GPON (Gigabit Passive Optical Network) is a solution for optical access, offering high speed and great cost benefit for broadband applications and Triple Play services (voice, video and data). This technology allows the sharing of optical fiber among customers, reducing the cost and maximizing the use of band and installed fibers.

ONU DM986 offers a high speed fiber optic access solution. It allows data, voice and video over IP services to be offered to residential users. Ethernet data is transported transparently over the GPON link and delivered to an optical line termination unit (OLT, Optical Line Termination), such as the DM4610 OLT (4-GPON and 8-GPON) and the DM4615 OLT (16- GPON). The DM986 is compatible with the ITU-T G.984 and ITU-T G.988 standards and has a Gigabit Ethernet LAN interface.

This ONU can be provided in two different operating modes, one for operations in Bridge mode and with support for GPON / EPON and the other for operations in Router mode PPPoE or DHCP with support for IPv4 and IPv6 with management by TR-069 and GPON interface. It is also possible to change the UN operation mode between bridge or router via FW update.
