RF Over Fiber Transmission ModuleOptical Media Converter

The Radio frequency over fiber transmission module ROF030TR-B designed for single RF port bidirectional RF/wireless signal transmission over long distance, which overcome the problem of high loss when the RF/wireless signal transmit over coaxial cable or free space. It integrate the transmitter, receiver, and a circulator or a duplexer in one compact package.

Module structure diagram

In addition to adding a circulator at each end to achieve bidirectional functionality, add attenuators in the near-end module, and the remote module adds a power amplifier, so that the output power matches the smart meter and antenna power in your field.

In this way, after passing through the optical module, the wireless power transmitted to the antenna end can reach 500mW.

What is the signal level on Rx and on TX side.
Tx from device is maximum 500mW/27dBm (normally) and minimum 0,01mW/-20dBm (rarely). The devices automatically adjust transmitting power. Rx from antenna side is maximum 5,01mW/7dBm (rarely) but normally range from 0,01mW/-20dBm to 1e-12mW/-120dBm (one pico-watt). Typically Rx power is between -60dBm to -90dBm (0,000001mW to 1e-8mW).）
