Abstract
A network interface apparatus comprises a bidirectional optical signal port, an optical diplexer connected to the bidirectional optical signal port, a first RF signal port (bidirectional), a second RF signal port, a first RF diplexer, and an RF splitter. The RF diplexer transmits a first received RF input signal from the first RF signal port to the optical diplexer to modulate an optical output signal transmitted by the optical diplexer to the optical signal port. The RF splitter receives from the optical diplexer an RF signal derived from an RF-modulated optical input signal received from the bidirectional optical signal port, transmits a first portion of the derived RF signal as a first RF output signal to the first RF signal port through the first RF diplexer, and transmits a second portion of the derived RF signal as a second RF output signal to the second RF signal port.
