zNID GPON 2301


DZS’ indoor residential GPON ONTs are designed to deliver a full range of advanced IP voice, data and video services over an all-optical broadband access network. and provide a lower cost alternative to outdoor ONT solutions. The Model 2301 GPON ONT provides many features in the smallest possible CPE package, including QoS and multicast video support.

The 2301 ONT features a 10/100/1000Mbps auto-sensing LAN Port in a stylish yet compact enclosure for indoor use. The 2301 ONT may be wall mounted inside the home or placed free-standing on a desktop, and can be equipped with a battery-backup system if necessary.

The 2301 ONT is ideal for FTTH or small business deployments in bridging-only applications where high-speed data must be transported reliably. The 2301 ONT also operates well in conjunction with separate RG devices such as routers and WiFi access points to provide flexible triple-play configurations.

This ONT model includes an On/Off switch conveniently located near the DC power connector. Dying-Gasp support alerts the network operator of removal of power, helpful for problem identification in areas served by the public.

Compliant with standard OMCI definitions, the 2301 ONT is manageable at remote sites and supports the full range FCAPS functions including supervision, monitoring and maintenance.

DZS provides the complete PON solution: ONTs, OLTs, optical splitters, BBUs, EDFAs, RF Transmitters, cabinet solutions and management systems are available from DZS allowing our customers to buy a complete and fully tested solution from one trusted source.
