Summary

Contrary to conventional wisdom, the rise of telecom video has boosted the demand for RF-modulated optics to transmit broadcasted video signals in both cable HFC (hybrid fiber coax) and FTTx RF overlay networks.

The conventional wisdom these days is everything is going IP, and for that matter everything is going to be transported via Ethernet. It goes almost without saying that the data, voice, or video being sent is in digital form. It's a foregone conclusion and rather unexciting - except for flashy new personalized video services.

So where does that leave a technology that has variously been described as analog and broadcast? In fact, the market for broadcast video over radio frequency (RF)- modulated optics has held steady for years, grown the past few, and even shows signs of accelerating this year.
