NO RATINGS
Having been involved with the investment industry in another life, I'm particularly happy when announcements involve increased investments. Given the past several years of a barren IPO market, it's a good sign.

I couldn't have said it any better myself .... this is a growing market which hopes to make incandescent light & its heat generation obsolete. Efficiency & cost savings are everybody's objectives and LEDs are the obvious solution at the moment.

LEDs are the obvious evolution of the lighting market (in general) for exactly the same reasons as transistors replaced the venerable electro-mechanical vacuum tubes. Big increase in efficiency, big reduction is waste heat and all the headaches it brings with it, big improvement in shock tolerance, and orders of magnitude longer lifespans. Honestly, it's hard to imagine why investment would NOT go to LEDs. Just like it's hard to imagine what the electronics industry would have been today, had the luddites insisted we stick with vacuum tubes!

LATEST ARCHIVED BROADCAST
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.
