Global revenue for broadband access equipment increased 3 percent YoY, reaching $3.2 billion, says the new report from Dell’Oro Group.

XGS-PON OLTs witnessed an 874 percent YoY increase in XGS-PON OLTs and the continued growth of DOCSIS 3.1 CPE offset CCAP spending declines, the report said.

Earlier in July, the agency had revealed that spending on cable infrastructure will only reach $1.6 B by 2023, as cable operators slow their Converged Cable Access Platform (CCAP) purchases while focusing on their Distributed Access Architecture (DAA) deployments.

“The transition to 10 Gbps fiber technologies is now a global phenomenon,” said Jeff Heynen, research director, Broadband Access and Home Networking. “The strength of 10 Gbps EPON and XGS-PON equipment in the quarter helped to offset continued weakness in cable CCAP spending, as major multiple-system operators’ focus on deploying purchased capacity.”

The report highlights that total DSL port shipments increased 3 percent YoY, with VDSL Profile 35b ports increasing 29 percent, and Gfast ports increasing 42 percent.

Total cable access concentrator revenue decreased 40 percent YoY to $237 million, driven once again by a slowdown in CCAP license purchases in North America.

Dell’Oro Group  forecast that global PON equipment market revenue will reach $7.3 B by 2023, driven by spending on new 10 Gbps EPON and XGS-PON deployments, and on maximizing existing 2.5 Gbps GPON networks.

Telecom operators and ISPs are focusing on XGS-PON for the next-generation deployments, the research firm said.
