Features:
- One RJ45 port converts 10/100 Mbit/s copper Ethernet to 100 Mbit/s single-mode fiber.
- The BFOC optical interface supports the documented single-mode path up to 26 km.
- Redundant 24 V DC inputs, LED diagnostics, and a signaling contact support monitored operation.
Siemens 6GK5101-1BC00-2AA3 bridges a copper Industrial Ethernet segment and a long-distance single-mode optical segment without managed-switch configuration.
The RJ45 and BFOC ports serve different media, while the converter maintains the 100 Mbit/s optical path between the connected network sections.
Power and alarm wiring terminate separately, allowing redundant 24 V DC feeds and the external fault contact to be checked without disturbing the fiber connection.
The Siemens 6GK5101-1BC00-2AA3 SCALANCE X101-1LD Unmanaged Media Converter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the two media paths connect
- Copper side: One RJ45 interface connects a 10 or 100 Mbit/s Ethernet device or network segment.
- Optical side: One BFOC interface carries the converted link over 100 Mbit/s single-mode fiber.
- Distance: The documented single-mode optical path extends to 26 km when the specified fiber link conditions are met.
- Media check: Connector type, fiber mode, and the speed of both connected Ethernet devices must be checked together.
Supply path and terminal organization
- Input range: The converter accepts 24 V DC through its documented 18 to 32 V DC operating range.
- Dual feed: The four-pole terminal provides separate entries for the redundant supply arrangement.
- Power demand: Maximum current consumption is 0.12 A and power loss at 24 V DC is 3 W.
- Supply review: Verify both feeds, polarity, protection, and common reference before evaluating link diagnostics.
Local and remote status paths
- Local indication: Front LEDs provide the converter's visible diagnostic status at the cabinet.
- Remote contact: A separate two-pole terminal block connects the external fault-signaling contact.
- Set control: The set pushbutton belongs to the documented fault-signaling function and should be handled according to the installed alarm logic.
- Troubleshooting order: Check power, copper link, fiber path, LEDs, and contact wiring as separate parts of one converter fault.
Cabinet placement limits
- Rail options: The compact housing can mount on a 35 mm DIN rail or an S7-300 rail.
- Wall option: Wall mounting is also documented when the fixing and enclosure arrangement are suitable.
- Enclosure boundary: IP30 protection requires the installation environment to prevent exposure beyond the converter's enclosure rating.
- Operating climate: The installed unit must remain within -10 °C to 60 °C and 95% relative humidity at 25 °C without condensation.
