50-3000MHz RF optical fiber transmission module

The RFOF-50/3G-G15 radio frequency optical fiber transmission module includes a remote transmitter (Tx) and a near-end receiver (Rx). The working principle is: connect the radio frequency signal to the radio frequency interface of the remote transmitter, convert it into an optical fiber signal through the internal circuit, connect it to the optical fiber interface of the near-end receiver through the optical fiber line, and then convert it into a radio frequency signal through the internal circuit. After amplification, it is output by the radio frequency interface for use by subsequent equipment. This product uses standard low-reflection FC/APC optical connectors, the receiver uses high-performance InGaAs photodiodes, and the transmitter uses high-performance DFB lasers with an operating wavelength of 1310nm and automatic power control (APC) to achieve optimal optical power stability within the entire operating temperature range. It has the characteristics of wide working frequency, high gain, long transmission distance, stable performance, simple installation and high cost performance.

Product Introduction

◆The ultra-wide working frequency band covers common radio frequency bands such as FM, VHF/UHF, and L, and is suitable for 2G/3G/4G, WiFi, radar, navigation and other signals.

◆Extremely low transmission loss, long-distance transmission capability, single-mode optical fiber loss is about 0.2-0.4dB/km, far better than coaxial RF coaxial cable, and 10-20km non-relay transmission can still maintain a high signal-to-noise ratio.

◆Anti-electromagnetic interference, static electricity, wireless signals and industrial electromagnetic interference have little impact on it. It is suitable for high-interference environments such as base stations, computer rooms, radars, ships, and military industries.

◆Small in size and flexible in application, it can transmit signals one-to-one or one-to-many, making it easy to install and deploy.

Application Scope

It can be used for long-distance transmission of radio frequency signals in FM, VHF/UHF, 433M, walkie-talkies, 2.4G Wifi, radar, satellite communications, 2G/3G/4G LTE, LoRa and other frequency bands, radar antenna remoteness, radio signal monitoring, and microwave signal transmission coverage. It solves the problem of serious signal attenuation caused by too long cables in ordinary radio frequency cables, and can transmit signals to places ranging from several meters to several kilometers, or even dozens of kilometers away.
