Does the PRS switch have an optical port

The PRS-7961 switch does not appear to include a built-in optical (fiber) port.

The PRS-7961 is primarily an industrial Ethernet switch designed for standard copper-based network connections, and its documentation focuses on electrical safety, DC power handling, and general Ethernet operations without mentioning fiber optic interfaces or optical transceivers .

Fiber Connectivity in the Praesideo System

While the PRS-7961 switch itself lacks an optical port, the PRS-FIN, PRS-FINNA, and PRS-FINS fiber interfaces in the Bosch Praesideo system provide optical connectivity. These units convert between plastic optical fiber (POF) and glass optical fiber (GOF), supporting both multi-mode and single-mode fibers depending on the model . They include SC connectors for glass fiber and POF connectors for plastic fiber, along with power and control inputs for network supervision .

• PRS-FIN: Supports multi-mode glass fiber and has two control inputs.
• PRS-FINS: Supports single-mode glass fiber and two control inputs.
• PRS-FINNA: Converts POF to GOF but lacks control inputs and a network node address . These fiber interfaces are used in pairs to extend network distances beyond the 50-meter limit of plastic fiber, but the switch itself does not directly provide an optical port. To integrate fiber connectivity with a PRS-7961 switch, a separate fiber interface like the PRS-FIN series would be required.

Summary

• PRS-7961 switch: No built-in optical port; standard Ethernet connections only.
• Fiber support: Achieved via external PRS-FIN/PRS-FINS/PRS-FINNA interfaces.
• Use case: Fiber interfaces allow long-distance connections and network redundancy, but the switch connects to them via standard Ethernet or plastic fiber links. This means that if your network design requires optical fiber, you will need to use a dedicated fiber interface unit alongside the PRS-7961 switch.
