Optical Bypass Relay OBR40

If network availability is your top priority, the OBR40 optical bypass relay is the perfect solution. Even if the power fails simultaneously on a number of switches, your network, with the exception of the directly affected applications, will continue to be available. The table below will help in narrowing your selection to find the right fiber optic relay for your systems.

Benefits

  • The network remains operational even when one or more of the switches suffers a power outage
  • The bypass function is guaranteed even when the relay itself is without power
  • The ability to schedule the bridging of system components opens up new possibilities for maintenance and servicing
  • A control contact can be used to trigger the bypass function at will
  • Stepwise adjustable delay guarantees smooth reactivation of switches

Features

  • Two duplex inputs and outputs which are available for three different types of fiber
    • Multimode 62.5/125 μm
    • Multimode 50/125 μm
    • Singlemode 9/125 μm
  • Protection rating IP30
  • Potential-free signal contact
  • Extended operating temperature range -40°C to +70°C
  • DIN rail mechanism
  • Redundant 24V DC power supply
  • LED displays for network status and power supply

Benefits

The OBR40 robust optical bypass relay, which can be rail-mounted, makes linear or ring topology fiber-optic Ethernet networks even more reliable. All you have to do is connect it to the uplink ports of a switch. If the supply voltage fails, the bypass function is activated and the switch is bypassed. It is also possible to use a control contact to trigger the function at will. A stepwise adjustable delay ensures that a previously bridged switch is smoothly returned to the network when the problem has been resolved: the boot process is completed and incoming data packets are dealt with immediately. If a number of switches are each provided with their own “bodyguard,” the Ethernet network can survive even multiple failures caused by power outages.

Applications

The advantages of this optical bypass relay are especially valuable for applications in which parts of the system can operate autonomously. In the event of a local malfunction, data connections to the unaffected parts are maintained so that they can remain fully productive. But high-availability data communication is just one aspect â€, this relay can do far more than that. In wind parks for example: when the wind gets too strong or when maintenance work is needed, one or more turbines can easily be taken out of the network without affecting the connections of the remainder.

  • A control contact can be used to trigger the bypass function at will
  • Stepwise adjustable delay guarantees smooth reactivation of switches
  • Flexible in use, thanks to connections for different types of fiber
  • Protection rating IP30
  • Potential-free signal contact
  • Extended operating temperature range from -40°C to +70°C
  • Redundant 24V DC power supply
  • LED displays for network status and power supply
