Replacement & Compatibility FAQ
Q: Is the 6GK1501-1BB00-2AA3 discontinued?
A: This model may have limited availability. The SCALANCE XB101-1 (6GK5101-1BB00-2AA3) is the recommended current-generation replacement.
Q: Can I use a single-mode fiber cable with this converter?
A: No. The 6GK1501-1BB00-2AA3 is designed for multi-mode fiber only. For single-mode, select the 6GK1501-1AA00 variant.
Q: Does this converter require any software configuration?
A: No. It is an unmanaged device — plug-and-play with no IP address or configuration required.
Q: What fiber connector type does this unit use?
A: BFOC (Bayonet Fiber Optic Connector), also known as ST-type connector.
Q: Is this unit compatible with PROFINET?
A: Yes. As a transparent Layer 1 media converter, it is fully compatible with PROFINET IO and any IEEE 802.3 Ethernet protocol.
Q: Can Konmask.com supply the matching fiber patch cable?
