The Agilent 86116B represents one of the fastest solutions available for measuring high-speed communication signals. This module has 65 GHz optical and 80 GHz electrical bandwidth, and is identical to the 86116C, but does not include an optical reference receiver.
65 GHz optical channel for 9/125 fibers
1480-1620 nm wavelength range
Characteristic rms noise: 50 uW (55 GHz BW / best sensitivity), 140 uW (65 GHz BW / best pulse fidelity)
Maximum displayed peak power: 40 mW
80 GHz electrical channel with 1.85 mm male input
Characteristic rms noise: 0.5 mV (30 GHz BW / best sensitivity), 1.1 mV (80 GHz BW / best pulse fidelity)
