Optical encoder provides over 10 million cycles Product News 12/2/2004 Post a comment Elma Electronic is offering an all-optical encoder that boasts a rotational life of more than 10 million rotations thanks to no mechanical contacts as well as the use of infrared LEDs for signal generation, and a proprietary magnetic system for indexing. The E50 encoders are used in military, medical, industrial, and other mission-critical applications where long rotational life and precision signal generation are critical.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
