- Description
The Siemens 6GK1503-4CB00 is a PROFIBUS OLM/G22 V4.0 optical link module that bridges two RS 485 PROFIBUS segments to two glass fiber-optic BFOC ports, carrying 9.6 kbit/s to 12 Mbit/s (or 45.45 kbit/s for PROFIBUS PA) over standard distances up to 2850 m. It runs on 24 V DC, includes a signaling contact and measuring output, and supports ring redundancy.

Selection Notes
Two RS 485 ports let this OLM sit between two independent PROFIBUS segments or close a fiber ring, unlike the single-electrical-port glass variants that only extend one segment onto fiber. The redundant power input and signaling contact report a supply or link fault to a separate monitoring circuit, which matters when the module sits unattended between two cabinets. Its 2850 m standard glass-fiber distance covers most in-plant runs without stepping up to the single-mode long-distance variant.
Applications
Linking two PROFIBUS segments through a fiber backbone, or forming a fiber ring across a plant where a break in one span must not take the whole network down.
