Abstract
A system is provided implementing an extremely high speed link allowing selection of either twisted pair (or like media) and fiber media in a single local area network to provide a high speed multimedia local area network. A high speed transmission link for twisted pair, coaxial cable media or the like is provided including a transmitter with a conversion device for receiving fiber optic data interface signals intended to drive a fiber optic data interface and for converting said fiber optic data interface signals into high speed transmission link signals of a form suitable to drive a shielded twisted pair medium. A receiver is provided including reconversion apparatus for regenerating the signal received from the shielded twisted pair medium back to an adequate signal level. The transmitter conversion device includes a buffer cooperating with an equalizer and a filter for forming the high speed transmission link signal. The equalizer provides frequency domain compensation for the characteristics of the shielded twisted pair medium. The filter rejects signals outside a band of data signaling. The receiver reconversion apparatus includes a filter connected to said twisted pair mediu…
