We offer high-performance RF Fiber-Optic Links with operating frequencies beyond 50 GHz. Fiber optic links are useful for long cable runs where the attenuation of conventional copper coaxial cable would be prohibitive. This attenuation can be a significant factor when deploying communication systems in the millimeter-wave frequency range. We also offer Mach-Zender modulators for converting RF into an optical signal for transmission over fiber optic cable.
