The SANLAND RFoF-C is a remotely controlled analog RF over fiber link designed to transport RF signals from 5 MHz to 6 GHz over single-mode fiber. One 6G-C TX and one 6G-C RX form a complete point-to-point RF optical link, with 50 Ω SMA interfaces and a 1550 nm FC/APC optical connection.
An internal microcontroller, programmable attenuation and selectable LNA modes allow users to remotely configure link gain for different RF input conditions. Through the RJ45 Ethernet interface, operators can adjust gain and monitor RF level and temperature from a remote computer, reducing the need for on-site maintenance at remote antenna, Satcom, DAS and broadcast locations.
