The AN5121 is a series of GPON FTTB type optical network units specially developed for the network access at the outdoor environment, which has the Power over Ethernet (PoE) and reverse Power over Ethernet (RPoE) function. The AN5121-4GP is especially designed for AP/IP camera backhaul scenarios, it can provide both data channel and DC power. The AN5121-8GR is able to get power source from end user when it’s difficult to get local power feed. The AN5121-4G provides a PON uplink interface and four auto-negotiated GE interfaces. It is an FTTB type GPON optical network unit that can access data services.
High environmental suitability :Use sealed structure with the functions of strong water-proof and dust-proof. Steady operation in extreme conditions.
Perfect function of PoE/RPoE:Supports the PoE/RPoE function, based on the IEEE 802.3af / at standard. Support RPoE function,
HighQoS:Ensure delay & packet loss requirements using hierarchy QoS.
Plug and play:Offline provision, support remote configurationiagnosis.
Carrier grade design:Reliability consideration during hardware, software and system design.
