Ht4200-EG4000I industrial ONU is a gigabyte iron shell industrial grade xpon-onu developed and produced by Shenzhen H&T Optoelectronic ., Ltd., which is open and compatible with mainstream OLTS such as Huawei and ZTE. Support the customization of GPON EPON dual-mode. It supports EPON, IPTV, surveillance video, high-speed Internet access, and other application scenarios that require multiple functions, as well as routing functions. It adopts wide temperature design, and can work stably in - 40 ℃ ~ 75 ℃.
HT4200-EG4000I products fully comply with IEEE 802.3ah and China Telecom CTC interconnection standards, with the characteristics of telecom level operation, management and easy maintenance, and are bridge type terminal side equipment.

HT4200-EG4000I realizes commercial service and ultra wideband access through EPON Technology, and ONU PON interface is connected with office equipment through optical fiber. Small structure, supporting desktop, wall or information box in the corridor.

Main features:
● Adopt point to multipoint network topology, effectively collect and gather the scattered Ethernet services of users, provide standard RJ45 Fast Ethernet interface on the user side, and smoothly connect with the existing network.
● Dynamic bandwidth allocation mechanism enables all users to share 1Gbps bandwidth more reasonably, realize reliable quality of service (QoS), and ensure the service quality of different services in the same network.
● Support IGMP multicast and effectively use broadband.
● Support port isolation.
● Support Ethernet loop detection, automatically judge whether there is Ethernet loop blocking in the network connected to the equipment, and automatically recover when the loop disappears.
● Support multicast VLAN.
● Support remote loopback and remote diagnosis of network status.
● Rich OAM function design, including configuration, alarm, performance monitoring, fault isolation and safety management, which not only provides remote management through OLT, but also supports local console management
