HUBER+SUHNER Unveils Copper-free Fiber Link

Precise timing synchronization for high-performance networks is improved with HUBER+SUHNER enhancements to a  copper-free, fiber-powered link. The HUBER+SUHNER Global Navigation Satellite System (GNSS) and power-over-fiber solution bring pre-, during and post-installation benefits to telecommunications providers working in the 5G and data center space.

Using fiber optics as a means of power for the antenna brings cost and timing savings during installation and operation, as no power distribution is needed on a building’s roof.

“As the volume of data and transfer speeds continue to increase, so too does the requirement for accurate time synchronization, with GNSS timing signals in use within many applications, from data centers to central offices,” said product manager Dominik Tibolla at HUBER +SUHNER. “Using the GNSS signal from satellites enables the acquisition of precise and accessible timing information from atomic clocks, whilst combining this with the distribution over fiber, lower attenuation over longer distances is enabled.”

Traditionally, power is carried over copper technology with a GNSS antenna. This often requires a power cable to be attached to the signal distribution cable. The GNSS and power-over-fiber solution from HUBER+SUHNER eliminates the need for a separate power cable by using the fiber optic connection to the antenna as a means of power and signal distribution.

GNSS and power-over-fiber solutions go beyond where existing technology could reach. It enables an increased distance of a few kilometers between the source and receiver system, compared to a few meters previously. Satellite signals cannot usually reach indoor locations due to the blocking effect of the building structure but combining this with fiber distribution internally, the HUBER+SUHNER GNSS and power-over-fiber solution distribute the GNSS signals to all corners of a building interior, providing a more secure, reliable and flexible connection.

Using the fiber as a means of power distribution also offers unlimited safe and secure timing signal reference distribution, with reduced interference. Providers also can take advantage of its ability to make use of existing infrastructure by having to pay onlyfor what is used within the network and being ‘future-proof ready,’ with easy and flexible expansion opportunities.
