The FiberLinX-II solution connects a host/remote network over fiber optics. Building on the success of the original FiberLinX solution, the FiberLinX-II combines media conversion with an advanced-feature set for network management and troubleshooting, including Extra-Tagging and EtherType control functionality. With the FiberLinX-II, administrators can observe the end-points, and the fiber link between them, as single management entities and not as separate elements. Host management traffic is not visible to the remote or customer network nor is access to the customer network required, guaranteeing end-to-end data integrity.
