OFC Engine
(Optical Frequency Comb Clockwork for OEM integrators)
Performance meets low-SWaP
Menlo Systems’ OFC Engine: A low SWaP (Size, Weight, and Power) clockwork for OEM integrators. The OFC Engine builds on Menlo’s decades-long experience with robust and compact frequency combs. Built upon Menlo's unrivalled figure 9® fiber mode-locked oscillator technology, the OFC engine combines the high performance required for transportable optical atomic clocks and a low-SWaP design.
With a focus on OEM integrators, it is optimized for flawless integration and volume manufacturing. Integration is as easy as it gets: Driving and mode locking electronics as well as pump modules are included. Interfacing is provided for user-generated phase lock loops to lock f rep and fCEO . Ready for deployment.
