiber Device with Additional RJ45 Ports
In the second example, the switch is connected by fiber to a third-party fiber switch, media converter, or other 1000Base-X fiber equipment. The unit works as a compact remote access switch, adding multiple Gigabit copper ports where only a single fiber connection is available.
This application is useful when an existing fiber device provides only one connection point, but several local Ethernet devices still need to be connected nearby. It helps simplify installation and reduces the need for extra switching equipment.

FAQ
Which Fiber Module Should I Choose for this mini switch / media converter?
Compatible with any Gigabit (1.25G) SFP module—supports all wavelengths, fiber modes (single-mode, multimode), and connector types.
I plan to use it as a standalone unit – what should I watch for?
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
What is the most common fault if the converter does not come up?
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
Can I use this as a replacement for Verizon FiOS, Google Fiber, or other ISP fiber services CPE?
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.
