The HP / Agilent 86106B is a 28 GHz optical / 40 GHz electrical module, 1000-1600 nm (SMF only). It has an integrated, calibrated optical channel with a built-in OC-192/STM-64 filter that can be switched in for a standards-base transmitter compliance test. When the filter is switched out, the 86106B offers 28 GHz of unfiltered optical bandwidth for accurate characterization of high-speed lasers. The frequency-response variation of the unfiltered optical channel also has been improved to minimize the distortion on measured optical pulses. A 40 GHz electrical channel is available for wide-bandwidth measurements on electrical waveforms. Features Optical channel specifications: Bandwidth: 28 GHz Wavelength range: 1000-1600 nm Characteristic rms noise: 13 µW (filtered) 23 µW (unfiltered) Maximum average input power: 2 mW Fiber input: 9/125 µm Reference receiver capability (9.953/10.3125/10.664/10.709 Gb/s) Electrical channel specifications: Bandwidth: 18 and 40 GHz Transition time: 19.5 ps (18 GHz) Characteristic rms noise: 0.25 mV (18 GHz BW), 0.5 mV (40 GHz BW) Maximum input signal: ± 2 Vdc Input: 2.4 mm male
