The modular X20 hub system was developed for Industrial Ethernet use. Different hub devices can be easily configured from a kit. Hub units with two RJ45 connections are available, which are simply lined up together or added to a bus controller.The new module is a major expansion to the system. Compared to copper wiring running over Fast Ethernet, which can only cover distances up to 100 meters, the new fiber optic module covers distances up to 2,000 meters. The underlying standard is 100Base-FX, based on duplex LC technology. No internal downgrading technology is used, which means there is no loss of performance (wire speed). Therefore, the fiber optic module is optimally suited e.g. for use in the X20 hub system in any POWERLINK topology.For more information, visit B&R Automation at http://www.br-automation.com/.
