Quadrature Amplitude Milestone

Quadrature Amplitude Modulation (QAM) is the foundation for the delivery of all of cable's digital services. One of the pioneers in headend QAM technology, Vecima Networks Inc. (Toronto: VCM), crossed a major milestone in the category at the end of July. (See Vecima Gears Up Milestones.)

Vecima, once known as VCom and WaveCom Electronics, announced it has sold more than 100,000 QAM modulator channels and over 200,000 cable modem termination system (CMTS) upconverter modules. Nice work over the last decade.

The news comes as everyone and their brother is pushing next-generation edge QAM products for MSOs. These "universal" edge QAMs are designed to support both digital video and Docsis data services, bridging cable's legacy delivery silos. (See Universal Edge QAM Market Heats Up.)

Vecima has its own solution, called HyperQAM. (See Vecima Launches HyperQAM.)

During last week's earnings call, Arris Group Inc. (Nasdaq: ARRS) said its D5 universal edge QAM product is gaining traction with Comcast Corp. (Nasdaq: CMCSA, CMCSK). (See Comcast Taps Arris for Edge QAM Initiative .)

The race is on. Will Vecima withstand the onslaught and ship another 100,000 QAM channels?
