Features:
- This optical link module bridges one RS485 PROFIBUS segment with two glass-fiber communication paths.
- The two optical interfaces use four BFOC sockets and a 1310 nm single-mode transmission wavelength.
- The documented optical distance reaches 15 km with the specified glass-fiber cable and attenuation conditions.
At the electrical side, the module accepts the PROFIBUS segment through its 9-pin Sub-D RS485 connection and transfers the communication signal to the optical branches.
The two fiber interfaces form the outgoing glass-fiber paths; BFOC connector selection and the single-mode cable type must match the installed network route.
Network setup should retain the documented transfer-rate range and confirm the supply and signaling-contact wiring before the OLM is introduced into the segment.
The Siemens 6GK1503-3CC00 PROFIBUS OLM/G12-1300 V4.0 Optical Link Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Electrical-to-Optical Path
- Segment input: One 9-pin Sub-D connector receives the RS485 PROFIBUS segment.
- Optical conversion: The module converts the electrical segment into glass-fiber transmission paths.
- Fiber branches: Two fiber-optic interfaces provide the optical side of the link.
- Test point: A two-pole terminal block is provided for the documented test connection.
Optical Connection Details
- Connector form: Four BFOC sockets are provided for the two optical interfaces.
- Optical mode: Transmission uses a 1310 nm single-mode optical wavelength.
- Link distance: The stated glass-fiber length reaches 15 km under the specified cable and attenuation conditions.
- Cable selection: Use the documented 10/125 µm or 9/125 µm glass FOC types for that distance condition.
PROFIBUS Parameters
- Transfer range: PROFIBUS communication is documented from 9.6 kbit/s to 12 Mbit/s.
- PA setting: The stated PROFIBUS PA transfer rate is 45.45 kbit/s.
- Segment match: Set the optical link according to the installed RS485 segment and network speed.
- Topology check: Confirm the BFOC paths and fiber type before connecting the network branches.
Supply and Indication
- Power range: The OLM operates from 18.8 to 28.8 V DC through its 24 V DC supply input.
