  • Digital transmission system having modulators remotely located from central media access control layer
    Publication number: 20030066087
    Abstract: A hybrid distributed cable modem termination systems having mini fiber nodes containing CMTS modulators remotely located from the head end. DOCSIS MAC layer components are located at the head end. This lowers cost and allows use of a smaller mFN enclosure. The mFN has A/D converters for DOCSIS upstream traffic and for legacy upstream traffic. A multiplexer using forward error correction combines the legacy and DOCSIS traffic for upstream transmission along a single fiber at rates of approximately 2 Gbps. A splitter at the head end routes legacy traffic to legacy equipment and the DOCSIS traffic to the MAC layer components. A single power supply at the head end can be used to power the mFNs.
