1. An apparatus comprising:

  • an optical connector to optically connect said apparatus to an optic fiber; and

    at least one interface including;

    at least one pair of first and second radio-frequency connectors;

    an optical to radio-frequency converter to convert a downstream optical signal received via said optical connection into an extended downstream radio-frequency signal in an extended downstream frequency band; and

    at least one triplexer to route said extended downstream signal to said first radio-frequency connector;

    to route a legacy downstream radio-frequency signal in a legacy frequency band from said second radio-frequency connector to said first radio-frequency connector; and

    to route a legacy upstream radio-frequency signal in said legacy frequency band from said first radio-frequency connector to said second radio-frequency connector,wherein said extended downstream frequency band comprises at least a sub-set of a frequency band of 1000-3000 MHz.
