Integrated Internet Services through Fiber with Ultra-High-Speed Data Access

Brings fiber cabling and signals to homes

PMG1005-T20A, a GPON optical network unit with 1-port GbE LAN, is a simple fiber home bridge that provides end users with a high-speed performance experience in a cost-effective way.

Integrated Internet services through fiber

The ZyXEL PMG1005-T20A Single Family Unit (SFU) features ITU-T G.984-compliant GPON port and integrates a one-port 10/100/1000 Mbps Ethernet switch. It is a fiber network edge device offering high-performance and long-reach connection services.

Ultra high-speed for bandwidth-demanding applications

The ZyXEL PMG1005-T20A offers optical fiber technology for telecom carriers to address increasing service demands and to deliver much higher speeds over fiber optic lines.

Advanced QoS for ensured service quality

The ZyXEL PMG1005-T20A come equipped with IP QoS features for service providers to freely design QoS policies and to prioritize mission-critical services - such as IPTV - based on their individual service plans.

ONT Management and Control Interface (OMCI) remote management

Complying with the standard OMCI (G.984.4) between the ONT and OLT, the ZyXEL PMG1005-T20A can be connected to the GPON OLT to support the management and provisioning functions for network operators.
