Engineered, rack-mounted, optical reference unit at 1547.825 nm
Abstract
An engineered optical reference unit at 1547.825 nm which uses the Kr 1s2-2p8 transition was developed. Due to its simple start-up, the unit can be used easily. The absolute frequency stability was measured to be in the order of 100 kHz which is ideally suited for high density WDM systems.
