A fiber loop carrier-c for broadband service in fiber to the curb

摘要

The present invention relates to a demand-density broadband subscriber optical multiplexing device, which is composed of one channel cell, which is composed of one voice channel up to 512 lines, up to 192 ISDN BRI lines, up to 64 ISDN PRI lines, up to 32 N64kbps high-speed data lines, up to 128 VDSL lines. It is a subscriber optical multiplexing device that optically transmits to the opposite side HDT by multiplexing and demultiplexing with 622 / 155Mbps SDH signal by accepting up to 96 ADSL lines and 4 DS1 (E) dedicated lines. In addition, by providing video service, using ATM technology and bus routing technology, and sharing the unit regardless of service, it can flexibly cope with the operating environment and efficiently use the service band.
