PMG5622GA ZYXEL ONU /ONT Dual-Band Wireless AC/N GPON HGU with 4-port GbE LAN and RF Overlay for FTTX GPON System



หมวดหมู่ : FTTx Solutions for Buildings GPONFTTxEquipment


The Zyxel PMG5622GA is a next-generation Dual-band Wireless ONT Home Gateway Unit (HGU) with RF overlay. The PMG5622GA is fully compliant with the GPON ITU-T G.984.x standards and Wireless IEEE 802.11 ac/n to provide ultra-high speed fier access along with 4-ports GbE LAN for wired connectivity, 2-port FXS port for VoIP services, one USB 2.0 port, one coaxial cable output for CATV service in addition to a Wireless LAN with 2x2 11ac and 2x2 11n confiurations. The ultra-thin design minimizes the housing height to 32mm with brushed fiished surface. It not only makes the PMG5622GA an advanced optical terminal Home Gateway Unit, but also a delicate, elegant decoration for the interior space.

In recent years, the demand for broadband bandwidth has been growing dramatically. Since the downstream spectrum is mostly dominated by various video services with DOCSIS technology, only a small portion of bandwidth can be allocated to High-Speed Internet (HSI) services. This makes the per-bit cost to be signifiantly higher in a DOCSIS/Hybrid Fiber Coaxial (HFC) network comparing to GPON networks.

Due to the fact that DOCSIS 3.1 is incompatible with existing DOCSIS 3.0, operators must replace the existing CMTS and modems, rebuild the network for US capacity and reassign license frequency once they decide to migrate to the latest standard. The transition takes a vast amount of cost and time, not to mention service interruptions. On the contrary, the investment for a GPON infrastructure is sustainable for future bandwidth expansions as it can be reused for the next-generation 10 GPON deployments and has better upgradability than DOCSIS 3.1 as well.
