Timing & Frequency over Fiber

Home / Solutions / Timing & Frequency over Fiber

Optical Zonu’s wide array of products offers a capability to distribute Timing and Frequency (RF) signals over single mode or multimode fiber optic cable for various distances. Precise synchronization of clocks is a crucial ingredient of public safety communication systems and private networks. Our RF over Fiber Optics Links are compliant with timing standards such as GPS, Glosnas, Galileo, WWVB, MSF, DCF and etc. They may also carry common reference frequency signals such as 1, 10 and 50 MHz.

Transporting timing and frequency signals over fiber optic cable has distinct advantages. Optical fiber supports very long cable distances, up to 10 Km or more, with minimal signal loss and degradation. Optical fiber operates by transmitting light along a dielectric glass fiber, rather than electrical signals over copper wires.  This provides a highly secure, tamper-proof medium for signal transfer, minimizing security risks and unauthorized signal interception concerns. Light is also unaffected by electro-magnetic interference, allowing signals to be transmitted unaffected through electrically noisy environments.

Optical Zonu’s RF over Fiber Optics Products are suitable for the transport of UHF and VHF signals over fiber optic cable. Our fiber optic Interfacility Links (IFL), available in various form factors, are capable of providing long or short distance uplink/downlink solutions which can be achieved using our cost effective isolated Fabry Perot Lasers, while professional and more demanding long distance or multi-carrier CWDM applications may be met using our high dynamic range, regular or cooled DFB Lasers – delivering excellent signal quality under varying conditions.
