[Case Study] Optical Link for Satellite Ground Stations

[Case Study] Optical Link for Satellite Ground Stations

Compatible with 19-inch standard racks! Examples of products that are resistant to external noise due to fiber optic transmission.

We would like to introduce a case where a "Optical Link for Satellite Ground Stations" was implemented in satellite ground station equipment. Radio waves from space, such as satellite broadcasting (BS, CS), are received by remote antennas on the ground. The received signals are downconverted (frequency converted) and transmitted as IF signals from the antenna to the station (receiver). The distance between the antenna and the station is several hundred meters to several kilometers, and using coaxial cables results in significant loss, so we use an optical transmission device called "RoF" that employs fiber optics. 【Case Overview】 ■ Implementation Location: Space and Satellite Related (Satellite Ground Station Equipment) ■ Implemented Product: Optical Link for Satellite Ground Stations *For more details, please refer to the related links or feel free to contact us.

[Technical Topics] Introduction to Analog RoF Technology

[Technical Topics] Introduction to Analog RoF Technology

Explaining the "advantages of analog optical transmission" and the "counter performance of E/O and O/E converters compatible with 10MHz to 3GHz"!

Tamagawa Electronics has developed analog optical transmission devices since the second-generation mobile PDC era as a countermeasure against insensitivity, responding to customer needs. In this column, we introduce the analog RoF technology cultivated by our company over many years. RoF stands for Radio over Fiber, which refers to optical fiber wireless. We convert [electricity to light] using an E/O converter, transmit it via optical fiber, and then convert [light to electricity] using an O/E converter to demodulate the electrical signal. We invite you to read on.
