Product Dimension of RF over Fiber Module GOM25

Description:
GOM25 is a RFoF module operate between 45MHz to 2.5GHz, provide long distance RF signal transport over Single Mode Fiber. It is a RF over fiber system. This module is a photoelectric conversion device designed specifically for long-distance, high fidelity transmission of satellite system RF signals. Solved the core problems of short transmission distance, high loss, and susceptibility to electromagnetic interference in the transmission of high-frequency satellite signals, including Beidou, GPS, Glonass, Galeo and other satellite navigation frequency bands, using traditional coaxial cables. The system consists of a pair of modules, TX unit and RX unit, which transmit remote RF signals to receivers or time-frequency devices tens of kilometers away with low distortion and loss through single-mode optical fibers. It is a key component for achieving high-precision positioning, timing, and synchronization systems to operate stably and reliably in a distributed architecture.

Product Characteristics:
1. Low Power Consumption
2. 5V Power Supply
3. The Total Gain(TX+RX): 20dB
4. Frequency Range: 16~2800MHZ

Applications:
1. GPS and GNSS Repeater Systems
2. Multi-Radio Interconnect
3. 5G testing
