ADTRAN, Inc. (NASDAQ:ADTN) has unveiled the ADTRAN SDX 621X, a 10G PON residential optical network terminal (ONT). The XGS-PON residential ONT complements the company’s existing 10G PON business ONTs. ADTRAN says the ONT’s “flexible optics approach” enables operators to use the same PON infrastructure to serve fiber-to-the-home (FTTH) subscribers, higher-bandwidth business customers, and 4G/5G “anyhaul” services requirements.
“The original use cases for 10G PON focused on multi-gigabit enterprise and infrastructure backhaul services, given the high costs of 10G PON ONT optics,” Ovum Principal Analyst Julie Kunstler explained via an ADTRAN press release. “Technical innovation, as seen within the ADTRAN 10G PON solution, along with economies of scale spurred by 10G deployments globally, are driving down the cost difference between GPON and 10G. Consequently, 10G PON is now a viable option for residential subscriber deployments, and operators understand the competitive and future-proofing benefits of moving to 10G.”
Those benefits include support of the capacity that emerging requirements such as high-resolution 360º video, autonomous vehicles, and fully immersive applications will require, says ADTRAN. The company expects such service demands to outstrip current 1-Gbps connections, particularly as operators look to converge multiple services onto a single infrastructure.
