OZD Profi 12M G22 Fiber Optic Repeater

Extend the range and improve the availability of PROFIBUS networks with this fiber optic repeater.

This PROFIBUS fiber optic repeater from Hirschmann combines two copper and two fiber optic ports with fast ring redundancy for very reliable, high-speed fieldbus communications.

OZD 12 Profi 12M G22
  • Communicate over longer distances – expand PROFIBUS networks by converting signals from two copper segments to magnified long distance fiber optic signals
  • Guaranteed reliability – in case of a transmission fault, integrated ring redundancy automatically switches the signal over to another ring segment without interruption
  • Robust metal housing – increased EMC-resilience, plus conformal coating, ensure data integrity even in harsh environments

Technical Information

Your Benefits

The OZD Profi 12M G22 repeater has two electrical and two optical ports, allowing you to extend the range of your PROFIBUS networks. Its optical signal quality is easy to monitor thanks to informative LEDs on the device itself and signal strength outputs that can be integrated into the process control system.

This fiber optic repeater plays an important role in assuring high network availability. With integrated ring redundancy, it automatically switches a signal transmission over to another ring segment in case of faults, such as a fiber break, without any measurable interruption, i.e., within 0 milliseconds.

With data transfer rates of up to 12 Mbps, the OZD Profi 12M G22 repeater is also amongst the fastest in the world.

Hirschmann OZD Profi 12M G22 Fiber Optic Repeater

The OZD Profi 12M G22 fiber optic repeater is designed for high availability PROFIBUS networks. It extends two electrical PROFIBUS network segments using fiber optic cables and provides seamless redundancy against fiber breaks.

This PROFIBUS fiber optic repeater is ideal for use in real-time control networks that extend across long distances. It is used in power applications, such as oil and gas production or pipelines, and in the transportation industry in highway traffic control systems.

Other uses include water and wastewater systems and manufacturing systems that require large PROFIBUS communication networks with high performance, reliability and data integrity equirements.
