Product Bulletin PB 1068AG Optical Bypass Relay OBR40 from Hirschmann™ With the new optical bypass relay OBR40, Ethernet fiber-optic networks remain operational even if one or more of the switches suffers a power outage. This protection against multiple faults makes it possible to further increase the availability of Ethernet networks. • The network remains operational even Applications An Internal Switchover when one or more of the switches Mechanism Ensures that Data The advantages of this optical bypass relay suffers a power outage Communications Between are especially valuable for applications in which Neighboring Switches are • The bypass function is guaranteed even parts of the system can operate autonomously. Unaffected. This Mechanism when the relay itself is without power In the event of a local malfunction, data Functions Independently of connections to the unaffected parts are • The ability to schedule the bridging of maintained so that they can remain fully the Data Rate or Protocol. system components opens up new productive. But high-availability data possibilities for maintenance and communication is just one aspect – this relay servicing can do far more than that. In wind parks for example: when the wind gets too strong or The OBR40 robust optical bypass relay, which when maintenance work is needed, one or can be rail-mounted, makes linear or ring more turbines can easily be taken out of the topology fiber-optic Ethernet networks even network without affecting the connections of more reliable. All you have to do is connect it the remainder. to the uplink ports of a switch. If the supply voltage fails, the bypass function is activated Your Benefits and the switch is bypassed, and it is also If network availability is your top priority, possible to use a control contact to trigger the OBR40 optical bypass relay is the perfect the function at will. A stepwise adjustable solution. Even if the power fails simultaneously delay ensures that a previously bridged switch on a number of switches, only the directly is smoothly returned to the network when the affected applications will go down, the problem has been resolved: the boot process remainder of your network – and the major is completed and incoming data packets are part of your processes – will still be available. dealt with immediately. If a number of switches You can rely on this even when the OBR40 are each provided with their own “bodyguard,” itself is receiving no power, because the bypass the Ethernet network can survive even multiple function is effectively activated automatically. failures caused by power outages. Be Certain with Belden Optical Bypass Relay OBR40 from Hirschmann™ The OBR40 optical bypass relay enables you to protect Ethernet fiber-optic networks against power outages at one or more switches. It comes with two duplex inputs and outputs that are available for three different types of fiber (multimode 62.5/125 µm, multimode 50/125 µm and single mode 9/125 µm). It is also possible to use a control contact to trigger the function at will. A stepwise configurable delay, for intervals up to 75 s, provides for the smooth restarting of switches. This ensures that the switch’s boot process can be completed so that incoming data packets can be dealt with immediately. The OBR40 is also remarkable for offering protection rating IP30, an operating temperature range from -40°C to +70°C, and a redundant 24 V DC power supply. LEDS on the front panel indicate the device and network status. Benefits at a Glance • Ethernet fiber-optic networks remain functional in spite of power failures at one or more switches • Switchover threshold for the supply voltage monitor can be adjusted between 10 V and 60 V • The bypass function is activated even if the OBR40 itself has no power • 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 differ ent types of fiber This data-transparent (multimode 62.5/125 µm, multimode 50/125 µm, single-mode 9/125 µm) optical bypass relay • Protection rating IP30 • Potential-free signal contact protects applications • Extended operating temperature range from -40°C to +70°C against multiple failures • Redundant 24 V DC power supply • LED displays for network status and power supply and is suitable for all • Rail-mounted data protocols and rates. • Ideally suitable for all Industrial Ethernet switches from Hirschmann™ Without Optical Bypass Relay Power loss to a switch causes network communication to go down!
