DZS H680GM ONTh680gm

Overview

The H680GM optical network terminal is targeted for all subscribers requiring multiple POTS interface, and high-speed data interfaces in a cost-effective indoor housing. Fully compliant with ITU-T G.984 standards, the H680GM supports data rates of 1.25Gbps upstream and 2.5Gbps downstream. With DZS’s leading-edge GPON technology, users can enjoy bandwidth-intensive multimedia services such as real-time audio and gaming much easier and faster than ever before.

The H680GM provides one GPON uplink port, four Gigabit Ethernet (10/100/1000Base-TX) ports, Wireless LAN interface and two FXS voice ports that enhance the ability to deliver demanding data/Wi-Fi/VoIP services. The H680GM uses Session Initiation Protocol (SIP) to terminate VoIP calls so that in-home wiring does not change, and standard telephone sets may be used. The H680GM supports the full triple play of services including voice and high-speed Internet access services.

The H680GM contains both built-in wire-speed L2 switch and L3 routing gateway with port forwarding, NAT and NAPT address translation, PPPoE client support for high speed Internet service.

Service Scenario for PON

 

h680-service-scenario


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.
