ABSTRACT:
A fiber optic connector module includes a beam splitter for directing 10 percent of a fiber optic signal to a monitor connector. The input of the beam splitter is passed through a variable attenuator. By monitoring at the monitor connector, the variable attenuator can be adjusted utilizing the known split ratio of the beam splitter to achieve a desired dynamic range of the optical signal leaving the module.
