The Keysight N7764A variable optical attenuator offers exceptional performance at a low price.

Extension of N77xx-series

The N7764A attenuator is an extension to Keysight’s high density N77xx-family that establishes a new standard in space-saving fiberoptic instrumentation.

Features and Benefits

• Compact instrument combines and integrates multiple functions for setting attenuation and power levels and controlling optical power to reduce CAPEX and floor space.
• Fast and precise setting of optical power levels with settling times of 100 ms for improved test throughput.
• Active power control to keep output power constant
• The multichannel attenuator sets and controls several ports at the same time and saves significant time characterizing multiport and multichannel components and network equipment.
• The instrument can be controlled via LAN and USB, as well as GPIB for compatibility with existing equipment.
• An easy-to-use and intuitive graphical user interface speeds up the integration process.

Applications

• Optical transceiver testing
• Optical network integration testing
