2 PON OLT GL-E8120T is the crown of the company introduced a new generation of dual-cassette OLT PON port facilities, while both EPON access and switcher function. The product is fully consider the stability, maintainability, ease of use and maneuverability in improving user productivity while ensuring maximum uptime of the network, thus reducing the total cost of ownership for customers. GL-E8120T is a new generation of miniaturized GEPON equipment for telecom operators to provide a carrier-class FTTH broadband access equipment. It has a highly integrated, flexible, high reliability and quality of service provided (QoS) assurance, management, features flexible expansion and networking. GL-E8120T IEEE802.3ah incorporates the latest standards-based EPON system, its optical line, downlink rate of up to 1.25Gb / s. GL-E8120T device provides up 2 GE electrical ports and 2 SFP interfaces (optical optional). 2 1.25G downstream of PON interfaces, splitters provide maximum light 32 branches. The major products for telecom operators to provide last mile fiber access, large customers broadband access solutions, but also applies to broadcasting companies HFC two-way transformation, as well as high-definition video surveillance converged voice transmission and the government, police, large enterprises, video triple-play applications integrated access.
