Description
Energy-efficient NEPTUN GPON 1GE client terminal
The NEPTUN 1GE is a fibre-optic client unit operating in GPON technology used in broadband fibre-optic networks. It uses FTTH / FTTO to deliver data and video services based on GPON technologies. The device supports the G987.3 protocol, making it capable of save energy.

Reliable GPON for home and business
GPON is the latest generation of access network technology operating in the protocol standard. ITU-T G.984. GPON, compared to other standards, is distinguished by higher throughput and greater efficiency through the use of variable length packets. GPON offers efficient user traffic management, frame segmentation, QoS for improved voice and video communication. Networks based on GPON technology provide reliability and performance required for business services.

High-performance GPON ONU for fibre networks
The NEPTUN 1GE is an appliance with a single GE port. The NEPTUN 1GE is high-performance hardware with traffic forwarding capabilities to provide a superior Internet and HD video service experience. The NEPTUN 1GE provides ideal service solutions and future-proof features for fibre network deployments. It works well with equipment from companies such as: Huawei / ZTE/ Fiberhome/ Alcatel-Lucen.
