These high bandwidth multi-mode optoelectronic converters are designed to measure optical communication signals in conjunction with a real-time oscilloscope from Lico. The SDAIII CompleteLinQ serial signal analysis software can be used to evaluate the physical layer characteristics of optical signals, such as jitter, noise, and crosstalk. It also includes template testing, serial triggering and decoding, as well as other consistency and debugging tools. The maximum support for serial optical signals is 12.5 Gb/s, and with the help of a reference receiver, it can support>11.317 Gb/s.
