A BROADBAND USER ACCESS DEVICE AND A METHOD FOR BROADBAND USER ACCESS PROCESSING

摘要

A broadband user access device includes an up interface and at least an up channel and a down channel. The down channel at least includes a digital modem, a modulation filter circuit and an electro optical converting module which are connected sequentially, and is used to process the signals received from the up interface and then transmits the signals that have been processed to the user terminal through the fiber connected to the electro optical converting module; the up channel at least includes an photoelectric converting module, a demodulation filter circuit and a digital modem which are connected sequentially, and is used to process the signals received from the user terminal through the fiber connected to the photoelectric converting module and then up transmits the signals that have been processed through the up interface. Another broadband user access device and a method for broadband user access processing both can omit the conversion processing of 2-4 line in the prior art.
