DASAN H660GM Optical Terminal – High-Performance GPON Solution for Operators

The DASAN H660GM is a modern GPON optical terminal designed for telecom operators offering Triple Play services (Internet, TV, telephone). The device provides stable and fast broadband connectivity at a low deployment and maintenance cost.

The H660GM optical terminal from DASAN Networks has been designed for customers seeking economical access to Triple Play services within buildings. Fully compliant with ITU-T G.984 standards, the H660GM model offers transmission speeds of 1.25 Gbps upstream and 2.5 Gbps downstream. Thanks to DASAN’s advanced GPON technology, users can enjoy high-bandwidth multimedia services—such as real-time audio streaming and online gaming—faster and easier than ever before.

The H660GM features one GPON port, four Gigabit Ethernet ports (10/100/1000Base-T), a wireless LAN interface, and two FXS VoIP ports. These interfaces allow the delivery of demanding data, Wi-Fi, and VoIP services. The device uses the Session Initiation Protocol (SIP) for VoIP call handling, enabling seamless integration with existing in-house installations. Standard landline phones can still be used. The terminal supports the full range of Triple Play services, including voice and high-speed Internet access.
