Optical cable modem

摘要

An optoelectronic device can be used by cable modems and cable modem termination systems (CMTS) for digital transmission according to the MCNS/DOCSIS, EuroDOCSIS, DVB/DAVIC or IEEE 802.14 MAC protocols. An optical digital transceiver can be used to transmit the digital signal via an optical fibre network to the subscriber's home (FTTH). A digital electronic circuit implements the physical layer of the MCNS/DOCSIS, EuroDOCSIS, DVB/DAVIC or IEEE 802.14 standards by providing digital processing of the data for the purposes of error correction and distribution of the spectral emissions.
