Agilent Keysight N7761A Single Channel SingleMode Optical Attenuator FC

The Agilent N7761A is a single-channel variable optical attenuator designed for single-mode fiber (SMF) applications. It’s part of Keysight’s compact N77xx series, known for high-density, space-saving instrumentation. Here’s what makes it a solid performer: Wavelength range: 1200 to 1700 nm Attenuation range: 0 to 60 dB Insertion loss: =1.2 dB Input power: Up to +23 dBm Attenuation speed: 0.1 to 1000 dB/s (selectable) Settling time: 20 ms (attenuation), 100 ms (power) Interfaces: USB, LAN, and GPIB for remote control Form factor: Half-rack width, compact benchtop unit It also supports active power control, allowing you to maintain constant output power—great for automated test setups. The N7761A is compatible with legacy 8157x/8156x software, making integration into existing systems a breeze.
