AirFiber wants to break the perception that SLAs are not possible with free space optics. The AirFiber 5800, a protocol-agnostic product that has up to 1.25 Gbps of total capacity, is a fault-tolerant system to support comparable capacity and quality found in fiber-based products. Incorporating its proprietary “Redundant Link Controller” technology, AirFiber claims carriers can deploy FSO links that are immune to data loss even in the face of link interference. And if interference does occur on one of the links, the RLC can maintain error-free communications by utilizing data supplied via the redundant link. Designed to meet carrier-class requirements, the 5800’s active monitoring and control mechanism automatically adjusts for external environmental disruptions such as rain and building sway.
