MFLC is a compact, modular wideband optical link enabling up to four RF channels to be transmitted over a single CWDM fiber. A central mainboard accepts up to four plug-in boards (TX or RX) in any mix. It provides RF/optical power monitoring, optical power compensation, high IIP3 immunity, remote Ethernet 10/100 Base-T control, and a backed-up real-time clock with RAM to log RF levels and service data. Dual 10–28 V DC input supports remote, waterproof-case integration.
