Keysight N7752A Dual Channel Optical Attenuator Power Meter 1260nm to 1640nm High Precision Fiber Optic Test System
Keysight N7752A 2-Channel Optical Attenuator and Power Meter
The Keysight N7752A is a high-performance 2-channel optical attenuator and power meter designed for precision fiber optic testing in transceiver manufacturing and network integration environments. Operating across a wavelength range of 1260nm to 1640nm, the N7752A combines fast attenuation setting, active power control, and accurate optical power measurement into a compact half-width rack unit. With 0.01dB resolution, 20ms settling time, and a built-in InGaAs power meter, it delivers exceptional throughput and measurement accuracy for multi-channel optical component characterization.
