  • WiFi 6 (11ax)
  • Remote management
  • OPAL platform

WiFi 6 (11ax) technology for superior performance and coverage

The Zyxel PX7511-B0 features WiFi 6 (11ax) technology to provide an ultimate solution for both speed and coverage. With WiFi 6 (11ax) high-efficiency wireless support, the maximum wireless data rates can achieve 6000 Mbps, while the MU-MIMO and OFDMA features support reliable wireless connections for high-speed data and multimedia applications. It significantly reduces dead zones in homes, solves the high-density issues, supports the latest high-throughput features and low-latency applications in order to help service providers to achieve better customer satisfaction.

Uplink MU-MIMO


Integrated internet services through fiber

The Zyxel PX7511-B0 supports 10 Gbps symmetric speed with XGS-PON fiber WAN connection and a 10GbE LAN. The product smoothly migrates from today’s GPON deployments to the next-generation 10G symmetric and asymmetric PON solutions.


TR-069 remote management

The Zyxel PX7511-B0 supports TR-069 that simplifies remote configurations, upgrades as well as management to improve cost-effectiveness and customer satisfaction. Additional support to the latest TR-181 issue-2 data model also enhances service providers’ visibility on subscriber LAN networks for improved customer assistance.


Zyxel OPAL for better flexibility and faster time to market

With the same OPAL firmware trunk applied in the Zyxel CPE, the PX7511-B0 inherits a rich, field-proven feature set such as TR-069, VoIP and more. Service providers can expect the same user experience when migrating to new devices. Moreover, the lab qualification time can be greatly reduced with the same OPAL firmware trunk. As a flexible software platform, OPAL offers a modular software architecture and open framework that provides the flexibility for easy feature tailoring to assure smooth resolution of all the application requests.
