Fiber Time/Frequency Transfer System

Supplier
Sdjiliang
Category
Optical Fibers
Origin
China

The fiber time/frequency transfer system sends time signals to remote users with nearly zero delay and compensates fiber-link delay changes in real time. It also transfers optical-frequency signals stably, compensating link delay and phase noise to maintain phase synchronization. Highly stable, accurate transfer supports comparison, transmission and use of precision time/frequency signals.
