912-OEO-4R Wavelength Converter

The model 912-OEO-4R is an Optical-Electrical-Optical (OEO) signal converter that provides several functions, including optical wavelength conversion, optical signal boosting, optical multiplexing, and re-clocking of optical outputs to reduce jitter. Although many configurations are possible, the standard card combines optical signals from four separate fibers into a single fiber, often with increased optical power budget to significantly extend the range of the original signals or pass the signals through higher loss cabling systems. The signals are converted back to their original wavelengths at the other end of the fiber link, thus providing a transparent, bidirectional system.

The form-factor and proven reliability of Moog products make the Model 912-OEO-4R ideal for applications such as FPSO (Floating Production, Storage and Offloading) units, optical data and telemetry networks, specialized industrial machines, advanced work class ROVs, tactical and industrial security networks, and armored vehicle platforms.
