4-Port Gigabit POE EPON ONU With 1 Pon port
Model:G2104GP
Introduction
The G2104GP a GEPON FTTB type optical network unit specially developed for the network access at the outdoor environment, which has the Power over Ethernet (PoE) function. The G2104GP is especially designed for AP/IP camera backhaul scenarios, it can provide both data channel and DC power.
Key Features
•Perfect function of PoE： based on the IEEE 802.3af / at standard.
•High QoS：Ensure delay & packet loss requirements using hierarchy QoS.
•Plug and play：Offline provision，support remote configuration, upgrading and diagnosis.
•Carrier grade design：Reliability consideration during hardware, software and system design.
