Where to Buy RF over Fiber Systems

Cycle has the fully automated WAVE TIMING LINK for RF over fiber with the lowest timing jitter and drift in the market. It can be used for precise transfer and distribution of high-quality RF clock signals to remote locations, which can be even tens of kilometers away. It is actively stabilized and compensates any changes of optical path length caused e.g. by temperature variations.

Cycle also offers the high precision PULSE timing distribution system (TDS), which enables sub-femtosecond distribution of timing signals to remote locations. It takes advantage of the inherently low noise pulse trains of a mode-locked laser (i.e. optical master oscillator, or OMO in short) and uses it as its timing signal which can be referenced to an optical or RF clock. The carefully selected OMO timing signal is transferred through fiber-optic timing links to multiple end stations where transmission delays are detected with attosecond resolution using Cycle’s patented balanced optical cross-correlators (BOC) and actively compensated.

APIC's full product line is designed for high fidelity analog/RF signal transmission over single mode fiber (SMF). In addition to analog signals, APIC's direct modulated lasers (DML) is capable of transmitting high modulation digital signals such as 64 QAM LTE signals for fronthaul transport of 3G/4G/5G communications.
