eks Engel presents x-light, an optical bypass that supports all Ethernet based protocols as well as all fieldbusses and various interfaces such as RS485. The device has two duplex inputs and outputs for different types of fibers and con-nectors. In case of failures, it ensures the permanent data transmission in bus or line topologies. Thanks to an optical relay, the signals at the input in question are not transmitted to the corresponding output but to the second input so that the data communication is still working even in case of multiple points of failure. The threshold level that activates the bypass function can be adjusted within a voltage range of 10 to 64 VDC. The delay in which this function is switched off again can be adjusted stepwise to up to 40 seconds. Furthermore, the system can be controlled flexibly via the trigger input, e.g. in case of service or failures.
x-light uses data rates of up to 10Gbit/s and is available for multimode and singlemode fibers as well as for ST, SC or LC connectors. The attenuation is only 1.6 dB and the power supply (10-64 VDC) is redundant.
The optical bypass can be used within a temperature range of -30°C to +70°C. Its housing which is suitable for either DIN rail or wall mount consists of powder coated stainless steel and its dimensions are 115 x 61 x 113 mm. The LEDs at the front show the power supply and network status.
