Abstract
The present disclosure provides a network architecture in which the modem in a hybrid metallic-optical fiber access network is moved from the customer premises to the distribution point. Multiple copper pairs can be used to transmit phantom modes over the copper pairs to the distribution point. Alternatively, or in addition, multiple data signals can be transmitted to a single customer premises with the modem collating the multiple data signals at the distribution point.

A hybrid optical fiber-metallic access network comprising:
- a multiplexer which is connected to an optical fiber cable and connected to a first end of a metallic cable, the multiplexer being located at a first network location;
- and
- a distribution point which is connected to a second end of the metallic cable, the distribution point being located away from a customer premises at a second network location and including a concentrator and a modem, the modem being connected to an apparatus in the customer premises by a further cable,
- wherein, in use,
- the multiplexer is configured to transmit data using a plurality of data channels processed and according to a first protocol, the plurality of data channels being provided by at least two copper pairs in the metallic cable and one or more phantom modes, and
- the modem is configured to receive the plurality of data channels processed according to the first protocol and to transmit the data over the further cable to the customer premises apparatus using a second protocol.
