Overview
The NEC OD-8550-DFAM is a fixed fiber optic attenuator engineered for precision signal management in 850nm optical networks. This compact, in-line attenuator features an integrated 10dB attenuation value that reduces optical signal power in a controlled, repeatable manner. With dual LC connectors, the OD-8550-DFAM integrates seamlessly into existing multimode fiber installations, making it ideal for laboratory testing, system calibration, and production network environments where signal levels must be optimized for receiver sensitivity and dynamic range.
