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.

Equipped with AGC functionality to reduce the effects of fading in the input signal.
The 6GHz band RF signal optical transmission device is a unit capable of transmitting signals in the C and D bands (6,425MHz to 7,125MHz) via optical fiber. It can transmit signals in the C and D bands without channel selection. It is equipped with an AGC function that mitigates the effects of fading in the input signal. By providing one conventional FPU, there is an advantage of reducing the overall system cost by configuring a multi-channel system with this device and a switcher. 【Features】 ○ Wireless transmission bandwidth of 6,425MHz to 7,125MHz (Optional support for 10,250MHz to 10,700MHz band, or both bands) ○ AGC function for fading of RF input signals (AGC ON/OFF function included) ○ Long-distance low-loss transmission of microwave signals via analog optical transmission ○ Wideband BPF at the input to attenuate unwanted radiation outside the band ○ Noise figure comparable to conventional reception sensitivity For more details, please contact us or download the catalog.
You can separate the antenna and the FPU receiver, allowing the FPU receiver to be installed in a convenient location for operation!
The "ROF352" is a device that transmits FPU waves in the 1.2GHz/2.3GHz band via optical transmission. By extending the installation distance between the antenna and the FPU receiver, it is possible to enhance the diversity effect. Additionally, the FPU receiver can be installed in a location that is easy to operate. On the antenna side, power is supplied from the O/E side to the E/O side through an optical camera cable, eliminating the need for power installation work. 【Features】 ■ The installation distance between the antenna and the FPU receiver can be increased - Enhances the diversity effect - Allows for the FPU receiver to be installed in an easily operable location ■ No power installation work required *For more details, please refer to the PDF document or feel free to contact us.
It is possible to extend the transmission distance up to 2 km! Convenient simple waterproof structure for outdoor use!
The "ROF357" is an ROF device that transmits radio microphone signals from 400 to 1300 MHz via optical transmission. By installing it between the antenna and the receiver, it can extend the transmission distance up to 2 km using optical camera cables. The E/O device can output DC for driving an external antenna booster. Designed for outdoor use, the housing has a simple drip-proof structure. 【Features】 ■ Capable of optical transmission of radio microphone signals from 400 to 1300 MHz ■ Can extend the transmission distance up to 2 km using optical camera cables ■ The E/O device can output DC for driving an external antenna booster ■ Power supply can be provided from the O/E device through the optical camera cable, eliminating the need for power installation ■ Designed for outdoor use with a simple drip-proof structure *For more details, please refer to the PDF document or feel free to contact us.
Jointly developed by Kyodo Television and Protech! An optical transmission device capable of long-distance transmission with a single cable.
The "MASTER LINE Series" is an optical transmission device that can handle not only AC input but also DC input, allowing it to be used in various locations without the need for a power outlet. By using optical cables, it enables easy long-distance transmission of 12G/6G/3G/HD/SD signals, intercom, tally, AES/EBU L/R, RS-232/422/485, and even power, all through a single cable. The transmission distance can reach up to 2 km, capable of transmitting 22 channels for large setups and 11 channels for small setups. 【Features】 ■ Long-distance transmission of everything through a single cable ■ AC input/DC input available ■ Asynchronous transmission for each channel ■ Easy identification of connector types through color coding ■ 4-channel camera remote *For more details, please download the PDF or feel free to contact us.
