High-Speed Coherent Optical Transmission Characterization
应用文章
Overview
Latest developments in 100 G+ Coherent Optical Transmission Systems and Sub-Systems require more and more flexibility to generate clean modulated signals as well as distorted test signals. The M8195A Arbitrary Waveform Generator gives you the versatility to create the signals you need for dual polarization digital coherent transmission (BPSK, QPSK, PAM4, QAM16, … QAM256, …), Orthogonal Frequency Division Multiplexing (OFDM), Time Domain Pulse Shaping and more with data rates of 32 GBaud and beyond.
Furthermore you can add linear and non-linear impairments to your signal or compensate for distortions between the AWG and the system under test or even components inside your system.
The Keysight M8195A offers sample rates of up to 65GSa/s with 20 GHz bandwidth and up to 4 channels - simultaneously in one single AXIe module.
This is the first application note in a series of application notes to demonstrate Keysight’s latest AWG technology in the M8195A as digital modulation source for electrical and electro-optical components.
