DZS H665 ONTh665


The H665 is Optical Network Terminal (ONT) compliant with ITU-T G.984 standard. DZS has developed H665 for all clients on the basis of Gigabit Passive Optical Network (GPON) technology. GPON technology supports upstream 1.25Gbps and downstream 2.5Gbps data transmission rate. With DZS’s leading-edge GPON technology, users can enjoy bandwidth-consuming multimedia services such as real-time video, audio and gaming much easier and faster than ever before.

The H665 is comprised of one GPON uplink port and one Gigabit Ethernet downlink port supporting 10/100/1000Base-T (RJ45). The H665 supports high speed internet access service.

The H665 contains both built-in wire-speed L2 switch and L3 routing gateway with port forwarding, NAT and NAPT address translation, multiple PPPoE clients support for high speed internet service.

Service Scenario for PON


A PON consists of an Optical Line Termination (OLT) located at the Central Office and a set of Multi Dwelling Units (MDUs) or Optical Network Terminals (ONTs) located at the customer’s premises. Between them is the optical distribution network (ODN) comprised of fibers and passive optical splitters or couplers. A splitter is a device that divides an optical signal into two or more signals. The OLT connects the PON to the IP network that controls and manages the PON clients. An MDU (ONT) connects the user-specific network to the PON. The ONT can be utilized by a single subscriber or used as a multi-dwelling gateway for a local network.


H665 is a GPON ONT that can be used for a wide range of enterprise solutions for business as well as home. GPON technology supports 2.5Gbps downlink and 1.25Gbps uplink data rate. With the H665, users can easily and quickly enjoy bandwidth-intensive multimedia services such as real-time video, audio, and games.

The H665 provides one GPON port for configuring a GPON network, and provides one 10/100 / 1000Base-T Gigabit Ethernet port.
