The South African Radio Astronomy Observatory required a high performance fiber optic Antenna Remoting solution

Tel Aviv – June 10, 2020 | RFOptic Ltd, a leading provider of RF over Fiber (RFoF) and Optical Delay Line (ODL) solutions, and Accutronics (Pty) Ltd, a major supplier of electronic communications equipment to the South African communications, broadcast, and military industries, announced today that they have won a tender issued by the South African Radio Astronomy Observatory (SARAO) for the supply of broadband 18 GHz fiber optic links, for use at their Hartebeesthoek Radio Astronomy Observatory (HartRAO) site to be used on their new Very Long Baseline Interferometry Global Observing System (VGOS) radio telescope.

Accutronics offered with its tender submission the 18 GHz HSFDR (High Spurious Free Dynamic Range) links manufactured by RFOptic.

“HartRAO required an Antenna Remoting solution that allows for the transmission of RF signals with a frequency range from 1 to 18 GHz over fiber while maintaining low spurious levels and excellent linearity”, explained Mr. Tobie Muller, owner of Accutronics (Pty) Ltd. “As their distributor in the region and with a solution that exceeds the requirement specifications, the logical choice was to offer the 18GHz HSFDR solution from RFOptic.”

A high spurious-free dynamic range (SFDR) is desirable when multiple signals of very different power levels are expected to coexist. The high SFDR RFoF solution simplifies signal conditioning requirements that are required to avoid signal saturation and related complications including ALC and power range switching with attenuators or gain blocks.

Dr. Avner Sharon, CEO & CTO at RFOptic, added: “We are proud to have won this important tender together. It underlines the professionalism of Accutronics and the technology of RFOptic. Our high spurious-free dynamic range (SFDR) solution provides the best cost performance, has a high SFDR of 113 dB/Hz and a spurious level of less than -95dBm. Additionally, it offers excellent phase noise, phase linearity, and gain flatness. It can also be supplied in a variety of indoor and outdoor enclosures, thus offering great versatility.”
