SIGNAL POWER CONTROL SYSTEM FOR FIBER OPTIC COMMUNICATION SYSTEMS.

摘要

A signal power control system for fiber optic communications systems is disclosed herein. The invention is adapted for use in a system including a transmitter (760), a receiver (440), an optic fiber (160) therebetween, and bobbin means (180) for dispensing the fiber. The invention includes means (480) for detecting the power of the signal delivered to the receiver (440) from the transmitter (760) and for producing a control signal which varies in response to the detected signal power level. Means for providing the control signal to power control means (740) are included. The power control means (740) is responsive to the control signal and operates to vary the output power of the transmitter (760) as necessary to accommodate the dynamic range of the receiver (440).
