Networks of 100 and 400 Gbps rely on multiple-lane transmitters based on 25 Gbps class lasers. As these technologies become mainstream and transition to high-volume manufacturing, there is a growing need for test systems that provide high accuracy at a low cost.
Of interest to those involved in telecom R&D and manufacturing, as well as network operators that need to perform compliance testing, Keysight Technologies released the N1092A, N1092B and N1092D DCA-M sampling oscilloscopes, which are ideal for 25/100/400 Gbps optical test.
The N1092X DCA-M is a sampling oscilloscope family designed specifically to perform compliance tests quickly and accurately. New low-noise, low-jitter technology allows measurement of low-power, high data rate NRZ and PAM-4 devices. The instruments’ FlexDCA user interface is identical to that used in the industry-standard 86100D DCA-X sampling oscilloscope, allowing a drop-in replacement for existing test systems, but with substantially faster throughput, a much smaller footprint and more than double the sensitivity.
The low-cost N1092X Series is available in three model numbers to fit a variety of applications and budgets. The N1092A has one optical channel, the N1092B has two optical channels and the N1092D has four optical channels. Channels have calibrated reference receivers for industry-standard compliance test from 20 to 28 Gbps rates, and are compatible with single-mode and multimode fibres and wavelengths.
