Broadband and baseband LAN

摘要: Described is a communications system for transmitting baseband and broadband signals simultaneously. The ideally suited interconnecting different types of data terminal equipment (DTE) within building or limited geographical area. includes backbone network formed from plurality independent systems. Each the systems dedicated to transmit either signals. A Filter Coupler (FC) combines separates two type at distribution level. One embodiment FC filter coupled in tandem with high frequency transformer. In an alternate balun transformer directional coupler
