VCSELs offer better long distance visibility, clarity
Product News  
7/5/2006   Post a comment
Offering long distance visibility and low power consumption for security camera applications, OPTEK's OPV330 VCSEL series uses lower drive currents to achieve the same power output levels as conventional infrared LEDs.

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.
