MAU
Multiple Access Unit for HFC, RFoG, EPON
产品简介
The PBN Multiple Access Unit (MAU) is a networking device designed for multiple apartment buildings, where existing coaxial cabling is used for in-house distribution.
The MAU functions as a receive-only or a bi-directional HFC optical node, together with a Gigabit EPON or an Active Ethernet* uplink and a master unit for Ethernet over Coaxial cable, all together in one small and sturdy enclosure.
The MAU is well suited for HFC networks. It provides high performance CATV delivery together with controlled high-speed broadband data access. Different configurations can be used to allow the MAU to function as a line extender, optical node, optical receiver, and EPON-ONU platform.
The unit integrates many distinct technologies. For the uplinks these are: Conventional Hybrid Fiber Coax (HFC), RF over Glass, Ethernet Passive Optical Networks (EPON), and Active Ethernet*.
The MAU integrates all of these technologies into one advanced and flexible networking solution.
