Providing optical conversion units, amplifiers, and attenuators for use in optical relay systems, as well as coaxial filters and combiners for onboard radio equipment!
We would like to introduce a case where "SCM for train radio, optical transmission, and shared devices for onboard radio equipment" were implemented in transportation wireless equipment. In wireless systems that facilitate communication between trains and the operations command center, there is the LCX (leaky coaxial cable) communication method as a means of communicating with moving trains. The optical relay system converts radio signals into optical signals for transmission, relaying between the optical master station and optical sub-stations. Our company provides optical conversion units, amplifiers, attenuators for use in the optical relay system, as well as coaxial filters and shared devices for onboard radio equipment. [Case Overview] ■ Implementation Location: Public Social Infrastructure (Transportation Wireless Equipment) ■ Implemented Products: SCM for Train Radio, Optical Transmission, Shared Devices for Onboard Radio Equipment *For more details, please refer to the related links or feel free to contact us.

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.
