Ongoing Fiber to the Home (FTTH) deployments by carriers in China and Verizon's (NYSE: VZ) ongoing FiOS rollout helped drive almost $800 million in revenues in Q4 2010.
"We estimate that China accounted for more than half of total GPON revenues in the fourth quarter," said Tam Dell'Oro, President of Dell'Oro Group.
Although Chinese service providers leveraged EPON for their initial FTTH deployments, Dell'Oro said that they "have increasingly utilized GPON over the last several quarters," and that "GPON will become the leading PON technology in China within the next few years due to its higher bandwidth capabilities and functionality."
From a vendor perspective, Huawei, Alcatel-Lucent (NYSE: ALU) and Ericsson dominated the top three spots in PON sales. Huawei may still be the dominant PON supplier in China, but they are seeing continual competitive pressure from non-Chinese vendors such as Alcatel-Lucent and Ericsson.
Outside of China, Alcatel-Lucent continues to ride the deployment wave for Verizon's FiOS, which Dell'Oro said accounted "for a significant 15 percent of total GPON revenues."
